Stay tuned for a follow-up post with dedicated nRF52 scanners and multiple MAC address broadcasting tags which will let us get more precise results on the limits of broadcasters in the area.
Any idea where to find the follow up? Did it ever take place?
I never got around to making the part 2 of the experiment, but thanks for letting us know there would be interest in it. This is something I want to try out with the new Ruuvi Gateway if I can find the time.
