I’m following the QSG Calyx guide for setting up the Calyx with a Raspberry Pi, specifically the section about Calyx 5G Red Cap / EBD070.
Somewhere around step 2 and 3 in the guide something goes wrong. I can do the “sudo apt-get update”, then when installing the driver package everything seems to go alright. Only remarkable messages in the terminal are:
- rmmod: ERROR: Module qmi_wwan is not currently loaded
- rmmod: ERROR: Module option is not currently loaded
Which should not be any problems.
However in step 3 it says ModemManager should create /dev/ttyUSB interfaces, but no such files are made.
The Raspberry Pi does not detect that the Red Cap is connected, says there are no modems, and there are no /dev/ttyUSB-files.
We have:
- Tested the cable connecting Red Cap and Raspberry Pi, it is not faulty and works fine between phone and laptop. Also tried connecting Red Cap to laptop via same cable, Red Cap was not detected.
- Switched to a stronger power source, so power is not the problem
- Checked all LEDs on the Red Cap, they are lit up as they should (PWR, NET_IND, NET_STAT)
- Called Teltonika support
AI is suggesting it might be a defective unit or that the modem is in a bricked/stuck firmware state which requires a recovery tool.
Has anyone encountered a similar problem, and if so how was it resolved? I would appreciate any help and thoughts regarding what might be wrong and what I could do to fix it, thanks!
