I need to build a simple Android app that communicates over a bluetooth serial line

[G+_Mike Meyer]

I need to build a simple Android app that communicates over a bluetooth serial line. Looks like SL4A/QPython3/... should be able to do it - there's a bluetooth_chat.py in most of the Python for Android distributions. But when it should open a list of bluetooth devices to connect to, it just exits the script with no indication of what went wrong.

 

Anyone got any hints as to how I might figure out what's going wrong here?
