Embedded Programming with Modern C++ Cookbook

Deploying software remotely

The deployment of software for embedded systems is often a complex procedure that should be carefully designed, implemented, and tested. There are two major challenges:

• Embedded systems are often deployed in places that are difficult or impractical for a human operator to access.
• If software deployment fails, the system can become inoperable. It will require the intervention of a skilled technician and additional tools for recovery. This is expensive and often impossible.

A solution for the first challenge of embedded systems that are connected to the internet was found in the form of Over-the-Air (OTA) updates. A system periodically connects to the dedicated server and checks for available updates. If the updated ...
