Solving issues with Weatherflow WeatherMeter connection

1. You don’t need to create a Bluetooth pair with Weatherflow WEATHERmeter. If you created, delete it.

2. Some devices on Android needs location service to be turned on to use Bluetooth (I don't know why). Turn GPS on.

3. Weatherflow app can stay in background and keep Bluetooth port. Check settings of Weatherflow app (if installed) and turn background mode off

4. Delete Weatherflow app if it not used

5. Turn Bluetooth on and off

6. Clear Bluetooth cache (Android)

7. Restart the phone

8. Unistall and install again Strelok Pro if all items above does not help

Note for Android 12 phone owners. Make sure what Strelok Pro has granted permission to access nearby devices via Bluetooth.

Notes

After some modification you can use Kestrel vane for the WEATHERmeter (see photo).
