Issue #59: the short article about Blue Dot ... many thanks for making me aware of it, this was right on time!
For some time I was in need of a simple remote control to a set of demonstration Pi Zero Ws and 3Bs, which I need to cleanly shut down after a demo. So far, I had to ssh into them. While Python has very good Bluetooth support, I was lost; and then I would need to come up with a small Android app too.
Thanks to the Blue Dot I could quickly integrate it into my demo Pis. Beside a looong press of the blue dot for shutdown, I also added some other remote control functionality that works by tapping the dot, or by press-n-hold, and then swiping.
So, this volume of the MagPi is my favorite one!
