EM7565 stuck in QMI mode but only with one DIAG port

IoT Modules MC/EM Series
1

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. Also no luck/changes.
Here additional hw info. I’d appreciate the help.
Thanks,
Aleksei

Can you do AT command with the only port enumerated?
Can you see /dev/ttyUSBx port in linux?

not sure if it works if you change the USBCOMP to 9 in configuration.ini
You can double check:

Continuing the discussion from EM7565 stuck in QMI mode but only with one DIAG port:

Hi!

I already tried to modify configuration.ini and ran with following way:

GenericDriverSetup_5087.exe USBCOMP=8 DisableUsbCompAutoUpdate=1
GenericDriverSetup_5087.exe USBCOMP=6 DisableUsbCompAutoUpdate=1

In Linux and ImmortalWRT I can see only ttyUSB0 unfortunately.

Can you do AT command with the only port enumerated?

how about changing the USBCOMP to 9 in configuration.ini?

6

I have tried now. No luck. Just DM port.

ttyUSB0 not reacting for AT-commands.

8

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

9

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

10

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

12

I have tried with no luck

13

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

14

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

15

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

16

I don’t think so, due to it’s result of my activities. Better to fix it, if it’s possible.

17

How about using qmicli to do factory reset?
