Disconnect

Pin	Status	Description
Pin 15	High Level	Disconnect Bluetooth connection

Note：

To use this function, the pin function must be enabled using the AT+PIOCFG command.

Working Mode

Throughput Mode

• Bluetooth Not Connected: Data received via UART is parsed as AT commands.

• Bluetooth Connected: All data received via UART is sent as-is to the remote Bluetooth device.

Command Mode

• Bluetooth Not Connected: Data received via UART is parsed as AT commands.

• Bluetooth Connected: Data received via UART is still parsed as AT commands. Data must be sent to the remote device using AT commands, e.g., AT+LESEND.

Low-Power Strategy

Low-Power Mode Setting

Enable or disable the low power function through the command AT+LPM{=Param} .

Low-Power Operation Strategy

• AT+LPM=1: BT UART automatically enters low power mode if no data is received for more than 10 seconds. The first frame of data from the BT UART wakes up the Bluetooth. Once connected, it does not enter low power mode.
