Tag label does not change in silent anchor data

My network consists of 6 active anchors, 2 tags and 2 passive anchors. I noticed that the labels/names of one of the tags matched with an anchor so I tried changing the label of the tag from the DRTLS app. The data received on the silent anchors from the ‘lec’ command had the older tag label.

I tried changing the label using the ‘nls’ shell command and I verified that the label had changed on the tag by sending the ‘si’ command. I also tried these commands on a different tag. But the data from the passive anchors always showed the old label.

Data from the passive anchor:
POS,0,89A0,nan,nan,nan,0,x06
POS,1,D494,nan,nan,nan,0,x0C
POS,0,89A0,0.57,0.42,0.13,80,x06
POS,1,D494,0.51,0.95,0.19,72,x0C
POS,0,89A0,0.56,0.44,0.10,99,x06
POS,1,D494,nan,nan,nan,0,x0C

‘si’ command output from the tag:
[000011.010 INF] sys: fw2 fw_ver=x01030001 cfg_ver=x00010700
[000011.010 INF] uwb0: panid=xB40C addr=xDECA3D167801D494
[000011.020 INF] mode: tn (act,twr,np,le)
[000011.020 INF] uwbmac: connected
[000011.020 INF] uwbmac: bh disconnected
[000011.030 INF] cfg: sync=0 fwup=0 ble=1 leds=1 le=1 lp=0 stat_det=1 (sens=1) m
ode=0 upd_rate_norm=1 upd_rate_stat=1 label=beacon1
[000011.040 INF] enc: off
[000011.050 INF] ble: addr=DE:AB:C6:A9:41:3F

The ‘si’ command output shows that the label has been set to ‘beacon1’ but the data from the passive anchor shows the label as ‘D494’.

How can I change the tag label displayed in the passive anchor’s data?

Hi @tsg97
you cannot change the label displayed in the passive anchor.

The nls command only change the node name via BLE interface, but it does not change its address.

Hi @leapslabs,

Thanks for your reply!
In scenarios where a large number of tags are present and it’s used with passive anchors, there is a high probability of 2 tags having the same label. Can you suggest some method by which we can differentiate between the tags?

Thanks

Hi @tsg97
unfortunately there is no solution for this in PANS firmware. PANS firmware is supposed to be used for technology demonstration.

Anyway I have seen a installations with hundreds of tags without address collision. But yes, there is a small chance that address collision will occur - then I would propose to sell that tag to another customer.
