Connecting to the Glider Canopy Flasher Wi-Fi

The Glider Canopy Flasher creates its own local Wi-Fi access point when the controller is switched on.

This network is used to open the configuration pages, test flash patterns and install firmware updates. It does not provide internet access.

Wi-Fi Network Name

The Wi-Fi network name uses the following format:

RTOIP-<serial number>

For example, a controller with the serial number:

FLR-A5C35B-EB

creates the Wi-Fi network:

RTOIP-FLR-A5C35B-EB

The serial number can therefore be read directly from the Wi-Fi network name displayed by the phone or computer.

Wi-Fi Password

The Wi-Fi password is the controller serial number without the RTOIP- prefix.

Using the example above:

  • Wi-Fi network: RTOIP-FLR-A5C35B-EB
  • Password: FLR-A5C35B-EB

Enter all letters, numbers and hyphens exactly as displayed.

The password is intentionally easy to obtain from the network name so that the pilot or installer does not need to find a separate password label while working in the cockpit.

The Glider Canopy Flasher network is a local configuration connection with limited range and normally remains available for only a short period after startup. It does not provide access to the internet or to the aircraft FLARM itself.

This makes the practical risk of unwanted access low during normal use, although it is not zero. Do not leave the configuration access point permanently enabled unless continuous Wi-Fi access is required.

Opening the Configuration Page

After connecting to the Glider Canopy Flasher Wi-Fi network, open a web browser and enter:

http://172.27.149.1

Enter the complete address, including http://.

The main Glider Canopy Flasher configuration page should then appear.

Connecting with an Android Phone or Tablet

  1. Switch on the Glider Canopy Flasher.
  2. Open Settings on the Android device.
  3. Open Network & internet, Connections or Wi-Fi. The exact name depends on the phone manufacturer.
  4. Turn Wi-Fi on.
  5. Wait for the list of available networks to appear.
  6. Select the network beginning with RTOIP-.
  7. Use the part after RTOIP- as the password.
  8. Press Connect.
  9. If Android reports that the network has no internet access, select an option such as Stay connected, Connect anyway or Use this network as is.
  10. Open Chrome or another browser.
  11. Enter http://172.27.149.1 in the address bar.

Android No-Internet Message

Android may display messages such as:

  • No internet access;
  • Connected without internet;
  • This network has no internet;
  • Internet may not be available.

This is normal. The Glider Canopy Flasher Wi-Fi network is used only for direct communication with the controller.

Choose the option that keeps the phone connected to the network.

If the phone repeatedly changes back to mobile data or another Wi-Fi network:

  • temporarily disable mobile data;
  • temporarily disable automatic network switching or adaptive connectivity;
  • forget another nearby Wi-Fi network if the phone keeps reconnecting to it;
  • reconnect to the RTOIP network and select the option to remain connected.

Connecting with an iPhone or iPad

  1. Switch on the Glider Canopy Flasher.
  2. Open the iPhone or iPad Settings app.
  3. Select Wi-Fi.
  4. Make sure Wi-Fi is switched on.
  5. Wait for the available networks to appear.
  6. Select the network beginning with RTOIP-.
  7. Use the part after RTOIP- as the password.
  8. Tap Join.
  9. Remain connected if the iPhone reports that the network has no internet connection.
  10. Open Safari.
  11. Enter http://172.27.149.1 in the address bar.

iPhone No-Internet Message

The iPhone may show No Internet Connection beneath the RTOIP network name. This is expected and does not indicate a fault.

The phone is communicating directly with the Glider Canopy Flasher rather than connecting through it to the internet.

If Safari does not open the configuration page:

  • confirm that the RTOIP network remains selected;
  • temporarily turn off mobile data;
  • temporarily disable any VPN service;
  • close and reopen Safari;
  • enter the full address http://172.27.149.1.

Connecting with a Windows 11 Computer

  1. Switch on the Glider Canopy Flasher.
  2. Click the network, sound and battery area on the right side of the Windows taskbar.
  3. Click the arrow beside the Wi-Fi button to display available networks.
  4. Select the network beginning with RTOIP-.
  5. Click Connect.
  6. Enter the part after RTOIP- as the network password.
  7. Click Next.
  8. Open Microsoft Edge, Chrome, Firefox or another web browser.
  9. Enter http://172.27.149.1 in the address bar.

