10.1.4+CBAUD, Baud Rate Regulation
This command sets the uniquely UART baud rate. The baud rate of the Module is changed/set to the
request value <rate> written in the command.
Specifying a value of 0 allows operation only at rates automatically detectable by the Module. The
specified rate takes effect following the issuing of any result code(s) associated with the current command
line.
Note: ATZ command sets the Module to default baud rate - Auto baud rate. The auto baud rate can
support 9600, 14400, 19200, 57600, 115200 and 230400.
After sent any AT command, the module will lock on single baud rate. Read command can feedback the
currently baud rate. The module cannot re-auto baud without send AT+CBAUD=0command or re-power
up. The parameter can’t be saved after power up.
