Hi, Just wanted to pass this along... with the latest Raspbian (09/26/19) the thingy52 will consistently disconnect after about 90 seconds (+/- a few seconds). You can easily reproduce by installing any Pi (I've tried a 3 and a zero/w) with the current Raspbian Buster(09/26/19), connecting a thingy via bluetoothctl, and waiting 90 seconds. It doesn't matter if there is activity during those 90 seconds or not (characteristic reads/writes/notifications, etc.). At about 90 seconds you'll get disconnected consistently. On the one hand older Raspbian versions didn't have this issue (that I'm aware of), but on the other I've tested several other BLE sensors with the 09/26/19 build and none of them (so far) have displayed a similar issue. This isn't critical or anything (to me) but thought I would pass it on. Also note that as of today at least (12/17/19) it doesn't make any difference if I've updated the 09/26/19 build with the latest updates or not (apt-get update/upgrade). Lastly, I am running the newest firmware on my Thingy (though my thingy hardware is probably one of the earliest). If I can answer any additional questions let me know but it should be very easy to reproduce. Thanks...
