I'm using Python and the provided PyBluez for some experiments with Bluetooth. I can execute the Python script on the device from my PC, via ssh. As far as I can see, it seems that the bluetooth module stops working when the n770's screen switches off: is it normal? can I avoid this behaviour? I've not yet tried to start a real communication with a bluetooth device, so: starting a Bluetooth communication, will it hang/stop when the screen switches off?
