I have been trying to connect the Quectel EG25GGB-256-SGNS chip to AGL with little success.
I am running Jellyfish 10.0.1 on a 2GB, RaspberryPi4 board. The chip is mini PCI connected to the RPi4 via usb.
This is my dmesg output:

So I've corrected that "No support over 100mA line by adding the following rule to /etc/udev/rules.d/99-usb.rule:
ACTION="" SUBSYSTEM=="usb", DRIVER=="usb", KERNEL=="1-1.2.3", RUN+="/bin/sh -c 'echo 1 > /sys/bus/usb/devices/1-1.2.3/bConfigurationValue'"
However, the modem is not connecting to LTE. Here is my output for connmanctl services:
Bell cellular_xxxxxxxxxxxxxxxx_context3
Bell cellular_xxxxxxxxxxxxxxxx_context2
Bell cellular_xxxxxxxxxxxxxxxx_context1
And for context 1:
It's the same for the other contexts.
My journalctl looks like this when I try to run "connmanctl connect cellular_xxxxxxxxxxxxxxx_context1":
And for context 1:

Also, the gps does not connect, giving the error "No GNSS 3D fix".

Do I need to configure the modem in ofono? Any help would be appreciated. I need to make this work!
