Arduino portenta H7 connect Wifi with WPA2-Enterprise mode

Official Hardware Portenta Family Portenta H7

I am currently using arduino portenta H7, want to connect to Wifi network with WPA2-Enterprise mode. I have searched many documents and sample codes to try but cannot connect. Please help me!

Hi, WPA2-Enterprise differs from the standard WPA2-Personal primarily because it uses individual username and password credentials for each user instead of a single shared password, requiring an external authentication server like RADIUS and implementing the Extensible Authentication Protocol framework with methods such as PEAP, TLS, or TTLS while in the code, this difference is clearly visible as WPA2-Personal simply uses WiFi.begin(ssid, password) whereas WPA2-Enterprise requires more complex configuration with WiFi.beginEnterprise(ssid, identity, password) followed by specifying the EAP method and Phase 2 authentication with WiFi.enterpriseSetMethod(eap_method) and WiFi.enterpriseSetPhase2(phase2_authentication), and in some cases may even require additional certificate configuration through methods like WiFi.enterpriseSetCACert() which altogether creates a more sophisticated but more secure network access control system compared to the simpler but less secure WPA2-Personal approach.

#include <WiFi.h>
#include <WiFiClient.h>

// WPA2-Enterprise Network Configuration
const char* ssid = "enterprise_network_name";    // Network name
const char* identity = "your_username";          // Your username/identity
const char* password = "your_password";          // Your password
const char* eap_method = "PEAP";                 // EAP method (PEAP, TLS, TTLS)
const char* phase2_authentication = "MSCHAPV2";  // Phase 2 authentication (GTC, MSCHAPV2)

// Server variables (example)
const char* serverAddress = "192.168.1.100";
int serverPort = 8080;
WiFiClient client;

void setup() {
  // Initialize serial communication
  Serial.begin(115200);
  delay(1000);
  Serial.println("Arduino Portenta H7 - WPA2-Enterprise Example");
  
  // Configure WiFi pins if needed (may not be necessary on Portenta H7)
  // pinMode(LED_BUILTIN, OUTPUT);
  
  // Start WiFi connection
  Serial.print("Connecting to ");
  Serial.println(ssid);
  
  // Set WPA2-Enterprise credentials
  WiFi.beginEnterprise(ssid, identity, password);
  
  // Additional configuration for WPA2-Enterprise
  WiFi.enterpriseSetMethod(eap_method);
  WiFi.enterpriseSetPhase2(phase2_authentication);
  
  // Wait for connection
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  
  // Display connection information
  Serial.println();
  Serial.println("WiFi connected!");
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());
  Serial.print("Subnet Mask: ");
  Serial.println(WiFi.subnetMask());
  Serial.print("Gateway IP: ");
  Serial.println(WiFi.gatewayIP());
  Serial.print("DNS IP: ");
  Serial.println(WiFi.dnsIP());
  Serial.print("Signal strength (RSSI): ");
  Serial.print(WiFi.RSSI());
  Serial.println(" dBm");
}

void loop() {
  // Check server connection (example usage)
  if (connectToServer()) {
    Serial.println("Connected to server!");
    
    // Send data to server
    sendDataToServer("Hello from Portenta H7!");
    
    // Close the connection
    client.stop();
    Serial.println("Connection closed");
  }
  
  // Periodically check WiFi connection status
  if (WiFi.status() != WL_CONNECTED) {
    Serial.println("WiFi connection lost. Reconnecting...");
    WiFi.reconnect();
  }
  
  delay(10000); // Wait 10 seconds before next attempt
}

// Function to connect to the server
bool connectToServer() {
  Serial.print("Connecting to server ");
  Serial.print(serverAddress);
  Serial.print(":");
  Serial.println(serverPort);
  
  if (client.connect(serverAddress, serverPort)) {
    return true;
  } else {
    Serial.println("Server connection failed");
    return false;
  }
}

// Function to send data to the server
void sendDataToServer(const char* data) {
  client.println(data);
  Serial.print("Data sent: ");
  Serial.println(data);
  
  // Wait for response
  unsigned long timeout = millis();
  while (client.available() == 0) {
    if (millis() - timeout > 5000) {
      Serial.println("Server response timeout");
      return;
    }
  }
  
  // Read the response
  while (client.available()) {
    String line = client.readStringUntil('\r');
    Serial.print("Response from server: ");
    Serial.println(line);
  }
}

I have also tried this code, however the Wifi.h library on Portenta H7 does not support methods such as WiFi.beginEnterprise, WiFi.enterpriseSetMethod... I searched for reference documents and portenta H7 does not support WPA2-Enterprise Wifi connection :((

Thank you for taking the time to support.

I think your options are than limited to:

  1. Use the Portenta H7 with non-enterprise WiFi networks only
  2. Look for alternative hardware that explicitly supports WPA2-Enterprise, such as ESP32-based boards with specialized libraries
  3. Connect the Portenta H7 to a network using ethernet or other connectivity options if available
  4. Check if future firmware updates might add this capability (though there's no guarantee)
  5. Create your own library

Hi @TE_Tatan. I get the feeling your post was generated by an AI. It is OK to use AI-based tools to assist you when providing help here on the forum, but it must be done responsibly.

Just as with any other information you find on the Internet, you must carefully evaluate AI-generated content for accuracy, relevance, and appropriateness within the context. Copy/pasting without giving any thought to the information is irresponsible, regardless of the source of that information. If you are not able to make such an evaluation, then please don't share the content here on the forum.

The fact that you shared code that doesn't even compile makes it seem like you weren't taking enough care to validate the information from the AI. If so, please make a stronger effort in the future.

Thanks in advance for your cooperation.

Hi, thanks for your message and for taking the time to point this out.

Just to clarify: the code I posted wasn’t generated by an AI. It was a quick example I wrote myself, loosely based on a working version, just to illustrate a concept. You’re absolutely right, though — I didn’t test that particular snippet before posting it, and I can see how that could cause confusion or come across as careless.

I really appreciate the reminder, and I’ll make sure to post only fully tested and working code from now on to avoid any misunderstanding.

Thanks again for your feedback

I have switched to using Ethernet connection. Thank you very much!
