4.6 Configuration
There are two configuration modes: serial port configuration and air configuration. They are basically the same. Before the air
configuration, the authentication password AT+AUTH=123456 must be passed. Once it is passed, the module is allowed to use the air
configuration. The authentication period is the current connection. When disconnected and reconnected, it needs to be re-authenticated.
The module is in configuration mode before the connection is established. The Mod pin is invalid.
After the connection is successful, it is determined whether the module is currently in the configuration mode or the data
transmission mode according to the mod pin level. When mod is high, it is the data transfer mode, and when it is low, it is the
configuration mode.
The Mod pin latches the current state when a valid change is detected. Each state change hold time is valid for at least 200ms.
The Mod pin has no effect on the air configuration.
In configuration mode, the mster sends data to “MAST CHANNEL” and the slave returns “CONFIG BUSY” via “SLAVE
CHANNEL”.
4.7 Data indication
When data is output through the serial port, the DATA pin is set to low level, indicating that data is being transmitted. The AT
command response does not change the state of the DATA pin.
Data output delay is enabled via with AT+DATALY=1. After it is turned on, the module first pulls the DATA pin and outputs the
data after 10ms.

No delay of data output
