ESP32 Forum

I am having a lot of trouble removing WiFi from my project. I loaded the simple blink sketch, but it keeps including WiFi components, increasing compile time and I assume also the app size, with things such as wpa_supplicant.

There is no off switch in menuconfig nor the "SDK Configuration Editor" in Visual Studio Code's ESP-IDF extension, unlike Bluetooth for which it is extremely obvious and easy.

I tried setting all instances of 'CONFIG_SOC_WIFI_SUPPORTED=y' to 'CONFIG_SOC_WIFI_SUPPORTED=n' and 'CONFIG_ESP_WIFI_ENABLED=y' to 'CONFIG_ESP_WIFI_ENABLED=n' in the file "/sdkconfig" in the root directory of the example project, and tried setting the bools in "/build/config/sdkconfig.json" to false, but the values in both files are always replaced to the enabled state, I don't know why.

I cannot find any resource on not including WiFi in the binary, only posts saying to include WiFi and then disable it with : https://esp32.com/viewtopic.php?t=25515
and unanswered questions from 6 years ago: https://esp32.com/viewtopic.php?t=5211

Please could somebody advise?

A lot of IDF code/components are built/compiled automatically in every IDF project build. While this indeed increases the build time, unused code may be compiled but is usually not linked into the final binary.

please as well don't forget that there are hardware components other then the plain processor involved which require a defined status like the radio PHY on the ESP.
If your project does not require any of these features you should consider to use another processor family.
