Hello,
I am finally testing plotting of beacons after a false start a year or so ago after buying 10 TrackR's which turned out to be a pointless waste of money all round, both for this and for its own app (battery terrible or all just stop working after a day or 2, yay).
I have some cheap iTag ones now for £2 each. Work great . Battery lasts 6 months (had them a year now but never done anything with them) and they broadcast constantly and reliably.
The one thing is their TXPower is 0dbm so very loud. Maybe part of my issue.
I have 10 Pis' mainly Pi Zero W's, 1 original B and 2 Pi 3s. All working fine in a grid reasonably equally spaced.
What i am finding is, my X and Y positions are all over the place, one second it looks good say X =21 Y = 15... then the next second X = -3456 Y = 70 which is of course not plot-able on my image.
So, is my wild locations down to:
a) TX Power of these cheap iTags too high causing interference with the others
b) Should i be setting the TXPower of the RPis themself (they state TXPowerRecieved = -59 but is that used when TXPowerSet = 999 is set?)
b1) Does changing the TX Power settings of a Pi alter the calculation of the beacons? Is this used at all in that?
c) Should i be playing with TXPower on the beacons in the pibeacon devices? I seem to have it a bit better by setting TXPower to -50 on the beacon devices but still wild
d) Any ideas how to stabilise location?
