WiFi PRO 03: Get IP

This example shows how to get information once the module is connected to the AP. The following settings are read: - IP address - GW address - Netmask address - DNS 1 address - DNS 2 address

Required Materials

1 x Waspmote 1 x Battery 1 x WiFi PRO Module

Notes

- The battery has to be connected. - This example can be executed in Waspmote v15

Code
