WiFi
WiFiCredentials class
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:
ssid: SSID (string)security: see SecurityType enum.
setSsid()
WiFiCredentials::setSsid, setSsid, WiFiCredentials.setSsid
Sets access point SSID.
// SYNTAX
WiFiCredentials& WiFiCredentials::setSsid(const char* ssid);
// EXAMPLE - setting ssid
WiFiCredentials credentials;
credentials.setSsid("My AP");
Parameters:
ssid: SSID (string)
setSecurity()
WiFiCredentials::setSecurity, setSecurity, WiFiCredentials.setSecurity
Sets access point security type.
// SYNTAX
WiFiCredentials& WiFiCredentials::setSecurity(SecurityType security);
// EXAMPLE - setting security type
WiFiCredentials credentials;
credentials.setSecurity(WPA2);
Parameters:
security: see SecurityType enum.
setCipher()
Sets access point cipher.
// SYNTAX
WiFiCredentials& WiFiCredentials::setCipher(WLanSecurityCipher cipher);
// EXAMPLE - setting cipher
WiFiCredentials credentials;
credentials.setCipher(WLAN_CIPHER_AES);
Parameters:
cipher: see WLanSecurityCipher enum.
setPassword()
WiFiCredentials::setPassword, setPassword, WiFiCredentials.setPassword
Sets access point password.
When configuring credentials for WPA/WPA2 Enterprise access point with PEAP/MSCHAPv2 authentication, this function sets password for username set by setIdentity().
// SYNTAX
WiFiCredentials& WiFiCredentials::setPassword(const char* password);
// EXAMPLE - setting password
WiFiCredentials credentials("My AP", WPA2);
credentials.setPassword("mypassword");
Parameters:
password: WEP/WPA/WPA2 access point password, or user password for PEAP/MSCHAPv2 authentication (string)
The password is limited to 64 7-bit ASCII characters. If you pass in a longer password, only the first 64 characters will be saved.
setChannel()
WiFiCredentials::setChannel, setChannel, WiFiCredentials.setChannel
Sets access point channel.
// SYNYAX
WiFiCredentials& WiFiCredentials::setChannel(int channel);
// EXAMPLE - setting channel
WiFiCredentials credentials("My AP");
credentials.setChannel(10);
Parameters:
channel: WLAN channel (int)
setEapType()
WiFiCredentials::setEapType, setEapType, WiFiCredentials.setEapType
Sets EAP type.
// SYNTAX
WiFiCredentials& WiFiCredentials::setEapType(WLanEapType type);
// EXAMPLE - setting EAP type
WiFiCredentials credentials("My Enterprise AP", WPA2_ENTERPRISE);
credentials.setEapType(WLAN_EAP_TYPE_PEAP);
Parameters:
type: EAP type. See WLanEapType enum for a list of supported values.
This is a feature of WPA Enterprise and is only available on the Photon and P1 (Gen 2). It is not available on the Argon (Gen 3).

// SYNTAX
WiFiCredentials& WiFiCredentials::setIdentity(const char* identity);
// EXAMPLE - setting PEAP identity (username)
WiFiCredentials credentials("My Enterprise AP", WPA2_ENTERPRISE);
credentials.setEapType(WLAN_EAP_TYPE_PEAP);
credentials.setIdentity("username");
Parameters:
identity: inner identity (string)
setOuterIdentity()
WiFiCredentials::setOuterIdentify, setOuterIdentify, WiFiCredentials.setOuterIdentify
Sets EAP outer identity. Defaults to "anonymous".
// SYNTAX
WiFiCredentials& WiFiCredentials::setOuterIdentity(const char* identity);
// EXAMPLE - setting outer identity
WiFiCredentials credentials("My Enterprise AP", WPA2_ENTERPRISE);
credentials.setOuterIdentity("notanonymous");
Parameters:
identity: outer identity (string)
This is a feature of WPA Enterprise and is only available on the Photon and P1 (Gen 2). It is not available on the Argon (Gen 3).
