the serial adapter can be used regularly.
Note: Do not set the parameters often, or it will damage the chip.
Description: This RS232 serial adapter can be customized according to user requirements
10. AT command
Do not use "Configuration Tools" and the parameters of the RS232 adapter can also be
Inquired / changed when send the AT command with serial port directly.
Note: being the same as using Configuration Tools, it can be allowed to perform
parameter setting command only when the serial adapter working under the "parameter
setting state" (that is press Cmd button to enter). When Parameters are modified, you
should make the serial adapter return to the data model, and then parameter settings take
effect.
Each command must make the two bytes (\r\n)carriage return and line feed ((ASCII codes
are 0x0D, 0x0A) as the end sign, or command can not be identified
The brackets "<>"outside of the parameter is added for convenient reading and the actual
command is without the “<>"

None
2. Set / Inquire the baud rate
command

parameter
AT+BAUD=<rate>\r\n
\r\nOK\r\n
rate: Baud Rate (1200,
2400, 4800, 9600, 19200,
38400, 57600, 115200,
230400, 460800, 921600,
1382400)
Default: 9600
AT+BAUD?\r\n
\r\nOK\r\n
\r\n＋BAUD: <rate>\r\n
Note: This parameter is only valid for the Bluetooth data communication. The baud rate used to set
the parameters is always 9600bps and does not change. The high the baud rate is, the more power
consumption the system uses up.
3. Set / Inquire the serial communication mode
