Some mobile phone (Nokia 5230) have possibility emulate virtual com-port (in Windows) after connection to PC via bluetooth;usually this com-port use like modem I have to developed bluetooth device (bcm20737) should be detected by standard Windows tools as an emulated com-port (COM3 ect), with which any program can work as with a normal COM port. Data, that will be sent from the PC (via new virtual com-port), will be transferred to UART bcm20737.
If it is possible - how to create custom GATT service?
