WiFiCredentials class

WiFiCredentials

This class allows to define WiFi credentials that can be passed to WiFi.setCredentials() function.

// EXAMPLE - defining and using WiFiCredentials class

void setup() {
    // Ensure that WiFi module is on
    WiFi.on();
    // Set up WPA2 access point "My AP" with password "mypassword" and AES cipher
    WiFiCredentials credentials("My AP", WPA2);
    credentials.setPassword("mypassword")
               .setCipher(WLAN_CIPHER_AES);
    // Connect if settings were successfully saved
    if (WiFi.setCredentials(credentials)) {
        WiFi.connect();
        waitFor(WiFi.ready, 30000);
        Particle.connect();
        waitFor(Particle.connected, 30000);
    }
}

void loop() {
}

WiFiCredentials()

Constructs an instance of the WiFiCredentials class. By default security type is initialized to unsecured (UNSEC).

// SYNTAX
WiFiCredentials credentials(SecurityType security = UNSEC); // 1
WiFiCredentials credentials(const char* ssid, SecurityType security = UNSEC); // 2

// EXAMPLE - constructing WiFiCredentials instance
// Empty instance, security is set to UNSEC
WiFiCredentials credentials;
// No SSID, security is set to WPA2
WiFiCredentials credentials(WPA2);
// SSID set to "My AP", security is set to UNSEC
WiFiCredentials credentials("My AP");
// SSID set to "My WPA AP", security is set to WPA
WiFiCredentials credentials("My AP", WPA);

Parameters:

setSsid()

WiFiCredentials::setSsid, setSsid, WiFiCredentials.setSsid

Sets access point SSID.

// SYNTAX
WiFiCredentials& WiFiCredentials::setSsid(const char* ssid);

// EXAMPLE - setting ssid

Parameters:

  • ssid: SSID (string)

setSecurity()

WiFiCredentials::setSecurity, setSecurity, WiFiCredentials.setSecurity

Sets access point security type.

// SYNTAX
