Host Interface
8.1 UART
The BGM111 can be controlled over the UART interface as a peripheral to an external processor. In order for the communication to be
reliable, hardware flow control signals (RTS and CTS) must be present between the host and the module. For baud rates exceeding
115.200 kbps the controlling processor should have a clock frequency accurate to within 1% in order for the UART signaling to work
reliably.
