878
main parameters: COM baud rate and verify，RF baud rate, Channel and frequency。
You can change these parameters by our RF Module software. When RF baudrate is
faster than COM baudrate，One frame Can transmit limitless data. When RF baudrate is not faster than
COM baudrate ，One frame Can transmit 255 bytes. You can set the rate according your request.
