dan_ackme 1:44eae7ea80c7 3 *
dan_ackme 1:44eae7ea80c7 4 * This is an example of using the web setup network API to
dan_ackme 1:44eae7ea80c7 5 * configure the module network credentials remotely.
dan_ackme 1:44eae7ea80c7 6 *
dan_ackme 1:44eae7ea80c7 7 * It works as follows:
dan_ackme 1:44eae7ea80c7 8 * 1. Instantiate the WiConnect Library
dan_ackme 1:44eae7ea80c7 9 * 2. Initiate Communication with WiFi Module
dan_ackme 1:44eae7ea80c7 10 * 3. Start WebSetup with specified parameters
dan_ackme 1:44eae7ea80c7 11 * 4. Wait for web setup webpage to complete
dan_ackme 1:44eae7ea80c7 12 * 5. That's it!
