I am using RFComm with the SPP. The device is a BT to serial module attached to a microcontroller that I also programmed. It sends a packet of 17 characters about 3 times a second. The device is identified by pairing first in the Settings app, then enumerating bonded devices in my app and letting the user select the appropriate device from a spinner. The socket is created with rfcomm and the UUID for SPP.
After looking at this more closely I realized that what I want to do really should be done in a service, not in an activity. So I am going to rewrite my BT functionality into a local service that binds to an activity.
