5.5 Configuration
The module supports two configuration methods: serial port configuration and air configuration. The two
configuration methods are basically the same. Before the air configuration, the authentication password of
AT+AUTH=123456 must be passed. After the authentication is passed, the module is allowed to use the air configuration.
The air configuration authentication period is this connection, and re-authentication is required if the device is
disconnected and reconnected.
The module is in configuration mode before the connection is established. The Mod pin is invalid.
After the connection is successful, determine whether the module is currently in configuration mode or data
transmission mode according to the mod pin level. When mod is high, it is data transmission mode, when it is low, it is
configuration mode.
When the Mod pin detects a valid change, the current state is latched. The hold time for each state change is more
than 200ms valid.
The Mod pin does not affect the air configuration.
In configuration mode, the master sends data to “MAST CHANNEL”, and the slave returns “CONFIG BUSY”
through “SLAVE CHANNEL”.
5.6 Data indication
When the module outputs data through the serial port, the module sets the DATA pin to low level, indicating that
data is being sent. AT command response does not change the DATA pin state.
The module can turn on the data output delay through AT+DATALY=1. After the data output delay is turned on, the
module first pulls the DATA pin and outputs data after 10ms.
