Hi,
I just installed the BerryGPS+GSM on a Raspberry pi 0, followed all instructions for hologram, but it does not work. The main failure is with setting the APN. I did a screen on /dev/ttyACM0 and issued some test commands, as suggested by hologram forums. See the log below. I get stuck with the error response on at+cgdcont, that is the main thing that fails, see the last few lines in the log below.
Running from a 2A power source and added the max_usb_current=1 configuration.
Any suggestions welcome.
Thanks,
Mihai

Can you show me the output of the below commands.
First, enable extended error commands with
AT+CMEE=2
The enable unsolicited messages
AT+UGIND=1
Check the SIM status
AT+cpin?configure APN
AT+UPSD=0,1,”hologram”Are you registered?
at+cgreg?
What is you profile status?
AT+UPSND=0,8

If possible can you please send it to sales @ ozzmaker.com.
You may have a faulty unit which may need replacing.
