3.2 UART and SPI Interface

The module provides one 2-wire UART interface. As the UART interface supports signal control through
standard modem handshake, Software commands are entered and serial communication is performed through the
UART interface.
The baud rates supported are shown below: 300 bps, 600 bps, 1200 bps, 2400 bps, 4800 bps, 9600 bps, 19200 bps,
38400 bps, 57600 bps, 115200 bps, 230400 bps, 460800 bps, 921600 bps, 2764800 bps.
