hello, I am using your library to set up 4 anchors with 1 tag for 3D position detection.
The situation of the problem is I set the distance between anchor 1-4 and tag is 1m, and test each anchor to tag is 1m, when I turn on the anchor 1, the distance of anchor 1 to tag is 1m,
turn on anchor 2, the the distance of anchor 1 to tag become 0.9m, anchor 2 to tag is 0.88m,
turn on anchor 3, the the distance of anchor 1 to tag become 0.8m, anchor 2 to tag is 0.6m, anchor 3 to tag is 0.8m,
turn on anchor 4, the the distance of anchor 1 to tag become 0.8m, anchor 2 to tag is 0.4m, anchor 3 to tag is 0.8m, anchor 4 to tag is 0.2m,
for your example [ESP32_UWB_tag2D_4A], is that the anchors do not interact with each other?
if yes, How do your solve this problem? thank you.
I have calibrate the antenna delay for each anchor to tag (just turn on a tag and an anchor to calibrate for 1m distance), but not set the antenna delay for the tag to be zero (I am not see that setting in the example of tag),
when turn on all anchors in the same time, the distance of each anchor to tag is change.
i have try to calibrate the antenna delay for each anchor to tag when turn on all anchors in the same time, it seems can fix the problem, but I need to turn on anchor 1-4 in order(1-2-3-4), if the order change ( just like 2-3-4-1), the distance will be change,
can you give me some suggestion for that? thank you.
I have try Pizzolato Davide(pizzo00)'s library, he's example cannot work like that picture,
I am using your library for the problem described in the first post.
When all anchors are turned on at the same time, I try to calibrate the antenna delay of each anchor. The problem seems to be solved, but the anchors need to be opened in sequence (1-2-3-4). and when change the antenna delay of anchor 2, ths distance of anchor 3 and 4 will be effect.
for the library of pizzo00, I see your comunication on the issue " Problem when connecting more than 4 anchors and 1 tag "
I tried using his library with his anchor and tag example but it didn't detect the distance between label and anchor.
In summary, each anchor was individually calibrated to the tag, at a fixed distance of about 7 m, as described on the Github site. The calibration was demonstrated (plot below) to be effective over a range of 1 to 8 m, giving the expected rms error of about +/- 10 cm.
