Serial Port Control Commands



Automatic detection of the baud rate is not supported at present. Therefore, the first
returned parameter list is blank when the test command is executed. For example:
+IPR:(),(300,600,1200,2400,4800,9600,19200,38400,57600,115200,230400)



If the physical serial port baud rate is higher than the radio bearer rate, data may be lost
when being transmitted.



After the baud rate is changed, wait for a period of time (for example, 100 ms) before
continuing the communication.

5.5.3 Parameter Description

<rate>: Specifies the baud rate. It is a decimal integer. The values are as follows:

300,600,1200,2400,4800,9600,19200,38400,57600,115200,230400

AT+IPR without a parameter is equivalent to AT+IPR=115200.
