HC-05 Bluetooth serial communication module should be one of the most widely used Bluetooth modules. Because the HC05 module is a high-performance master-slave integrated Bluetooth serial port module, you can get started without knowing too much Bluetooth-related knowledge. To put it bluntly, it's just a Bluetooth-to-serial device. As long as you know how to program and use the serial port, you can realize the so-called transparent transmission (transparent transmission).
In this article, the Bluetooth module is used to realize the function of mobile phone Bluetooth control STM32 chip.
1. The debugging of the Bluetooth module
needs to be improved
Two, mobile phone Bluetooth control STM32 single-chip microcomputer
Realization function: The mobile phone sends a message to the STM32 single-chip microcomputer via Bluetooth, and the STM32 returns the message to the mobile phone unchanged after receiving the message. Of course, if you master this example, you can also modify it to send a specific message from the mobile phone, and then the STM32 microcontroller makes the corresponding action. For example: lighting LEDs, etc., starting motors, etc.
