wpa2-enterprise does not work in recent versions. #1618

Closed vitcon-iot closed 6 years ago

vitcon-iot commented 6 years ago

Hardware:

Board: ESP32 Dev Module Core Installation/update date: 10/jul/2018 IDE name: Arduino IDE Flash Frequency: 80Mhz Upload Speed: 921600

Description:

The wpa2 enterprise feature is not working after the last update. Calling esp_wifi_sta_wpa2_ent_enable() before calling WiFi.mode() occurs Guru Meditation Error.

Sketch:

#include "esp_wpa2.h"
#include "esp_log.h"
#include <WiFi.h>

const char* ssid = "EngineeringBay"; // your ssid
#define EAP_ID "user1"
#define EAP_USERNAME "user1"
#define EAP_PASSWORD "pass1"

void setup() {
  esp_log_level_set("*", ESP_LOG_VERBOSE);
  Serial.begin(115200);
  delay(10);

  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);

  // WPA2 enterprise magic starts here
  WiFi.disconnect(true);

  int err = 0;
  /*
    esp_wifi_sta_wpa2_ent_clear_ca_cert();
    esp_wifi_sta_wpa2_ent_clear_cert_key();
    esp_wifi_sta_wpa2_ent_set_disable_time_check(true);
  */
  err = esp_wifi_sta_wpa2_ent_set_identity((uint8_t *)EAP_ID, strlen(EAP_ID));
  err = esp_wifi_sta_wpa2_ent_set_username((uint8_t *)EAP_USERNAME, strlen(EAP_USERNAME));
  err = esp_wifi_sta_wpa2_ent_set_password((uint8_t *)EAP_PASSWORD, strlen(EAP_PASSWORD));

  esp_wpa2_config_t config = WPA2_CONFIG_INIT_DEFAULT();
  err = esp_wifi_sta_wpa2_ent_enable(&config);

  // WPA2 enterprise magic ends here

  WiFi.begin(ssid);
  WiFi.mode(WIFI_STA); //call after esp_wifi_sta_wpa2_ent_enable()
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
  //Do nothing.
}

In previous versions of the core in a different PC, both sketch is connected to the AP. (Installed on June 8, 2018) Can I get help with this issue?

WiFi.mode() is now required in order to init the hardware (before it was initing even if WiFi is off and you call disconnect). So that part of the code is fine ;) you need to turn on the radio to use it. As for WPA2-Ent I advise you to file an issue in IDF's repository (that is where devs that deal with the stack are looking)
