WiFiNINA - WiFi.beginEnterprise()

Description

Initializes the WiFiNINA library’s network settings for a common WPA2 Enterprise network with username and password authentication (PEAP/MSCHAPv2).

Note: this feature requires NINA firmware version 1.3.0 or later. All string parameter supplied must have a combined length of under 4000 bytes.

Syntax

WiFi.beginEnterprise(ssid, username, password);
WiFi.beginEnterprise(ssid, username, password, identity);
WiFi.beginEnterprise(ssid, username, password, identity, ca);

Parameters

  • ssid: the SSID (Service Set Identifier) is the name of the WiFi network you want to connect to.
  • username: username part of WPA2 Enterprise (RADIUS) credentials
  • password: password part of WPA2 Enterprise (RADIUS) credentials
  • identity: WPA2 enterprise identity (optional)
  • ca: root certificate (string) to validate against (optional)

Returns

  • WL_CONNECTED when connected to a network
  • WL_IDLE_STATUS when not connected to a network, but powered on

Example

/*
  This example connects to a WPA2 Enterprise WiFi network.
  Then it prints the MAC address of the WiFi module,
  the IP address obtained, and other network details.
