Re: how to change uwb update rate
In TWR mode there is no hard limit, you can just scann more anchor in the tag. For TDoA mode there is a harder limit of 8 anchors: the anchors are time-slotted using TDMA, so there needs to be a modification on the TDoA anchor to add more timeslot in TDMA. The tag mode is a TWR tag mode. For TDoA y...

Re: how to change uwb update rate
For TWR, one reason could be that you modified the algorithm in such a way that you are starting a new ranging before the previous is finished, this would induce this kind of problems. You can test this assumption by putting back the 10ms timeout and see if it solves the problem. If it does, you sh...

Re: how to change uwb update rate
Do you mean that by changing the printf you get different precision? Are you sure you are printing the anchor ID correctly? For TDoA mode, you can put the node in sniffer mode and switch the sniffer to binary (there is a python script for that). This will give you all the raw packets and they can b...
