DWM1001 tag unable to communicate with anchors

Hi,
I am currently working with DWM1001C anchors and tags. All the nodes are communicating in the same network and it works pretty well so far.
However, when a tag is out of the network for a certain amount of time, this tag cannot communicate anymore with the anchors and I don’t know why. I searched for hours but did not find anything interesting. The consequence is that when I try to connect via UART with PuTTY, nothing happens. The only thing I found to solve this issue is to reboot the tag, and then it works again.

Does someone have any idea ? It would be greatly appreciated !

Try to enable responsive mode. If you use low power mode, it sleeps a lot to conserve power.

If i’m not mistaken, disabling responsive mode will make the tag have this behaviour: after tag lost the anchor, it tries to look for anchor every 10 second. If the tag still has not found anchor, after a while it will look for anchor every 60 seconds.

Hi,
The tags are already in responsive mode and not in low power mode.

Hi @Maximus
this is strange. How long is the “certain time”?

I would say more or less 30 min.

I have also experienced this problem. I managed to implement a workaround in the user code that just resets every tag once per 5 minutes, but it would be better if there was a more elegant solution. I experimented with trying to see if the UWBMAC or BH INITIALIZED changed events trigger, but I havent been able to reliably reproduce this behavior in shell mode which makes it difficult to troubleshoot.

Hi,

PANS 2.0 is quite an old version and there might be this issue.

Have already emailed about PANS PRO.
