- Thu Oct 17, 2019 12:53 am #84196 Hello,

it seems that EAP-TLS, which is officially supported, is pretty rarely used. I hardly find any documentation on the web. The following code crashes the ESP8266MOD for unknown reasons - at least unknown to me:

Code: Select all
 wifi_set_opmode(STATION_MODE);

  struct station_config wifi_config;
  memset(&wifi_config, 0, sizeof(wifi_config));
  strcpy((char*)wifi_config.ssid, ssid);
  wifi_station_set_config(&wifi_config);

  wifi_station_clear_cert_key();
  wifi_station_clear_enterprise_ca_cert();
  wifi_station_clear_enterprise_identity();
  wifi_station_clear_enterprise_username();
  wifi_station_clear_enterprise_password();
  wifi_station_clear_enterprise_new_password();
 
 
  wifi_station_set_wpa2_enterprise_auth(1);
  wifi_station_set_enterprise_username((uint8*)identity, strlen(identity));
 
  wifi_station_clear_enterprise_cert_key();
  wifi_station_set_enterprise_cert_key(esp8266_crt, esp8266_crt_len, esp8266_key, esp8266_key_len, NULL, 0);


  wifi_station_connect();




It fails with:

Any ideas?

Thanks alot for your help!

- Thu Oct 17, 2019 3:39 pm #84210 The code above connects to the Radius server and sends EAP Identity (1) as the authentication type. For EAP-TLS, it should be the value 13. I have not found out how to configure the system to really use EAP-TLS.

For me, wifi enterprise never work if I enable "Debug".
However, I'm facing some issue with it and I also need to enable "Debug"
