How to collect and publish data using Bluetooth Low Energy with Arduino

In this post, I illustrate operation of an Arduino with BLE (Bluetooth Low Energy). As usual, physics being my field, I do not discuss a generic example (the equivalent of “Hello, World!”), but a concrete physics application. Sometimes, for brevity or clarity, I will not be rigorous, and purists may turn up their noses, but, as I read on a A. Zee’s books, “”.
