I can not see position tag in listener mode

Hello,
I have 4 DWM1001-DEV
an anchor, an anchor initiator, an anchor listener, and a tag.
When I send the command “les” in the anchor listener, I don’t get the position of the tag, I only get this:

dwm> les
dwm> [004312.480 INF] loc_data: 1
0) D72E[nan,nan,nan,0,x05]

[004312.580 INF] loc_data: 1
0) D72E[nan,nan,nan,0,x05]

[004312.680 INF] loc_data: 1
0) D72E[nan,nan,nan,0,x05]

[004312.780 INF] loc_data: 1
0) D72E[nan,nan,nan,0,x05]

[004312.880 INF] loc_data: 1
0) D72E[nan,nan,nan,0,x05]

[004312.980 INF] loc_data: 1
0) D72E[nan,nan,nan,0,x05]

How can i have the position of the tag.
Awaiting any replay, best regards

Hi Luis,

To get a position you need at list 3 actives anchors. Note that the anchor listener does not behave as an active anchor.

So you nee to setup the following:
-3 anchors (at least 1 initiator)
-1 tag
-1 listener (not mandatory)

Hope it helps,
Yves

I have tried with 3 anchors + 1 tag + 1 listener, but I still cannot read the tag’s position from the listener. I could read it from the tag itself, though. I tried with both les and lec commands.

ok, now is working, i put 3 anchor+1listener+1tag and work perfectly, only if you put the 3 anchors in the same line, i mean x=0,Y=0,z=0 , x=5, y=0,z=0 and x=8 y=0 , z=0 do not work, must form a triangle.
Thank you for your answer.
Best regards

Thanks for sharing that. It is working for me now.

I have 4 anchors, 2 tags and 1 listener connected through usb to my mac.
But on les or lec it gives nothing.
I can see tags position in app grid but nothing through listener.
here is what my listener looks like:

dwm> si                                                                      
[011398.030 INF] sys: fw2 fw_ver=x01030001 cfg_ver=x00010700
[011398.030 INF] uwb0: panid=x09D9 addr=xDECAAF608B240189
[011398.040 INF] mode: bn (act,-)
[011398.040 INF] uwbmac: connected
[011398.040 INF] enc: off```

I dont understand why it doesnt show any position or anything on typing `les` or `lec`