Windows No-Internet Message

Windows may display the RTOIP connection as:

No internet, secured

This is normal. The Wi-Fi connection is secured and is working locally, but it does not provide internet access.

Do not disconnect from the RTOIP network merely because Windows displays the no-internet message.

Configuration Access-Point Time

The configuration Wi-Fi access point normally remains available for approximately 120 seconds after the controller starts.

The timer runs only while no Wi-Fi device is connected. Once a phone, tablet or computer connects, the access point remains active while that device stays connected.

After the final device disconnects, the configured timer starts again.

If the RTOIP network is not visible:

  1. switch the Glider Canopy Flasher off;
  2. wait several seconds;
  3. switch it on again;
  4. refresh the available Wi-Fi network list.

The access-point active time can be changed in the Glider Canopy Flasher configuration. Setting it to 0 keeps the access point permanently active.

If the Configuration Page Does Not Open

Check the following:

  • the phone or computer is connected to the correct RTOIP network;
  • the Wi-Fi password matches the serial number exactly;
  • the browser address is http://172.27.149.1;
  • the browser has not automatically changed the address to HTTPS;
  • mobile data or another Wi-Fi network has not taken priority;
  • a VPN or security application is not redirecting local traffic;
  • the controller is still powered;
  • the Wi-Fi configuration period has not expired.

If necessary, restart the Glider Canopy Flasher, reconnect to its Wi-Fi network and try again.

Browser Security and HTTP Connection

The Glider Canopy Flasher configuration page uses a direct local HTTP connection. It does not use an internet security certificate and does not provide an HTTPS connection.

Because of this, the browser may display messages such as:

  • Not secure;
  • Connection is not secure;
  • Secure connection not available;
  • This site does not support HTTPS.

This is expected when accessing the Glider Canopy Flasher directly at its local address. For this specific connection, the warning can be ignored and the browser can be instructed to continue to the HTTP page.

Do not ignore similar warnings on normal internet websites, particularly when entering passwords, payment details or personal information.

Correct Address

After connecting to the Glider Canopy Flasher Wi-Fi network, enter the following address in the browser address bar:

172.27.149.1

Most browsers will recognise this as a local network address and open the configuration page automatically.

If the browser performs an internet search, reports that the secure page is unavailable or automatically changes the address to HTTPS, enter the complete address:

http://172.27.149.1

Do not use:

https://172.27.149.1

The Glider Canopy Flasher configuration server uses HTTP, not HTTPS.

  • the phone or computer remains connected to the RTOIP Wi-Fi network;
  • the browser is using http:// rather than https://;
  • mobile data or another Wi-Fi network has not taken priority;
  • a VPN is not redirecting local network traffic;
  • the Glider Canopy Flasher remains powered;
  • the configuration Wi-Fi access point has not timed out.

If necessary, restart the Glider Canopy Flasher, reconnect to its RTOIP Wi-Fi network and open http://172.27.149.1 again.

Normal and Alarm Pattern Configuration

This section of the configuration page allows a separate flash pattern to be selected for each operating level:

  • Normal — used during normal operation when no FLARM alarm is active;
  • Alarm Level 1 — activated automatically when FLARM reports a Level 1 alarm;
  • Alarm Level 2 — activated automatically when FLARM reports a Level 2 alarm;
  • Alarm Level 3 — activated automatically when FLARM reports a Level 3 alarm.

Each level can use a different pattern and a different rest time. This allows a low-consumption pattern to be used during normal flight and progressively more noticeable patterns to be used for higher FLARM alarm levels.

Sequence

The Sequence list selects the flash pattern used for that operating level.

The available choices include:

  • 22 predefined patterns, P1–P22; and
  • 4 user-programmable patterns.

The predefined patterns contain different combinations of single, double, triple and multi-flash sequences. User-programmable patterns allow the pulse duration, spacing and number of flashes to be configured separately.

