Hello.

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?

As btta​ 's suggestion, CYW20706 should meet your requirements.

The SPP profile is used to replace the COM line with bluetooth. The classical bluetooth support the SPP profile  while BLE not.

The bcm20737 is BLE only. The CYW20706/20719 support BR/EDR/BLE both.

You may want to look at CYW20706 (BT/BLE) in our sister forum instead (WICED Studio Bluetooth Forums) I think there is a spp app in the wiced studio sdk on this device.
