INTEGRATION¶

Introduction¶

Note

In this section, we introduce how to integrate the wifi driver into the project.

Danger

For testing convenience in campus network environments, the wifi used in this project is enterprise WiFi, which requires WPA2 Enterprise mode and PEAP-MSCHAPV2 authentication. If you need to connect to a regular WiFi network (such as home WiFi), please implement it separately.

Create a New Component¶

Warning

Before you create a component in the driver directory, make sure you have incorporated the driver directory into the project by adding the path to the driver directory to the EXTRA_COMPONENT_DIRS variable in the project-level CMakeLists.txt file.

Open the project in VSCode, open the integrated terminal, and type in

get_idf

to actiate the ESP-IDF environment. Then type in the following command to create a new component named node_wifi:

idf.py -C driver create-component node_wifi

The command above means to create a new component named node_wifi in the driver directory. After executing the command, you will see a new directory named node_wifi in the driver directory. And the command will automatically generate the CMakeLists.txt file for the new component, as well as the node_wifi.h and node_wifi.c files.

Alternatively, you can mannually create the node_wifi directory in the driver directory, and then create the CMakeLists.txt, node_wifi.h, and node_wifi.c files in the node_wifi directory.

Replace the Code¶

Component Level

Replace the code in this section into the CMakelists.txt, node_wifi.h, and node_wifi.c files under the component.

Project Level

Replace the code in main.c/cpp with the corresponding code. No need to change the CMakeLists.txt file at the project level.

Compile and Flash the Project¶

Open the project in VSCode, open the integrated terminal, and type in

idf.py build flash monitor

Now, you will see random numbers from the serial monitor.
