esp32-wifi

Docs:

this component constitutes some wrappers for the example wifi connections from esp-idf

see the esp-idf examples for more detail

how to use project

1. run git submodule add git@github.com:wolffshots/esp32-wifi.git components/esp32-wifi in your main project
2. configuration of this component is required to choose one of the two modes and set the ssid, password and other wifi settings
   1. station mode - this is when the esp32 acts as a client on another wifi network and receives an ip and is accessible through that network
   2. softap mode - this is when the esp32 acts as a router and broadcasts its own wifi network
3. #include "wifi_sta.h" or #include "wifi_sap.h" should give you access to the wifi station or wifi soft ap parts of this component respectively.

a typical use case would look like the following if you support both modes:

#include "sdkconfig.h"
#ifdef CONFIG_ESP_ENABLE_WIFI_STA
#include "wifi_sta.h"
#endif
#ifdef CONFIG_ESP_ENABLE_WIFI_SOFTAP
#include "wifi_sap.h"
#endif
// function definitions and other imports
void app_main(void)
{
    // start of your main method code
#if defined(CONFIG_ESP_ENABLE_WIFI) && defined(CONFIG_ESP_ENABLE_WIFI_STA)
    wifi_init_sta();
#endif
#if defined(CONFIG_ESP_ENABLE_WIFI) && defined(CONFIG_ESP_ENABLE_WIFI_SOFTAP)
    wifi_init_sap();
#endif
    // rest of your main method code
}

if the above steps don't work then you may need to run git submodule init components/esp32-wifi and then git submodule update --remote --recursive in your main project

folder contents

the component esp32-wifi contains two source files in C language wifi_sta.c and wifi_sap.c. the files are located in root folder.

esp-idf projects are build using cmake. the project build configuration is contained in CMakeLists.txt files that provide set of directives and instructions describing the project's source files and targets (executable, library, or both).

below is short explanation of remaining files in the project folder.

│   └── wifi_sta.h              the header file which describes functions for setting up wifi in station mode
├── .gitignore                  describes what files and folders git should ignore
