Hello,
NON EXISTING IN FORUM
I have read the forum and did not find anything like this. There is a similar topic regarding IA hedgehog problems but it was because he did not have beacons with different frequencies.
MY SETUP
I have 6 different Super Beacons, of wich 4 have different frequencies and 2 have the same and a 5.1HW modem. I have uploaded the IA firmware to all beacons and modem and reset them all.
I have created a submap and a map with its service zone with 3 fixed super beacons (all with different frequencies). I am also able to track the position of two mobile beacons which have the same frequency (25Khz). Until here everything is perfect, the positioning of each beacon moves in +- 1cm.
THE PROBLEM
The problem comes when I try to pair them. I paired them and modify the values for the distance and position between them. At this moment they both dissapear from the dashboard and I cannot see their position nor orientation. I have also tried to do this with two super beacons with different frequencies but I get the same result. I have tried to pair them via UART following the steps in the manual.
When uploading NIA firmware to all beacons and modem I can pair them with the same map and same distance between paired beacons. Somehow this does not work when working in IA mode.
Thank you,
IA Pairing loses position
Re: IA Pairing loses position
The answer consists of several parts/dimensions. Thus, you shall assess your problems and solve it from several dimensions as well.
1) Do it in small steps
Before going to any pairing:
- Achieve perfect tracking with a left hedge
- Then - with the right hedge. Absolutely independently from the left. You can even turn off the left one
- Repeat the same with both but in non-paired mode
- Make sure the distances are set right in the Dashboard, and they really match the real distance
- Make sure you are not mixing up left and right
- Make sure your map is inverted (left and right on the map is not mixed up)
- Only after that attempt to pair the beacons
2) The setup with 6 stationary beacons is not entirely clear ... Make sure there are no mistakes with frequencies:

IA is very powerful but it may be too easy to make mistakes with it.
3) Do you really need three beacons per submap?
- If you do 2D, then the optimal solution is either two or 2+2 beacons for Fully Overlapping Submaps. Three beacons mean 3D automatically. But 3 beacons for 3D is suboptimal because it would be prone to non-line of sight. Thus, we always recommend 3+1 per submap for 3D. But then, again, did you plan 3D really?
