can you suggest how I run this code on Raspberry Pi to get the position of the tag on the Raspberry Pi terminal??? It will very helpful to me!

You need to install a redis database and run it on port 6379. After connecting the tag via USB to port /dev/ttyACM0 (on my pi), you can execute the code after installing python with python dwm1001-localization.py which will store/update the x and y positions into the redis database as json string to the key "pos".

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?
