Auxiliary Uart Port; Bluetooth Uart Port - Quectel BC950N-N1 Hardware Design

3.8.3. Auxiliary UART Port

The auxiliary UART port is designed as a general purpose UART for communication with DTE. It also
supports log output for firmware debugging, and hardware flow control*. Its baud rate is 115200bps by
default. The following is a reference design of auxiliary UART port.
