So, it had a fixed GPS location set, but with poor accuracy. It was close enough that I was able to figure out which mountain/ridge line it was on. That was my starting point.
After I got up there, I just used my own thinknode m1 handheld and the “signal quality” reporting feature in the app to repeatedly request signal quality reports from it. By holding the m1 in front of my chest, I could sort of make a directional 180deg antenna as my body would make the signal drop about 10dbm RSSI when facing away from the node vs facing towards it. After wandering in the wrong circular direction for a bit I eventually found it in the tree.
Its fun and easier than you think to do!
Without the GPS location as a starting point, you could do the same thing using the signal quality report if you had a much narrower search beam using a directional yagi or something. It would just take way longer.
That’s such a creative solution to tracking it down! Great treasure hunt
