Control the LED lights on and off by inputting LED_ON and LED_OFF respectively
wiring:
The positive electrode of the LED is connected to positive electricity, and the negative electrode is connected to GPIOA_Pin1
Bluetooth module TXD is connected to GPIOA_Pin3, VCC is connected to positive power, and GND is connected to negative power.
Note: USART2 is an APB1 peripheral, and Chinese characters occupy twice as many bytes as characters
use:
When the mobile phone transmits “LED_ON” to Bluetooth, the LED light turns on; otherwise, when it transmits “LED_OFF”, the LED light goes out.
