Hi Sunny,
When you have multiple tags in an indoor space, it wouldn’t make sense to attach each and every tag to PC and collect location data from each of it.
If you have a setup where you just want to check whether the location is being actually determined or not, you can connect the tag through USB port to PC and use serial monitor to see the data.
sudo pico com -b 115200 /dev/serial0 should do the trick, considering you are connected via serial0 port. You can check which port is being used when you connect your tag to the PC ( there are commands to see if in Windows/Mac/Linux ).
Now to address the larger question, if you have the whole setup done in larger space, then you would either need a listener or a gateway which will in-turn collect data (aggregate?) data for you by reading data from all the tags and then you can attach them to any microcontroller which will then transfer all those data to the server/local machine.
If you are using gateway approach then it’s required to use Raspberry pi 3B as of now. In case of listener any microcontroller can be used.
Hope it helps.
Thanks
