Module status indicator output pin, high level output, connect the resistor in series when connecting the LED.
Before connecting,
Flashes when the host does not record the slave address;
When the host records the slave address, it flashes slowly;
The slave flashes quickly.
After the connection, the LED flashes and stops.
Set the high KEY pin to power on the module and enter the AT command mode. The baud rate is fixed at 38400.
LED lights up 1 second every 2 seconds

The module is connected to the indicator output pin, which is a high level output. When connecting the LED, connect the resistor in series.
Before the connection, the lamp pin is output at a constant low level. (LED off)
After the connection, the lamp pin is always at a high level. (LED lights are always on)

Input pin, internal pull down. This pin is tied high, the module enters AT command mode, and the host is used to clear the recorded slave address.
