Command
Query Command:
AT+UART?
Set Command:
AT+UART=<baudrate>,<databits>,<stopbits
>,<parity>,<flow󰐇control>
Response
+UART:<baudrate>,<databits>,<stopbits>,<parity>,
<flow󰐇control>
OK
OK
Note
Command AT+UART? will return the actual value of UART
configuration parameters, which may have allowable
errors compared with the set value.
For example, if the UART baud rate is set as 115200,
the baud rate returned by using command AT+UART?
could be 115273.
