How can I connect to WPA2-Enterprise EAP-TLS by ESP8266MOD?
Posted: Fri Aug 31, 2018 2:24 amHi everyone,
I have a troubles with getting access to WLAN secured by WPA2-Enterprise EAP-TLS using ESP8266 and Arduino IDE. Is there any solution, to do it?
I have p12 certificate to do connect, so I extracted from it two files privateKey and publicCert and turned both to *.h files. Using joostd's code which can be found here I can't get access to wlan. Even Radius doesn't have any trace of try to connect by my ESP.
But, there is another code which leave a trace on Radius, but Radius shows that "Client doesn't support EAP." I know, that ESP8266 supports eap-tls connection. So, how can I solve this problem? Any solutions? Has anybody solve the same or similar issue?
Here is a code which leave the trace in Radius, but can't get access (I don't know author):
Problem solved!

// Setting ESP into STATION mode only (no AP mode or dual mode)
wifi_set_opmode(STATION_MODE);
struct station_config wifi_config;
memset(&wifi_config, 0, sizeof(wifi_config));
strcpy((char*)wifi_config.ssid, ssid);
strcpy((char*)wifi_config.password, wlpasswd);
wifi_station_set_config(&wifi_config);
wifi_station_set_wpa2_enterprise_auth(1);
// Clean up to be sure no old data is still inside
