Can use AT commands but no uqmi

I am again having different trouble about my 4G modem on the GL-Ix750 Router

I can do this:
picocom -b 115200 -r -l /dev/ttyUSB3

AT+CPIN?
+CPIN: READY

OK
AT+CGREG?
+CGREG: 0,1

OK
AT+COPS?
+COPS: 0,0,"vodafone GR",2

OK
AT+QSPN
+QSPN: "vodafone GR","voda GR","",0,"20205"

OK
AT+CGDCONT?
+CGDCONT: 1,"IPV4V6","","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0
+CGDCONT: 2,"IPV4V6","ims","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0
+CGDCONT: 3,"IPV4V6","sos","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,1

OK
AT+CGACT?
+CGACT: 1,0
+CGACT: 2,0
+CGACT: 3,0

OK

and use AT commands just fine, but it's not possible to do any kind of qmi command.
So there is no response to any of those:

uqmi -d /dev/cdc-wdm0 --network-scan
uqmi -d /dev/cdc-wdm0 --get-data-status
uqmi -d /dev/cdc-wdm0 --get-current-settings
uqmi -d /dev/cdc-wdm0 --get-serving-system	
uqmi -d /dev/cdc-wdm0 --get-signal-info

here the dmesg:

I suppose you have the packages installed?

opkg list-installed | grep qmi

yes they are installed


root@OpenWrt:~# opkg list-installed | grep qmi
kmod-usb-net-qmi-wwan - 5.4.188-1
libqmi - 1.28.8-1
luci-proto-qmi - git-22.046.84868-a7b0fe1
qmi-utils - 1.28.8-1
uqmi - 2020-11-22-0a19b5b7-3

Perhaps you can pop back into your other thread. The members were following your qmi issues closely. Hope all end well :crossed_fingers:

I did a total re-install of the system so I would consider it a new problem
