Homemade bluetooth mobile app to control stm8/stm32/C51 onboard LED

Let's share here, self-made mobile app to control the LED on the microcontroller to realize the communication between the upper computer and the lower computer

This time I share the bluetooth app to control stm8, stm32, and C51. I have shared it in the previous article. If you don’t understand, you can read it –>Portal
The principle is very simple, that is, the Bluetooth mobile app sends character 1 (on), character 2 (off)p>

The production of the bluetooth app looks at the portal above me, nothing has changed here

The code here is based on the stm8s serial port communication code. If there is no code, you can read my last article->Portal

In fact, these are very simple, just look at the code below.

What could be simpler?no more

We click forward and backward on the mobile phone (this is an app made by a bluetooth car before, I am too lazy to change it)
Forward - send character 1
Back - send character 2
So it will beTurn on the LED and see the picture below

before the button was clicked

After clicking the button

The serial assistant is informative

In this way, the operation of Bluetooth control stm8 is realized, is it very simple?
