# 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 wpa2 enterprise.
|
|
5. Connect to AP.
|
|
|
|
*Note:* 1. EAP-FAST is not supported with `CONFIG_WPA_MBEDTLS_CRYPTO` 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
|
|
```
|
|
|
|
