title: Are there native APIs for communication over Bluetooth in Android?if so where do i find the documentaion?
body: <p>I have a C++ library which helps in establishing communication to a POS terminal over LAN and serial port, now i want this library to work on android phone only over Bluetooth medium,</p>
  
  <p>If there are native APIs for Bluetooth communication in android, I can port this c++ library to android and write a java application which will use this library through JNI</p>