Rest Time

The Rest ms setting defines the pause after the complete flash sequence before the sequence starts again.

The rest time can be adjusted independently for all predefined and user-programmable patterns.

For example, if a selected pattern produces three flashes, the complete operating cycle is:

  1. the first flash;
  2. the internal pause;
  3. the second flash;
  4. the internal pause;
  5. the third flash;
  6. the configured rest time;
  7. the sequence starts again.

Increasing the rest time:

  • reduces the number of flashes per minute;
  • reduces the average duty cycle;
  • reduces estimated battery consumption;
  • reduces average thermal loading.

Reducing the rest time has the opposite effect and causes the sequence to repeat more frequently.

Calculated Pattern Information

The information panel below each level is recalculated automatically whenever the selected sequence or rest time is changed.

It displays:

  • the calculated duty cycle;
  • the average number of flashes per minute;
  • the IGC competition flash-rate indication;
  • the estimated average flashing current;
  • a high-duty warning where applicable.

Duty Cycle

The Duty value shows the percentage of the complete repeating cycle during which the LEDs are switched on.

The calculation includes:

  • all individual light pulses in the sequence;
  • the pauses between the pulses;
  • the configured rest time after the sequence.

A lower duty cycle normally means lower average battery consumption and lower average heat generation.

Patterns with a duty cycle above approximately 20% are identified as high-duty patterns.

High-Duty Warning

When the calculated duty cycle exceeds approximately 20%, the configuration page displays:

WARNING: HIGH DUTY >20%

This is separate from the IGC flash-rate indication. A pattern can be within the IGC flash-rate range but still have a high duty cycle, or it can be outside the IGC flash-rate range while maintaining a low duty cycle.

High-duty patterns increase average battery consumption and thermal loading. Before testing or saving such a pattern, the controller may ask the user to confirm that the warning has been understood.

The acknowledgement is stored in non-volatile memory so that the controller can remember that the selected high-power configuration has been accepted.

Flashes per Minute

The flashes/min value shows the calculated average number of individual light flashes produced in one minute.

For multi-flash patterns, every individual light pulse is counted as one flash.

For example, one complete triple-flash sequence produces three flashes. The average rate is calculated using the duration of the complete repeating cycle, including the configured rest time.

The displayed value is recalculated immediately when the rest time is changed.

IGC Competition Flash-Rate Indication

The current FAI/IGC Sporting Code Annex A requires competing sailplanes at FAI World and Continental Gliding Championships to have an installed red or white strobe light that is clearly visible to oncoming traffic.

The specified flash rate is:

40 to 100 flashes per minute

This requirement applies to FAI World and Continental Gliding Championships governed by Sporting Code Section 3, Annex A, including the relevant Junior and Women’s championships.

The organisers may also publish additional requirements in the competition Local Procedures. Other competitions may choose to adopt the same requirement, so pilots should always check the rules for the particular event.

The Glider Flasher configuration page automatically compares the calculated average flash rate with the 40–100 flashes-per-minute range.

It displays:

  • IGC avg. rate OK — the calculated average rate is between 40 and 100 flashes per minute;
  • IGC avg. rate NOT OK — the calculated average rate is below 40 or above 100 flashes per minute.

What “IGC Avg. Rate Not OK” Means

An “IGC avg. rate NOT OK” message does not mean that the pattern is faulty, unsafe or unsuitable for normal flying.

It only means that the calculated average flash rate is outside the specific 40–100 flashes-per-minute range used for the relevant level of FAI/IGC competition.

Patterns outside this competition range are fully valid for normal flying and may be deliberately selected as more noticeable FLARM alarm patterns.

For example, a rapid Level 2 or Level 3 alarm pattern may produce considerably more than 100 flashes per minute. This can provide a strong attention-getting indication during a traffic alert, even though it is outside the average rate specified for the applicable FAI World and Continental Championship rule.

The IGC information is provided specifically to help pilots who take part in competitions where this rule applies. It allows them to adjust the rest time and immediately see whether the selected configuration is within the required average flash-rate range.

