In the previous chapter, we built and deployed a server application to broadcast data coming from one or more sensors to the outside world via a classic Bluetooth connection. We tested the application by connecting to it by means of the standard Qt Bluetooth Chat example.

We will also show how to provide multi-language support to our users with ...
