Recently on the XYO network I have had the problem of my sentinel X turning itself off. Now when I got it in the instructions it is said it never turns off, that's not entirely accurate anymore.
Now some of you my even be asking what's XYO. Well it's a network built on geo mining the 1st of it's kind I know of, there are new networks forming on the principle but I've been following XYO for about 6 months to a year now and they seem legit. The sentinel X now turns itself off about every 5 minutes unless you click on the sentinel icon on the GUI on your phone and request nearby device remains on, that's a new feature and I think one they added to possibly save battery power on the sentinel. However I have found no articles until MINE that explain WHY.
So if you have XYO (coin network app) make sure you have Bluetooth enabled connect your device and then ask it stay on or you'll be resetting it every 5 minutes or so to work with your phone. I lost a lot of potential coin this way because I couldn't get an explanation and I auto-mine when sleeping but my sentinel would turn off, I even bought batteries before i noticed this. It may take several tries to get the phone and sentinel to connect correctly and stay paired but when they do its marvelous.