Scope of the IGC Check

The displayed IGC indication checks the calculated average flash rate only.

It does not independently confirm:

  • the brightness of the completed installation;
  • visibility from every viewing angle;
  • installation approval;
  • compliance with additional Local Procedures;
  • acceptance of the installation by competition organisers.

The pilot remains responsible for checking the current rules and Local Procedures for the particular competition.

Estimated Flashing Current

The estimated flashing current value shows the approximate average aircraft-supply current attributable to the selected flashing pattern.

The estimate is based on representative operation from a 13.5 V aircraft electrical supply and the calculated pattern duty cycle.

It is intended to help compare patterns and estimate their relative effect on battery consumption.

The displayed flashing-current estimate does not include all current used by the controller and enabled wireless functions. The complete aircraft current may also include:

  • the controller electronics;
  • the Wi-Fi access point;
  • Wi-Fi UDP FLARM output;
  • Bluetooth Classic;
  • Bluetooth Low Energy.

Test Button

The Test button temporarily activates the pattern configured for that level.

The test runs for approximately ten seconds and then automatically returns to the pattern required by the current operating state.

This allows the selected sequence and rest time to be checked without permanently forcing the system into that operating level.

When testing a high-duty pattern, an additional warning and confirmation may be displayed.

Recommended Configuration Procedure

  1. Select the required sequence for Normal operation.
  2. Set the Normal rest time.
  3. Check the duty cycle, flashes per minute and estimated current.
  4. If competition use is intended, check the IGC average-rate indication.
  5. Use the Test button to examine the selected pattern.
  6. Repeat the procedure for Alarm Levels 1, 2 and 3.
  7. Use progressively stronger patterns for higher alarm levels where appropriate.
  8. Review any high-duty warning before saving the configuration.
  9. Save the completed settings.

Example Shown

In the example configuration:

  • the Normal pattern produces approximately 41 flashes per minute and is inside the IGC competition range;
  • the Alarm Level 1, 2 and 3 patterns produce more than 100 flashes per minute and are therefore shown as outside the IGC average-rate range;
  • the faster alarm patterns remain suitable for normal non-competition operation;
  • the Alarm Level 3 configuration also exceeds 20% duty cycle and therefore displays a separate high-duty warning.

The red IGC message beside the alarm patterns relates only to the competition flash-rate range. The orange high-duty warning is a separate indication relating to average power consumption and thermal loading.

User-Defined Sequences

This section allows four independent custom flash sequences to be created.

The four user-defined sequences are available in addition to the 22 predefined patterns. Any saved user-defined sequence can be selected for Normal operation or any FLARM alarm level. The sequence number does not restrict where the pattern can be used.

Sequence Settings

Each user-defined sequence is configured using four values:

  • Pulses — the number of individual flashes in one sequence;
  • ON ms — the duration of each flash in milliseconds;
  • Spacing ms — the interval between consecutive flashes within the sequence;
  • Rest ms — the pause after the final flash before the complete sequence repeats.

Pulses

The Pulses setting determines how many individual flashes are produced in each sequence.

For example:

  • 1 pulse creates a single-flash sequence;
  • 2 pulses create a double-flash sequence;
  • 3 pulses create a triple-flash sequence;
  • 6 pulses create a six-flash sequence.

ON Time

The ON ms setting determines how long the LEDs remain illuminated during each individual flash.

The value is entered in milliseconds. For example, an ON time of 60 ms means that every pulse remains active for 0.06 seconds.

Increasing the ON time creates a longer flash and also increases the average power and thermal loading of the sequence.

Pulse Spacing

The Spacing ms setting determines the interval between individual flashes within the same sequence.

A shorter spacing value creates a rapid, closely grouped burst. A longer spacing value makes the individual flashes more clearly separated.

For a three-pulse sequence, operation is:

  1. first flash;
  2. configured spacing;
  3. second flash;
  4. configured spacing;
  5. third flash;
  6. configured rest period;
  7. the sequence repeats.

Rest Time

The Rest ms setting determines the pause after the final pulse before the sequence starts again.

