Rpi / Base Hat / EC25-A - Attach issue

Raspberry Pi Network HATs 3G/4G&LTE Base HAT
1

Hello!

I too am having the detached issue that I’ve seen other people post about on occasion. A few notes:

HW
Raspberry Pi 4
Twilio sim card (activated via website)
Sixfab Base Hat w/ EC25-A module

Additional notes:

  1. The first time I ran step 11, I had the module attached. I shutdown the device, removed the module and re-ran it with the module disconnected. Not sure if this could cause issues
  2. Step 13 says to use the following line of code:
    cd /files/quectel-CM
    When I ran this, it didn’t find the directory and I had to change the code to:
    cd /home/pi/files/quectel-CM
    Is there a script that could be pointing to the wrong directory that is causing it to not attach properly? Is this different location a result of the Rpi4 skipping steps 4-8?

Below is the long you’ve been requesting in other posts. Hopefully the information above can help myself (and others) resolve this issue. I have a feeling based on what I commented above, this is likely related to RPi 4 (though people haven’t been posting their hardware setups so it’s probably hard to tell).

Thanks Saeed!

Here’s that log:
