  • bleak version: 0.19.9
  • Python version: 3.10
  • Operating System: Android 12

Description

Previously functional kivy app using bleak 0.18.1 compiled to Android doesn't work when compiled in a new build environment with bleak 0.19.0
The program still works as intended in Ubuntu 22 when run using python3

What I Did

try:

device = await BleakScanner.find_device_by_filter(lambda device, advertising_data: device.name == self.connect_to)
					
if device is not None:
					
	async with BleakClient(device,disconnection_callback) as client:
						
		while not self.client.is_connected:
			await asyncio.sleep(0.1)
							
		connection_callback(self.connect_to)

		await client.start_notify(UART_RX_UUID, packet_recieved_callback)

		while client.is_connected:
			await asyncio.sleep(0.1)

except BleakError as e:

report_error(e)

Thanks for the quick response, unfortunately I couldn't get back to this issue until today.

I tried to test your fix but have run into a different issue: I use Buildozer to compile for Android, and every time I build the app it appears to overwrite the modification to the scanner.py file by pulling down a fresh copy of bleak version 0.19.0 via pip.

I haven't found an easy workaround for that, so for now I've just rolled back bleak to 0.18.1. But if you know of any resources for how to work around this I'll gladly give it another try.

Can you tell Buildozer to use https://github.com/hbldh/bleak/archive/refs/heads/android-fix-rssi.zip instead of a version?

That does appear to work. I replaced "bleak" in the requirements with that URL and Buildozer installed bleak 0.20.0a1, and the bluetooth now works in my app.
