问题
Is it possible to make a loopback Bluetooth connection in an Android phone so that one service can connect to another within the same phone (or even to itself)?
The idea is to use it so I can test a multi-player game that uses Bluetooth to communicate between players.

No it is not possible for bluetooth services to connect to itself or other services on the same phone.
