Modem: RM500Q-GL
Driver: V1.2.0.23
OpenWRT: 21.02.3
Hello all,
I have managed to integrate the driver into OpenWRT on a Raspberry Pi 4B. To me everyhing looked fine, but in the logs I am getting an error message and indeed I do not have the /sys/class/net/wwan0/qmi/raw_ip directory. Not “qmi” dir and also not “raw_ip” dir in the wwan0 folder.
dev:
/dev/cdc-wdm0
/dev/ttyUSB0
/dev/ttyUSB1
/dev/ttyUSB2
/dev/ttyUSB3
all there.

Error message in OpenWRT:
daemon.notice netifd: modem (7884): Device only supports raw-ip mode but is missing this required driver attribute: /sys/class/net/wwan0/qmi/raw_ip
First use of uqmi e. g. with uqmi -d /dev/cdc-wdm0 --get-data-status I do get a response. All further use I do net get a response anymore.
With AT-commands I can see, that modem is registered, connected and has IP address.
Any ideas?
Best regards
Mike
