Frantisek Hrbata 1c92945f59 change(examples): switch examples to use a minimal build 
Currently, several example dependencies rely on the fact that all
registered components are added to the build, along with components
specified in common requirements. This results in longer build times
because even unused components must be built. Switch all examples to use
idf_minimal_build to compile only the components actually required by
the example.

Supported Targets ESP32 ESP32-C2 ESP32-C3 ESP32-C5 ESP32-C6 ESP32-C61 ESP32-S2 ESP32-S3

WPA2 Enterprise Example

This example shows how ESP32 connects to AP with Wi-Fi enterprise encryption using the EAP-FAST method. The example does the following steps:

  1. Install CA certificate which is optional.
  2. Set user name and password and identity.
  3. Set the PAC file which may be empty.
  4. Enable WiFi enterprise mode.
  5. Connect to AP.

Note:

  1. EAP-FAST is not supported with CONFIG_ESP_WIFI_MBEDTLS_TLS_CLIENT and so is disabled by default.
  2. Setting the config fast_provisioning to methods 0 and 1 do not support saving the PAC credentials in case of a restart or loss of power.
  3. The certificates present in the examples/wifi/wifi_eap_fast/main folder contain server certificates which have the corresponding CA as well. These can be used for server validation which is opptional.
  4. The expiration date of these certificates is 2027/06/05.

Configuration

idf.py menuconfig
  • Set SSID of Access Point to connect in Example Configuration.
  • Enter EAP-ID.
  • Enter Username and Password.
  • Enable or disable Validate Server option.

Build and Flash the project.

idf.py -p PORT flash monitor
