Hello everyone! Finally exam-time is over and the fun restarts... I am working on using bluetooth in AutoIt. I wrote the following script to implement BluetoothFindFirstRadio function. (http://msdn.microsoft.com/en-us/library/windows/desktop/aa362786(v=vs.85).aspx) #include <WinAPI.au3> Global $phRadio $BLUETOOTH_FIND_RADIO_PARAMS = DllStructCreate('DWORD') DllStructSetData($BLUETOOTH_FIND_RADIO_PARAMS, 1 , DllStructGetSize($BLUETOOTH_FIND_RADIO_PARAMS)) $RESULT = DllCall("bthprops.cpl"
