BLE device disconnect, then two opposite exception BleAlreadyConnectedException vs BleDisconnectedException
I'm working on a DFU OTA (device firmware update on the air).
To do it, I must connect the device, then send a command to order the device to switch to bootloader mode. After this command the device reboot, thus connection is lost. Just after this state if I try to reconnect with
rxBledevice
?.establishConnection(false)
?.subscribe({/**/},{/**/})
raise the error BleAlreadyConnectedException
Then, if I send any command to the device, for example with
rxBleConnection
?.writeCharacteristic(UUID, ba)
?.subscribe({/**/},{/**/})
raise the error, BleDisconnectedException.
I try to Dispose the connection observer but nothing changed. The only way (not acceptable) is to restart the app after the BleDevice reboot and disconnect.
If it can help, I also got these logs:
E/BLE: write control OTA failed : com.polidea.rxandroidble2.exceptions.BleGattCallbackTimeoutException: GATT exception from MAC address 00:0B:57:4C:6C:9B, with type BleGattOperation{description='CHARACTERISTIC_WRITE'}
D/BluetoothGatt: onClientConnectionState() - status=22 clientIf=7 device=00:0B:57:4C:6C:XX
E/BLE: error connection BLE Disconnected from 00:0B:57:4C:6C:9B with status 22 (UNKNOWN)
Do you have an idea of what I'm doing wrong?
Thank you.

You're probably not disposing the previousRxBleConnectionsubscription but it cannot be confirmed as you have not shown any relevant code.

did you ever figure this out? I have a similar problem where I connect then the peripheral throws an GATT_ERROR and the error leg of my connection is executed. I can't figure out how to recover from this gracefully.
