This code sample is named BtSearch. It demonstrates simple Bluetooth device discovery via the WinSock 2 API. The application provides a listbox control which, when searching is complete, lists the discovered Bluetooth devices. Only the names of the mobile devices are displayed, but their addresses are also retrieved. You can use this extra information to query the mobile devices for more information.
