Serial adapter can be used regularly.
Note: Do not set the parameters often, or it will damage the chip.
Description: This can be customized according to user requirements
10. AT command
Do not use "Configuration Tools" and the parameters of the 100m RS232 Bluetooth Serial
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 cannot be identified
The brackets "<>"outside of the parameter is added for convenient reading and the actual
command is without the “<>"

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.
