I have OpenWrt running on Raspberry Pi with an LTE hat. I got the set successfully working as an LTE router, but I have one problem. I cannot find the modem device for giving AT commands to change the modem (SIM7600) configuration.
The modem is connected using RNDIS, and as said it works OK, but no device like ttyUSB-something is found with ls /dev/*.
So what could be the device to be used in minicom settings?