Increasing the rest time makes the sequence repeat less frequently. Reducing it makes the complete sequence repeat more frequently.

Testing Unsaved Values

The Test user button operates the selected user sequence using the values currently displayed on the page.

The values do not need to be saved before testing. This allows the sequence to be adjusted and tested repeatedly until the required result is achieved.

The test runs for approximately ten seconds and then the flasher returns to the pattern required by its current operating state.

Testing a sequence does not permanently save the displayed values.

Temporary RAM Storage

Values used during testing are held temporarily in RAM.

Temporary values will be lost if:

  • the controller is restarted;
  • aircraft power is removed;
  • the page is reloaded before the configuration is saved.

Saving to Non-Volatile Memory

After the four sequences have been configured, press Save configuration to write them to non-volatile memory.

Once saved, the user-defined sequences remain stored after power is removed and are restored automatically the next time the Glider Flasher starts.

Assigning a User-Defined Sequence

Saving a user-defined sequence does not automatically assign it to an operating level.

After saving, return to the main pattern configuration section and select the required user sequence for:

  • Normal operation;
  • FLARM Alarm Level 1;
  • FLARM Alarm Level 2;
  • FLARM Alarm Level 3.

The same user-defined sequence may be assigned to more than one operating level, and any of the four user-defined sequences may be used for any level.

Recommended Configuration Procedure

  1. Select the required number of pulses.
  2. Set the duration of each pulse.
  3. Set the spacing between pulses.
  4. Set the rest period after the sequence.
  5. Review the automatically calculated pattern information.
  6. Press the Test button to check the sequence.
  7. Adjust and test the values as required.
  8. Press Save configuration to store the final settings permanently.
  9. Assign the saved sequence to the required Normal or FLARM alarm level.

FLARM Serial and Behaviour

This section configures the wired FLARM connection, optional wireless FLARM data outputs, configuration Wi-Fi timing and speed-controlled Normal flashing.

FLARM Baud

The FLARM baud setting must match the baud rate of the serial output from the connected FLARM device.

Supported baud rates are:

  • 19,200 baud;
  • 38,400 baud;
  • 57,600 baud;
  • 115,200 baud.

The standard setting is 19,200 baud. If the selected value does not match the FLARM output, the controller will not be able to interpret the received data correctly.

After changing the baud rate, save the configuration and restart the controller so that the serial interface starts using the new setting.

Clone FLARM Stream

The Clone FLARM stream setting controls whether the FLARM data received through the wired serial input is retransmitted through Bluetooth.

The available options are:

  • None — no Bluetooth FLARM output;
  • BT — FLARM data is transmitted through Bluetooth Classic;
  • BLE — FLARM data is transmitted through Bluetooth Low Energy;
  • BT and BLE — both Bluetooth outputs operate at the same time.

The selected output carries a copy of the incoming FLARM data stream for use by compatible navigation applications and cockpit devices.

Bluetooth Classic and Bluetooth Low Energy can therefore be used without requiring an additional physical connection to the FLARM serial output.

Selecting a Bluetooth option keeps the required Bluetooth service active after the configuration Wi-Fi access point has shut down. It does not keep the configuration Wi-Fi access point active.

Share FLARM Stream over Wi-Fi UDP

Enable Share FLARM stream over Wi-Fi UDP to transmit the received FLARM data over Wi-Fi using UDP.

This output can be used by compatible navigation applications running on phones, tablets and other Wi-Fi-equipped cockpit devices.

The Wi-Fi UDP output operates independently of the Bluetooth selection. It can therefore be used:

  • on its own;
  • together with Bluetooth Classic;
  • together with Bluetooth Low Energy;
  • together with both Bluetooth services.

When UDP sharing is enabled, the Wi-Fi service remains active so that the FLARM data stream can continue to be transmitted.

UDP Port

The UDP port setting specifies the network port used to transmit the FLARM data.

The default port is:

4353

The receiving navigation application must be configured to listen on the same UDP port.

The default value should normally be retained unless another device or application requires a different port.

