Using USB connection for serial port communication

Hi,

I would use the RePhone USB connection to read/write data in a serial communication. In the examples provided in the LINKIT_ASSIST_SDK there is an example which use the pins D8/D9 but no one that use the USB connection.

Does any one can help me?

Thanks!
