Troubleshooting

Fix common WingView setup, display, network, and map problems. Nothing here harms your board or removes saved settings.

Updates fail, but the board otherwise works

Restart the board first. This returns it to the previous firmware version without removing settings.

Follow the Recovery Guide for the full steps and support-log instructions.

Nothing appears on screen

Touch the screen first. After 15 minutes, the display sleeps. A touch or knob turn restores it.

Set the timeout in Settings → Sleep after. Choose 15, 30, or 60 minutes.

You can show a clock while the display sleeps. Set this in Settings → When asleep. Touch the screen to return to the scope.

If touching the screen does nothing, check power. Try another port, charger, or cable. If the board has never been flashed, it stays dark until you install firmware.

The flashing tool cannot find the board

Use a cable that carries data. Charge-only cables are common.

Check that your computer detects the port. On Linux, look for /dev/ttyACM0. On Windows, look for a COM port.

Demo traffic does not disappear

Your WingView does not have a working feed. Hold the N button and check the status screen:

• no auth means your API key was rejected.

• no internet means the board cannot reach the internet.

• api down means our API did not answer.

Demo traffic is expected whenever the board has no working feed.

Aircraft appear, but no map

The selected location probably has no maps. Open locations to check each location.

A failed or interrupted map build leaves no partial maps. Start the build again.

The board only uses a map set after every range is written. This prevents incomplete maps.

The map disappears when you zoom in

The board is using maps built for a nearby location. It stops using them at closer ranges to avoid map misalignment.

The location tolerance is 3% of the displayed range. It is about 5.5 km at 100 NM and 170 m at 3 NM.

This usually happens when you have nearby locations. It can also happen near Los Angeles, where demo maps are centered. Build maps for the location you are using.

You cannot reach the web page

Open the settings menu. Select Wi-Fi setup to restore the board's setup network.

The page requests a passphrase you do not have

Press and hold the N button to open the status screen. Find the page pass row.

The passphrase uses lowercase letters only. Replace it in Settings → New passphrase if needed.

An erase appears to do nothing

Each erase option requires confirmation on the board. Touch and hold the screen for about 2.5 seconds. A ring sweeps around the display. The erase starts when it closes.

A quick tap cancels the erase. On the Elecrow, you can press the knob instead.

The web page cannot erase the board by itself. If the display is asleep, it wakes for the confirmation.

You cannot reach the web page or settings menu

Install the firmware again from the browser. Follow the same steps as your original setup:

1. Plug the board into a computer.

2. Open the WingView install page in Chrome or Edge.

3. Select Install.

4. Select no when asked whether to erase first.

Your Wi-Fi, API key, locations, and maps remain saved.

This works even when nothing else on the board works. It does not use the network, web page, or running firmware.
