NoneType error when calling client.pair() on Android #1531

Open skywodd opened 1 month ago

skywodd commented 1 month ago

Description

The p4android backend seem to have a bug in the BleakClientP4Android.pair() method. When called, the function is working but always crash with the exception TypeError: object NoneType can't be used in 'await' expression.

This is caused by the line await receiver.stop(). It look like the BroadcastReceiver.stop() method is just a plain def, not a async def : https://github.com/kivy/python-for-android/blob/develop/pythonforandroid/recipes/android/src/android/broadcast.py#L67

What I Did

Run the kivy example with an added await client.pair() after the client connection.