Configuration Wi-Fi AP Active Time

The Configuration Wi-Fi AP active time setting controls how long the configuration Wi-Fi access point remains available after the controller starts.

The value is entered in seconds.

  • 0 — the configuration access point remains available continuously;
  • 60 or more — the access point shuts down after the selected period of inactivity;
  • 120 — the standard setting, providing two minutes of access.

Values between 1 and 59 seconds are not used because the minimum timed operating period is 60 seconds.

Wi-Fi Timer Behaviour

The access-point timer runs only when no Wi-Fi device is connected.

While a phone, tablet or computer remains connected, the access point stays active and the timer does not expire.

After the last connected device disconnects, the full configured timer starts again.

This prevents the Wi-Fi access point from switching off while the user is actively configuring the flasher.

If the configuration access point has shut down, restart the controller to make it available again.

Bluetooth Classic or BLE cloning keeps the selected Bluetooth service active but does not prevent the configuration Wi-Fi access point from shutting down.

Speed-Controlled Normal Flashing

Enable Normal flashing only above speed when FLARM comms are valid to suppress the Normal pattern while the aircraft is below the configured speed.

This can reduce unnecessary flashing and battery consumption while the aircraft is stationary, being prepared for flight or moving slowly on the ground.

The function is used only when valid FLARM navigation data containing aircraft speed is being received.

Minimum Speed for Normal Flashing

The Minimum speed for normal flashing setting defines the speed above which the Normal pattern is allowed to operate.

The value is entered in kilometres per hour.

For example, with the threshold set to 40 km/h:

  • below 40 km/h, the Normal pattern is suppressed while valid FLARM speed data is available;
  • at or above 40 km/h, the selected Normal pattern operates normally.

Effect on FLARM Alarm Patterns

Speed control affects the Normal pattern only.

When FLARM reports Alarm Level 1, 2 or 3, the pattern assigned to that alarm level starts regardless of the aircraft speed.

A traffic alarm therefore always takes priority over the Normal flashing speed threshold.

Loss of FLARM Communication

The speed-control function is fail-safe.

If no valid FLARM message is received for approximately five seconds:

  • speed control is ignored;
  • the controller assumes that reliable speed information is unavailable;
  • the selected Normal pattern is forced on.

Loss of FLARM communication therefore does not leave the visual-awareness light switched off.

Saving the Configuration

Press Save configuration to write the settings from this page to non-volatile memory.

The saved settings are restored automatically whenever the controller is powered or restarted.

Hardware Reset

The Hardware reset button restarts the controller.

It does not erase the saved configuration or restore factory settings. It can be used after changing a setting that takes effect only during startup, such as the FLARM serial baud rate.

Firmware Update

The Firmware update button opens the browser-based software update page.

This allows an approved firmware file to be installed through Wi-Fi without opening the controller or connecting a USB programming cable.

Stop Flashing

The Stop flashing button immediately disables the LED output.

This can be used during ground configuration, inspection or testing when light output is not required. It does not erase the selected patterns or other saved settings.

Restart the controller to return to normal automatic operation.

Current-Consumption Information

The information panel below this section explains the basis used for the displayed duty-cycle and flashing-current estimates.

The estimates are based on the standard six-LED, 1 A version operating from a representative 13.5 V aircraft supply. Higher-current hardware versions consume proportionally more current.

Allow approximately:

  • 7 mA for the controller electronics with Wi-Fi off;
  • approximately 30 mA while the configuration Wi-Fi access point is active.

These controller values are additional to the estimated current produced by the selected flashing pattern.

Firmware Update

The Glider Canopy Flasher firmware can be updated wirelessly through the built-in web interface. The controller does not need to be removed from the aircraft, opened or connected to a USB programming cable.

Only install a firmware update file supplied specifically for the Glider Canopy Flasher.

Before Starting

Before beginning an update:

  • ensure that the aircraft battery or external power supply is sufficiently charged and stable;
  • remain connected to the Glider Canopy Flasher Wi-Fi network;
  • do not switch off the controller during the update;
  • do not close or reload the browser page while the file is being uploaded;
  • use only the supplied Glider Canopy Flasher firmware file.

