bluetoothpn.cxx

linux系统下的关于蓝牙模块的源代码！十分的经典的程序！

//
// BluePN.cxx
// This file contains code that implements an fltk-based Bluetooth
// Piconet Neighborhood.  What a user will see is a window with a tree
// view that locates every Bluetooth-enabled device.  Each bluetooth
// device will be queried for services and attributes for those services
// using SDP.  This UI is tied to the Axis Bluetooth stack simply by
// ioctl() calls.
//
// This UI was created by a combination of fluid generated window and menu
// design + the Fl_Toggle_Tree widget.
