    Hi,

    I’m trying to get my RPI (Raspbian strecht) to work with my 3G-4G/LTE Base Shield V2 with EC25 module.
    So I installed a fresh Debian strecht to my RP3 and I followed every steps described in your tutorials :

    Solder the 2×20 pin header to shield.
    Plug module on Raspberry Pi
    Connect module via usb to Raspberry Pi or Select “On” on Uart Switch. If you connect via Uart , internet speed very slow because of uart speed.
    Use this tutorial :
    Raspberry Pi Kernel update for Sixfab 3G/LTE shield’s usb drivers

    Then I followed the https://sixfab.com/qmi-interface-with-3g-4g-lte-base-shield-v2/ because what I intended to do is just connect to internet.

    But I dont get any connection… All I have is an endless loop saying :
    “requestRegistrationState2 MCC: 0, MNC: 0, PS: Detached, DataCap: UNKNOW”
    When I launch the instruction “sudo ./quectel-CM -s mmsbouygtel.com” (as mmsbouygtel.com is my APN)

    Is there a configuration issue ?
    Am I doing smthing wrong ?

    How to debug ?
    I must say that your docs are more than very light… I do not even know where I have to plug my antennas !
    Please help.

    Usefull informations :
    ifconfig output :

    Did you run

    sudo apt-get update

    Before installation?

    You will need to connect at least one LTE antenna to Main port of the EC25 module. (IMAGE MENTIONING ANTENNA PORT)

    Hi Saeed,

    Thank you for your answer. It was an antenna issue.

    My antenna was plugged into the wrong port.

    So now I have an internet connection but when I call the ./quectel-CM script the output ends with those two lines :
    Too few arguments.
    Too few arguments.

    Do you know what it means ?

    Thanks !
