hello, so i am pretty much lost… i have been working on trying to get this to work for a couple days. i was able to get the sixfab core sim to work, but i am using a mint mobile sim card (which is based on the tmobile network iirc). i contacted mint to get the apn information (wholesale). but i have not been able to get any of the methods to work (ppp, qmi, or libqmi).
i am using a rpi 4b 8gb, via the usb connection. i tripled checked all of the antennas. i have tried all of the methods listed below with fresh installs of raspbian lite.
alright, im going to start with libqmi/qmicli
so everything seemed to be going fine up until the
sudo qmicli -d /dev/cdc-wdm0 --wda-get-data-format
this command returned the error:
error: couldn't create client for the 'wda' service: QMI protocol error (3): 'Internal'
i tried googling that but i couldnt find anything. so i tried moving on to creating the network thing with
sudo qmicli -p -d /dev/cdc-wdm0 --device-open-net='net-raw-ip|net-no-qos-header' --wds-start-network="apn='wholesale'" --client-no-release-cid
that command only worked with ip-type=6 or not specifying the type at all. if i did specify type 4, i would get a protocol error 79, policy mismatch. but i was able to start it with the command listed above, but then i tried to config the ip and default route with
sudo udhcpc -q -f -i wwan0
but that command just kept saying “sending discover” with no dhcp lease being obtained. so that method didnt work.
next, lets try the qmi quectel specific one.
when i get to the part where it tries to connect to the internet (via quectel-CM script) it gives me this:

i have also tried without the -4 and -6 options but its the same. apparently the 231 error means ip version mismatch, but i have tried it with multiple different options and get the same thing. the only thing that is different is in -6 without ipv4, and that gives me

im unsure what to make of all of this, but it seems like one of these two options would be best for my deployment case in contrast to ppp, which doesnt seem like it would work as well. either way, any kind of cellular connection via my sim card is a good start. please let me know what AT commands i should run for troubleshooting to help you all diagnose this issue the best. thanks
edit: heres a bunch of at commands and other diagnostic stuff i saw other people request in other posts
