Intended Interface for WPA2-Enterprise

[raphaelhetzel]

Do you have an interface in mind for integrating WPA2 Enterprise? In the IDF/driver this is handled using a completely separate API (esp_wifi_sta_wpa2_ent_set_username, esp_wifi_sta_wpa2_ent_enable) but given the way the interface is configured here, I would expect that to happen in the background when using the normal set_configuration method with auth_method set to the enterprise variant.

I guess that would be the way to go, yes

Okay, might try to add this like that then once I find the capacity.

Hi, anyone was able to connect with a WPA2 enterprise network using Rust?

I'm trying with this code, but not luck by now: unsafe { let ret1 = esp_idf_sys::esp_eap_client_set_ca_cert(CA_CERT.as_ptr(), CA_CERT.len() as i32); let ret2 = esp_idf_sys::esp_eap_client_set_identity(EAP_ID.as_ptr(), EAP_ID.len() as i32); let ret3 = esp_idf_sys::esp_eap_client_set_username(EAP_USERNAME.as_ptr(), EAP_USERNAME.len() as i32); let ret4 = esp_idf_sys::esp_eap_client_set_password(EAP_PASSWORD.as_ptr(), EAP_PASSWORD.len() as i32); let ret5 = esp_idf_sys::esp_eap_client_set_certificate_and_key(CLIENT_CERT.as_ptr(), CLIENT_CERT.len() as i32, CLIENT_KEY.as_ptr(), CLIENT_KEY.len() as i32, std::ptr::null(), 0); info!("Wifi Enterprise: {}:{}:{}:{}:{}", ret1, ret2, ret3, ret4, ret5); esp_idf_sys::esp_wifi_sta_enterprise_enable(); }

wifi.set_configuration(&Configuration::Client(
    ClientConfiguration {
        ssid: SSID.try_into().unwrap(),
        password: PASS.try_into().unwrap(),
        auth_method: AuthMethod::WPA2Enterprise,
        channel,
        ..Default::default()
    }
))?;

info!("Connecting wifi...");

wifi.connect()?;

From the code and the logs it seems you are trying to use esp-wifi on esp-idf/Rust std. That's not supported (it's for bare-metal Rust). You probably want to use https://crates.io/crates/esp-idf-svc which offers the same functionality (and more) for Rust-Std on esp-idf

@bjoernQ, I believe that i'm using the esp-idf-svc on esp-idf/Rust std. These are my dependencies:

Esp32:

esp-idf-svc = { version = "0.48", features = ["std"]} esp-idf-hal = { version="0.43.1"} esp-idf-sys = { version = "0.34.1"} embedded-svc = { version = "0.27.1"}

And i am using this crates like this: use esp_idf_svc::wifi::{AuthMethod, AsyncWifi, ClientConfiguration, Configuration, EspWifi}; use esp_idf_hal::peripheral::Peripheral; use esp_idf_svc::timer::{EspTimerService, Task}; use esp_idf_svc::eventloop::EspSystemEventLoop; use esp_idf_svc::ping::EspPing; use esp_idf_svc::nvs::EspNvsPartition; use esp_idf_svc::nvs::NvsDefault;

The problem is that dispate of esp-idf-svc has the auth method WPA2 Enterprise, there are no functions to define the enterprise client, password and certificates. This is why i'm using the esp-idf-sys functions.

let wifi_configuration: Configuration = Configuration::Client(ClientConfiguration {
    ssid: ssid_name,
    auth_method: AuthMethod::WPA2Enterprise,
    ..Default::default()
});

@gustavowd Thanks for clarification. In that case https://github.com/esp-rs/esp-idf-svc would be the correct repository to raise this issue

Whatever their solution will look like might be helpful for esp-wifi however

(Sorry for the noise, I though this was a separate issue :sweat_smile: )
