TestDBTClientServer00.java

Unit test, trial using actual BT adapter.

Unit test, trial using actual BT adapter.Basic client and server Bluetooth tests, requiring one BT adapter:

• start server advertising
• server stop advertising
• reuse server-adapter for client-mode discovery (just toggle on/off)
