I’m trying to make the Digi Shield work on a raspberry 3. I have tryed to connect the the shield equiped with Xbee PRO S2C Zigbee antenna with both GPIO and USB but I’m not able to read recived data. The strange thing is that if I connect to a desktop pc the Shield with USB everthing work. I have tried with digi-xbee python libary (https://xbplib.readthedocs.io/en/latest/) and with xbee-python library (https://python-xbee.readthedocs.io/en/latest/). On my desktop works fine on the RPi3 is not working.
