logs are needed. Ideally verbose logs.

please reopen when you have logs.

I'm not aware of any code in FBP that would cause this.

you need to stop listening to the stream (i.e. call cancel) when you disconnect

// Setup Listener for characteristic reads
final subscription = characteristic.onValueReceived.listen((value) {
    // do something with new value
});

// listen for disconnection
device.connectionState.listen((BluetoothConnectionState state) async {
    if (state == BluetoothConnectionState.disconnected) {
        // stop listening to characteristic
        subscription.cancel();
    }
});

// enable notifications
await characteristic.setNotifyValue(true);
