WiFi Ping

This example connects to a encrypted WiFi network (WPA/WPA2) then it prints the MAC address of the WiFi module, the IP address obtained, and other network details. After this initial phase, the loop continuously pings a given host, specified by IP Address or name.

Hardware Required

Circuit

The WiFi module is integrated on your board and you don't need any special circuitry to get this tutorial to work.

Arduino MKR WiFi 1010
Arduino MKR VIDOR 4000
Arduino UNO WiFi Rev.2


Please note: these three boards use dedicated pins to communicate and select the WiFi module, therefore you have no restriction in the usage of the available digital pins connected to the header pins.

Code

You should have access to a 802.11b/g wireless network that connects to the internet for this example. You will need to change the network settings in the sketch to correspond to your particular networks SSID.

For networks using WPA/WPA2 Personal encryption, you need the SSID and password. The module will not connect to networks using WPA2 Enterprise encryption.
