WPA2 Enterprise not connecting

[gustavowd]

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

I'm trying with this code, but not luck by now:

`
let mut esp_wifi = EspWifi::new(modem, sysloop.clone(), None)?;
let mut wifi = BlockingWifi::wrap(&mut esp_wifi, sysloop)?;

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()?;`

And the full log is:

Any ideas on this issue?

I'm seeing similar behavior. I didn't see it right away, as my main development machine is kept on rustc 1.75.0-nightly (8edb9b87e 2024-01-02), and my secondary machine is at 1.77.0-nightly(424037dcb 2024-03-18).

On the older version, wifi is able to connect without much issue.

On this newer version of rustc, I get the same behavior:

@Paumanok, I don't think that's the case. I can connect to a personal network. My problem is with the WPA2 Enterprise network.
I tried the Rust version 1.75 and I have the same issue.

@Paumanok, I don't think that's the case. I can connect to a personal network. My problem is with the WPA2 Enterprise network. I tried the Rust version 1.75 and I have the same issue.

So I did some more testing after my original response, I was able to connect to my home router's WPA2 network. My issue was in a raspberry pi I've been using as a development network, which it can no longer connect to, which is WPA-PSK.

I was unable to downgrade to 1.75 manually as well, as the 1.75-nightly is no longer available. Standard 1.75 didn't work.

I'm wondering if there was some regression that may have a common cause.

[Paumanok]

Coming back to say, beginner mistake and I didn't downgrade the actual esp toolchain.

going back to 1.75 via

espup uninstall
espup install --toolchain-version 1.75.0.0

Fixed my wifi connection for now, but the issue is still there with 1.77

did you do your test always with a debug build or did you build with --release. Its unlikely that there is something in the compiler itself that is causing it, probably more of a site effect.
