UART Interface
Main UART Interface:
When used for AT command
communication and data
transmission, the module is in
auto-baud mode by default, where
the UART port automatically
synchronizes within 115200 bps
its baud rate with that of the MCU,
which has to keep sending AT
commands to the module during
the baud rate synchronization
process until OK is returned
indicating a successful
synchronization. After the module
is woken up from Deep Sleep
mode, its UART automatically
uses the previously synchronized
baud rate.
When used for firmware upgrade,
Main UART interface:
When used for AT command
communication and data
transmission, support baud
rates 2400 bps, 4800 bps, 9600
bps, 19200 bps, 38400 bps,
57600 bps, 115200 bps
(default), 230400 bps, and
460800 bps.
When used for firmware
upgrade, support baud rate
921600 bps (default).
Debug UART interface:
Used for debugging and the
baud rate is 6 Mbps.
Signal level: 1.8/3.3 V
