The relevant call in code is in btservice.cpp so ensure you can run bluetoothctl connect as a starting point. It should initiate the connection and then AA on your phone should auto connect to the wifi hotspot you've created. Although joining the wifi hotspot manually won't start AA automatically, it's a good way to test if you have a compatible channel, etc.
