ESP8266WiFi module (IoT switch) test (AP mode) [Copy link]

 

The Internet of Things is very popular nowadays, so let’s get two ESP8266WiFi modules to experience the fun of network control.

one,

I use an 8-pin WiFi module, as shown below:

The pin diagram of the module is as follows:

Note on pin usage: the module is powered by 3.3V, the CH_PD pin is pulled high, and GPIO15 (this step can be ignored in systems without GPIO15 pin) is pulled low, and the system can start. For this purpose, I designed a special test board. The schematic diagram, 3D diagram and engineering files of the test board are as follows:

two,

Finally, a finished product was welded. Welding patches is a technical job.

After testing, there is no problem with the board hardware

three,

Start writing the program. AP mode means that the WiFi module itself sends out a hotspot, and the mobile phone connects to the hotspot of the WiFi module for data communication. The AP mode program runs in Keil5. Program project file: 物联网WiFi开关（AP模式）.rar (4.38 MB, downloads: 48)

Users can modify the test.c and test.h files according to their needs. I will pull out the codes in these two files for explanation.

First configure the working mode AP mode: ESP8266_Net_Mode_Choose (AP);

For details, please look at the code or leave me a message, and I will answer you in detail. Finally, use the SWD interface to download the program.

Four,

Connect the circuit and start testing.

ESP8266 is cheaper, ESP32 is more powerful
