Hi,
I’m currently facing this issue with the 3G-4G/LTE base shield. I downloaded and ran the ppp installer script from Sixfab github repository. I want to establish a PPP connection and to run it I issue the $ sudo pon command, here is the output:
pppd options in effect:

The same happens if I try to create the connection with sudo pppd call gprs

Script chat -s -v -f /etc/chatscripts/quectel-chat-connect -T wap.tim.it finished (pid 16489), status = 0x3
Connect script failed
The device is correctly detected as ttyUSB3.
To be sure that the module is working I also used minicom to communicate manually via AT commands on ttyUSB3, and in this case I was able to get the correct answers (all commands listed in the /etc/chatscripts/chat-connect receive the expected answer)
Moreover, I tried the module on another raspberry and another PC, both of which run succesfully the pon command.
Could you help me understanding why am I getting stuck with the AT commands?
Thank you very much,
Best Regards,
Sandro