Firmware Slots

The Firmware slots table displays technical information about the controller’s internal firmware storage.

The controller contains two separate firmware slots:

  • one slot containing the firmware currently in use;
  • another slot available for the next update.

The roles displayed in the table are:

  • Active — the firmware slot currently running;
  • Boot — the slot selected for startup;
  • Next update — the slot into which the new firmware will be written.

The remaining values, including the slot label, subtype, address and size, are internal technical information. They do not normally provide any useful information for the user and do not need to be changed or interpreted.

State Shown as Undefined

The manual screenshot was taken from a development Glider Canopy Flasher controller on which automatic software-state confirmation was disabled.

For this reason, the State field in the screenshot is shown as undefined. This was expected on that development device and does not indicate a firmware fault or a problem with the update page.

The displayed state may be different in the production firmware.

Selecting the Update File

  1. Press Browse or Choose file.
  2. Select the supplied firmware file from the phone, tablet or computer.
  3. Confirm that the correct filename is displayed beside the file-selection button.
  4. Press Upload and restart.

The firmware file normally uses the .bin filename extension.

Do not rename, modify or extract the firmware file unless specifically instructed to do so.

Update Progress

After Upload and restart is pressed, a progress bar appears below the button.

The progress bar shows how much of the firmware file has been transferred to the controller. The name of the file being uploaded is also displayed.

During this stage:

  • keep the browser page open;
  • keep the device connected to the Glider Canopy Flasher Wi-Fi network;
  • do not switch off aircraft power;
  • do not press the browser Back or Refresh buttons;
  • do not start another update.

Automatic Restart

When the upload has completed successfully, the controller stores the firmware in the alternate firmware slot and restarts automatically.

The Wi-Fi connection and browser page may temporarily disconnect during the restart. This is normal.

Allow the controller time to restart, then reconnect to the Glider Canopy Flasher Wi-Fi network if required and open the configuration page again.

After the Update

After reconnecting:

  1. check the firmware version displayed on the configuration page;
  2. confirm that the saved configuration is still correct;
  3. test the Normal pattern;
  4. check FLARM communication where connected;
  5. check any enabled Bluetooth, BLE or Wi-Fi UDP outputs.

Normal configuration settings are stored separately from the firmware and should remain available after a routine update.

If the Update Does Not Start

If pressing Upload and restart does not begin the update, check that:

  • a firmware file has been selected;
  • the selected file is the correct Glider Canopy Flasher firmware file;
  • the browser is still connected to the Glider Canopy Flasher Wi-Fi network;
  • the controller remains powered;
  • the file has not been renamed, altered or corrupted.

Do not repeatedly remove power while an update is being written. Restart the controller and attempt the update again only after confirming that the previous upload is no longer in progress.

Standard Pattern List and Test

Pressing the Pattern list button on the main configuration page opens the complete list of the 22 predefined Glider Canopy Flasher patterns.

This page allows the user to:

  • review the timing and operating characteristics of every predefined pattern;
  • compare duty cycle, flash rate and estimated consumption;
  • identify lower-consumption and high-duty patterns;
  • test any predefined pattern directly.

The predefined pattern parameters cannot be edited on this page. When a pattern is assigned to Normal operation or a FLARM alarm level, its Rest ms value can be adjusted separately on the main configuration page.

Current Pattern

The line beginning with Current shows the pattern that is currently operating.

The corresponding row in the table is also highlighted, making it easy to identify the active pattern.

Wi-Fi Information

The information near the top of the page identifies:

  • the Glider Canopy Flasher Wi-Fi access-point name;
  • the unit identifier or serial number;
  • the local IP address used to access the web interface.

Pattern Table

Each row represents one of the 22 predefined patterns, P1–P22.

No

The No column shows the numerical position of the pattern in the list.

Name

The Name column shows the pattern number and a short descriptive name.

Examples include:

  • soft triple;
  • crisp quad;
  • fast strobe;
  • block triple;
  • ECO triple.

The name gives a general indication of the visual character of the pattern.

