Hi all,

we're using the Loco Positioning System with 8 anchors that placed according to the description on the website.
Since today we're expecting an issue with two of the anchors.
Both anchors are not reachable by the Crayzflie 2.1 drone (Using the Crazyflie client). The two affected anchor nodes are also showing a different LED pattern than the others that are still working (https://photos.app.goo.gl/wMZ2xszEtHMeFaig8).
The transmission led (TX) is off and is not flickering.

We updated the firmware for both nodes, since they we're not reachable. Unfortunately, I don't know if the LED behavior was there before as well....

We're are grateful for any professional assistance .

Thank you.

Tx not blinking means that the anchor is never transmitting. With the mode Led lit it seems that the node is configures in TWR mode, if this is not what you have for the other anchors you should try to re-configure these anchors using the lps config tool or by connecting directly to the anchor serial port: https://www.bitcraze.io/docs/lps-node-f ... el-config/

Thank you - that worked!
