DTM - ble_dtm_init

Function packet format

Frame format encoding of the ble_dtm_init packet.

The ble_dtm_init is encoded without an operation code byte. The packet contains only DTM UART configuration (TX pin, RX pin, and baud rate).

The order of the encoding is:

Length Parameter Value
1 byte UART TX DTM UART transmit pin.
1 byte UART RX DTM UART receive pin.
1 byte UART Baudrate DTM UART baud rate.