Pulses

The Pulses column shows how many individual flashes are produced during one complete burst.

For example, a triple pattern contains three flashes, while a ten-pulse pattern contains ten flashes.

ON ms

The ON ms column shows how long each individual flash remains illuminated.

The value is shown in milliseconds.

Spacing ms

The Spacing ms column shows the interval from the beginning of one flash to the beginning of the next flash within the same burst.

This value includes both the LED ON time and the following dark interval.

OFF Gap ms

The OFF gap ms column shows the actual dark period between the end of one flash and the beginning of the next flash.

It is calculated from the pulse spacing minus the LED ON time.

Burst ms

The Burst ms column shows the total duration of the grouped flash burst, measured from the beginning of the first pulse to the end of the final pulse.

It does not include the longer rest period after the burst.

Rest ms

The Rest ms column shows the default pause after the final flash before the complete pattern repeats.

When the pattern is selected on the main configuration page, this rest time can be adjusted independently for Normal operation and each FLARM alarm level.

Cycle ms

The Cycle ms column shows the duration of one complete repeating cycle.

It includes:

  • the complete flash burst;
  • the rest period following the burst.

Duty

The Duty column shows the percentage of the complete cycle during which the LEDs are illuminated.

Patterns above approximately 20% duty are marked HIGH DUTY.

High-duty patterns produce greater average battery consumption and greater thermal loading. They are primarily intended for short-duration or special-purpose use.

Flashes per Minute

The Flashes/min column shows the average number of individual light flashes produced during one minute.

Each individual pulse within a multi-pulse burst is counted as one flash.

IGC Average Rate

The IGC avg. rate column compares the calculated flash rate with the 40–100 flashes-per-minute range applicable to the relevant FAI/IGC competition requirement.

  • OK means the average flash rate is within that range.
  • NOT OK means the average flash rate is below 40 or above 100 flashes per minute.

An IGC NOT OK indication does not mean that the pattern is faulty or unsuitable for normal flying. It only means that its average flash rate is outside that specific competition range.

Estimated Flashing Current

The Est. flashing mA column shows the estimated average aircraft-supply current used by the flashing pattern.

The displayed estimate is based on the standard six-LED, 1 A Glider Canopy Flasher version operating from a representative 13.5 V aircraft supply.

The estimate is intended mainly for comparing the relative battery consumption of different patterns.

Description

The Description column provides a plain-language summary of the pattern timing.

It shows:

  • the number of pulses;
  • the ON duration of each pulse;
  • the dark gap between pulses;
  • the default rest period after the burst.

Flash Button

The Flash button in the Action column temporarily tests the corresponding predefined pattern.

The test uses the timing values shown in that row and operates for approximately ten seconds. The controller then returns to the pattern required by its current operating state.

Testing a pattern from this page does not change the saved Normal or FLARM alarm assignments.

Configuration Button

The Configuration button returns to the main Glider Canopy Flasher configuration page.

Use the main configuration page to:

  • assign patterns to Normal operation and FLARM alarm levels;
  • adjust the rest time;
  • configure user-defined sequences;
  • save settings to non-volatile memory.

Firmware Update Button

The Firmware update button opens the wireless firmware-update page.

Stop Button

The Stop button immediately stops the LED output. It is intended for ground testing, inspection or situations where the light output needs to be stopped quickly.

ECO Patterns

Patterns P19–P22 are lower-consumption ECO patterns.

They use a longer default rest period of approximately three seconds and remain below approximately 10% duty cycle.

These patterns are intended for normal operation where lower average battery consumption is preferred.

Selecting a Pattern

The Pattern List page is used for reviewing and testing the predefined patterns. It does not assign the selected pattern permanently.

To use a pattern:

  1. review or test the required pattern on this page;
  2. press Configuration;
  3. select the pattern for Normal operation or the required FLARM alarm level;
  4. adjust the rest time where required;
  5. press Save configuration.

After Configuration

Press Save configuration before leaving the configuration page if any settings have been changed.

When configuration is complete, the phone or computer can be disconnected from the RTOIP network and reconnected to its usual Wi-Fi network.
