LTE + raspberry 3

JPT2 · August 4, 2025, 9:40am

Hi,

I would like to use an old Telekom Speedstick LTE II on my raspberry 3.

it seems to work from Archlinux on my laptop, see last code block below.

it doesn’t work on openwrt yet. any help would be appreciated.

this device id is unknown by usb modeswitch, on arch and on openwrt.

why are there 3 ttyUSB? it does not answer AT commands, which baudrate and 8n1 do i need?

This is what i achieved on arch after starting Modemmanager:

I cannot find how to start modemmanager on openwrt.

this https://openwrt.org/docs/guide-user/network/wan/wwan/modemmanager tells to use menuconfig. so i do have to compile the kernel? I hope there is a guide for crosscompiling. don’t want to build on Rpi3

what about the command line tools like mmcli and qmicli? couldn’t find them either. where to they come from?

thank you very much

ps. moving to the real computer now, fetching kernel source

pps. the editor wanted me to add tags, but I don’t see any way to add them?

Don’t use ModemManager, follow https://openwrt.org/docs/guide-user/network/wan/wwan/ltedongle

Please share the result of cat /sys/kernel/debug/usb/devices

Mh. Just now I neither have /dev/ttyUSB* nor any block device. maybe missing some kernel modules?

that’s what the link @AndrewZ shared with you is all about ?

JPT2 · August 4, 2025, 10:38am

Ah, I was following the guide from start, which led me to other links before I saw the section about packages. wrong order?

Now I got it.

The guide was missing: reboot after installing the packages. then go to luci web interface.

APN is sipgate, no IPv6.

but which authentication do I use?

well, seems to work with sipgate/sipgate.

thank you very much.
