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.
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.
