Over the Air Programming (OTA)

23. Over the Air Programming (OTA)

23.1. Overview

The concept of Wireless Programming or commonly known as Programming Over the Air (OTA) has been used
in the past years overall for the reprogramming of mobile devices such as cell phones. However, with the new
concepts of Wireless Sensor Networks and the Internet of Things where the networks consist of hundreds or
thousands of nodes OTA is taken to a new direction.
Libelium provides an OTA method based on FTP transmissions to be used with GPRS, 3G, 4G and WiFi modules.

23.2. OTA with 4G/GPRS/WiFi modules via FTP

It is possible to update the Waspmote's program using Over The Air Programming and the following modules:
4G/3G, GPRS or WiFi module.
The Waspmote reprogramming is done using an FTP server and an FTP client (which is Waspmote itself). The FTP
server can be configured by Meshlium. Otherwise, the user will have to setup an FTP server.
