aioble handle random disconnection

[puppet13th]

I have been handling random ble disconnection using this method, when running ble as central:

try:
    async with await device.connect() as connection:
        do something...
        
except asyncio.TimeoutError:
    handle connect TimeoutError

except aioble.DeviceDisconnectedError:
    handle disconnected error

except OSError as exc:
    if exc.args == -128:
        handle disconnected error
    else:
        raise

sometime there is message in repl something like this:
[aioble] E: Disconnect -128

should aioble raise aioble.DeviceDisconnectedError instead of OSError( -128 )?

Have you found the reason of this Error?
