Configure
The module supports two configuration methods: serial configuration and over-the-air configuration. These two
configuration modes are basically the same, before the air configuration must be through the AT + AUTH = 123456
authentication password, i.e., to the remote configuration service UUID input 123456, the module is allowed to use the
air configuration after the authentication is passed. The authentication period for over-the-air configuration is the current
connection, and if the device is disconnected and reconnected, it needs to be re-authenticated.
After the module is in the wake-up state, it is in the configuration mode by default, and can be configured directly
through the AT command.
