    Hi,

    I want to enable internet on my Raspberry Pi, so I ordered Raspberry Pi 3G-4G/LTE Base Shield V2 and Quectel UC20-G Mini PCle 3G Module.

    I followed the instructions from https://sixfab.com/ppp-installer-for-sixfab-shield/ and edited the /etc/chatscripts/chat-connect script to add the AT+CPIN command.

    After I entered sudo pon, I get +CME ERROR: SIM not inserted^M.

    The whole chat-connect script is:

    The SIM-card is, of course, inserted.

    It would be great, if you could help me.

    Sincerely,
    David

    Hi David,

    Could you please remove the pin from the sim and try?

    Best regards

    Hi,

    thanks for the quick reply!

    I’m not able to do that.

    But it works now. After I removed the shield from the Raspberry Pi, restarted, put it on again, do sudo pon, the connection is established!

    But I got another problem. Everytime I restart the Raspberry, the interface is not comming up when the pin header and USB is connected. I need to remove everything again, restart it and then, sometimes, it works. If the shield is only connected via USB, everything works fine. Hence I think there is a problem with the pin header connection in combination with USB. Do I need to turn something off?

    Best regards

    Hey,

    Is there anything that is keeping the GPIO busy behind? Could you please check it?

    Hey,

    I just use SPI in addition to the Shield. Which GPIOs are crucial?
