gpy bluetooth not advertising after client disconnect

[neelb]

I've got bluetooth working and sending data from the board to an iPhone and back, but if the app closes and opens again it is unable to find the board again unless I send a Bluetooth().advertise([True]) command via the debug console. What is the right way to have the board re-connect to a client after it gets disconnected?

I also notice that my call back doesn't always get called when the app exits:

bluetooth.callback(trigger=Bluetooth.CLIENT_CONNECTED | Bluetooth.CLIENT_DISCONNECTED, handler=conn_cb)

def conn_cb (bt_o):
    events = bt_o.events()
    if  events & Bluetooth.CLIENT_CONNECTED:
        print("Client connected")
    elif events & Bluetooth.CLIENT_DISCONNECTED:
        print("Client disconnected")
        bt_o.advertise([True]) #Added this to try to fix disconnect issue
