Hi! I realy need your help. After my not quite competent conversion from full MBIM to QMI (but wrong mode), AT!USBCOMP? AT!USBCOMP=1,3,0101 AT!RESET I have no way to change the modem composition and activate the AT port. I have tried windows driver with changed parameters, [Default Values] SILENT=0 SS=1 MBBDRIVER=1 LOCATIONDRIVER=1 WIN8LOCATION=1 LOG=1 BUSDRIVER=1 WIN8BUSDRIVER=1 USBCOMP=8 CHECKFORDEVICE=0 GPS=1 GPSAUTO=1 GPSRADIO=1 DisableUsbCompAutoUpdate=1 With no luck. This also root@ImmortalWrt:~# qmicli -d /dev/cdc-wdm0 --dms-get-operating-mode [/dev/cdc-wdm0] Operating mode retrieved: Mode: 'online' HW restricted: 'no' root@ImmortalWrt:~# qmicli -d /dev/cdc-wdm0 --dms-swi-set-usb-composition=8 error: couldn't set USB composite modes: QMI protocol error (94): 'NotSupported' Also I have reflashed firmware.

Can you do AT command with the only port enumerated? how about changing the USBCOMP to 9 in configuration.ini?

I have tried now. No luck. Just DM port. [image]

[image] jyijyi: mmand with the only port enumera ttyUSB0 not reacting for AT-commands.

probably you need to contact Sierra FAE to get a tool to configure it

How to reach this guys (Sierra FAE)? Maybe there are another approach to fix it?

how about changing the USBCOMP to 9 in configuration.ini and reinstall the windows driver?

You need to contact distributor to get a tool called setusbcomp.exe for em7565 module

Is the any advices how to do it, due to I have bought it in on aliexpress?

can you return the goods there as it is not fully functioning?
