Thanks for your response. Actually, I want to implement the UWB network in which
we have the following scenario:
1.Configure Anchor Initiator including position coordinates
2.Configure additional anchors
3.Configure 1 tag
All devices should be in the same PAN(uwb network)
4.Configure one DWM1001-DEV Node as a Bridge node.
5.Configure the PAN ID of the Bridge node at /etc/dwm1001/dwm1001.config
6.connect an MQTT client to the Pi and subscribe to $SYS/# and dwm/# to know about tag location.

Can you suggest me how to proceed in a programming way??

Hey Patrick, this is all looking good but when it comes to running the code I get the following error:

Traceback (most recent call last):
File "/home/raspberry/Documents/projects/dwmTest.py", line 21, in
if ("DIST" in data and "AN0" in data and "AN1" in data and "AN2" in data):
TypeError: a bytes-like object is required, not 'str'

Any thoughts on solutions?
