If the app isn’t connecting to your ZLEDS controller, try the following troubleshooting steps:
-
Ensure your lights are powered on.
The Bluetooth module only activates when the tail lights receive power (usually when running lights are on). -
Enable Bluetooth permissions.
Make sure the ZLED Bit Editor app has all required permissions (Bluetooth, location, etc.) — especially on Android 11+. -
Select the correct device.
When the Bluetooth scan list appears, select the device labeledZLEDS-XXXX. -
Restart the app and power cycle the lights.
If tabs do not appear or the screen remains black:-
Close the app completely.
-
Turn the lights off for 5–10 seconds.
-
Turn the lights back on.
-
Reopen the app.
-
-
Verify Access ID.
If the wrong Access ID is entered, the app will block access with a black screen and exclamation icon.
If issues persist, try reinstalling the app or contacting ZLEDS support for further assistance.
