What do I need to do to get a new replacement HAT?
Please proceed for a replacement with the right HAT. Please find the procedure from the refund and replacement policy .
Thanks.
I’m having some similar problems (quectel-CM) to what other users have reported on this thread and made no progress towards a solution based on thread suggestions so far. This is a new install on a Rpi4 and hat/modem hardware purchased from sixfab about a month ago. Below is the initial indications of trouble. Following that is some system info (same requested of other users to help troubleshoot). Can anyone suggest a path forward? Does the ether driver being assigned to the device have anything to do with it?

Hi @kevin.lorensen,
You need to configure the module. Please send AT+QCFG="usbnet",0 command, then reboot the module after 10 seconds AT+CFUN=1,1.
Please check again after doing that.
Thank you.
Thank you Ensar. That broke the logjam.
Hi @ensar,
I having a similar issue with the latest Raspi version installed as well:
The install script fails at
Checking Kernel

This is the info i have

What do i do to get this running?
Hi,
Please have a look at the troubleshooting guide. Could you please elaborate a bit more or point to more detailed information?
Hi @ensar,
We have the IOT shield from Sixfab.
Currently we are running IOT shield with the PPP script.
But for better reliability, we want to move to the QME Script.
To do this i first uninstalled the PPP services. But when I try to follow the instructions above to install the driver the install script fails at Checking Kernal.
We have the Raspberry Pi 3 Model B Rev 1.2, with the latest patch and stable release.
Please advise on what should be the steps to make sure we can get the QME working?
We only support PPP for Cellular IoT HAT.
I was getting this same issue as reported by some others in this post:
$ sudo ./quectel-CM -s internet
[02-03_17:32:40:405] Quectel_QConnectManager_Linux_V1.6.0.12
[02-03_17:32:40:406] network interface '' or qmidev '' is not exist
[02-03_17:32:40:406] qmidevice_detect failed
[02-03_17:32:40:406] qmidevice_detect failed
The HAT wasn’t showing up as a USB device:
$ lsusb

Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
It turns out that this was because I had a second HAT board stacked on top of the Sixfab HAT. This was using GPIO26 and so causing the Sixfab HAT to power off. The solution was to cut the SJ1 solder jumper for the HAT_PWR_OFF line, as described here:
Just thought I would post this in case it helps out anyone else who has this problem and ends up here after a google for the error message.
Hi, I noticed you mentioned that only PPP is supported for Cellular IoT HAT. Is this still the case now? I purchased the LTE-M HAT with Telit ME910C1-WW and cannot get the lease from udhcpc. Can the board using qmi? or only ppp? Thanks.
The Cellular IoT HAT mentioned here is a Quectel based HAT.
We will continue discussing the ME910 in other threads you have opened.
Hello i have the same issue when i try to install ./qmi_install.sh
