I have a Hologram Nova U201 and am using it with a Raspberry Pi to get a cell connection. I recently rebuilt the Pi’s image with up to date software because Raspbian 10 is now available. However, I can’t seem to get the Hologram modem to work anymore. It successfully creates the ppp0 interface and gets an IP, but I can’t ping. I am now using hologram-python 0.8.2, and was previously using 0.7.6. I wasn’t able to figure out how to install the old version on Debian 10 to test and see if that works. Is there a way?
Successful hologram network connect:
