Remote Bluetooth

Пытаюсь понять работу клиента -server bluetooth. Где андроид клиент. ПК это сервер.

Я нашел код . Это работало на samsung galaxy 10.1 (android 3.2 ), но не работает на samsung galaxy s (android 2.3.3 )и htc wildfire s (android 2.2 ).

MY_UUID = UUID.fromString("04c6093b-0000-1000-8000-00805f9b34fb");
