    send: avoid BT restart when back has been pressed
    
    The function _restart_bluetooth can be called after a transfer ends or
    after the user presses the back button (and triggers the closing of the
    BT socket).
    
    If the back button has been pressed we don't want to restart the
    Bluetooth service.
