WiFi PRO 21: OTA | Libelium

This example shows how perform OTA programming using the WiFi module. It is necessary to specify the correct AP settings. Besides, it is necessary to setup an FTP server and change the parameters defined in the example.

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
