wpa2-enterprise does not work in the last arduino cores #1686

please decode that stack trace :) |
|
ok. Thanks. Decoding stack results |
|
Everyone that tested sketch was able to connect to Eduroam network only or networks under FreeRadius service (for 802.1x - RADIUS server software) under Linux software, most used with Debian. |

Hi,
In previous arduino cores, I could connect without problem to wpa2 enterprise radius network, but with last arduino cores fails the connection with same program.
Is the same problem comented in this issue:
espressif/esp-idf#2181
When I call "WiFi.begin(ssid)" the ESP32 try to connect, but a Stack smashing protect failure error occurs.
I tested it on ESP-WROOM-32 and ESP-WROVER default profile with same result.
Program works great until "2018-06-24 14:59:16" arduino core update. From "2018-06-27 09:06:02" update until the last Arduino core update the program fails with same error.
Analizing the Arduino core code, this error is shown when function "esp_wifi_connect()" is executed inside function:
wl_status_t WiFiSTAClass::begin(const char* ssid, const char passphrase, int32_t channel, const uint8_t bssid, bool connect)
in "WiFiSTA.cpp" file
This is the error message with Backtrace:
Connecting to network: Uni-Net
Mode: STA
Channel: 1
SSID (7): Uni-Net
Passphrase (0):
BSSID set: 0
.
Stack smashing protect failure!
abort() was called at PC 0x400ea028 on core 1
Backtrace: 0x4008f6f4:0x3ffbb6e0 0x4008f8f7:0x3ffbb700 0x400ea028:0x3ffbb720 0x400de649:0x3ffbb740 0x400de6f6:0x3ffbb800 0x400db587:0x3ffbb840 0x400db9c2:0x3ffbb880 0x400da7a9:0x3ffbb8a0 0x400da1cc:0x3ffbb8f0 0x400da239:0x3ffbb930 0x400d8c37:0x3ffbb950 0x400d8e39:0x3ffbb990 0x400d7f8d:0x3ffbb9b0 0x400e79aa:0x3ffbba30 0x400e7c36:0x3ffbba60
Rebooting...
This is my program. It is a modified version of "WiFiClientEnterprise.ino" example from Arduino core:

WiFi.begin(ssid); //connect to Eduroam function
WiFi.setHostname("PINGER"); //set Hostname for your device - not neccesary
while (WiFi.status() != WL_CONNECTED) {

Serial.print(".");
}

Serial.println("");

Serial.println("IP address set: ");
Serial.println(WiFi.localIP()); //print LAN IP
}

if (WiFi.status() != WL_CONNECTED) { //if we lost connection, retry
WiFi.begin(ssid);

}
Serial.print("Connecting to website: ");
Serial.println(host);

Serial.println("Connection lost! - Failed response");
}

unsigned long timeout = millis();
while (client.available() == 0) {

Serial.println("Client timed out! - retry");
}
}
while(client.available()) {
line = client.readStringUntil('\n');
Serial.println(line);
}
Serial.println();
Serial.println("End connection");
client.stop();
}
