5.12 Air configuration
The module supports the air configuration function. After the Bluetooth connection is established in the slave state, the host can
access the "BLE DATA CONFIG" feature value under the transparent transmission service (FFF0). The configuration steps are as
follows:
1）、In the air configuration login authentication, send the command <PWDXXXXXX>, where XXXXXX is the login password,
the default is 123456, and return <OK> after success.
2）、The parameter configuration is executed, and the command is consistent with the serial port configuration command.
3）、Disconnect the Bluetooth connection.
Description：
1）、After the <PWDXXXXXX> command fails, the current login status will be exited immediately. That is, the configuration
operation needs to be resumed after the login is successful.。
2）、After the <RESTORE> command is executed, the login password is restored to the default settings.
