Yes, I read the document a little while struggling with this step Install below MBPL R20 USB driver for qmi_wwan and qcserial by “make” and “make install”
Then have you installed the driver?
Trying using SDK oem@lamhas-pro:~/Downloads/MBPL_SDK_R35_ENG4-lite.bin/SampleApps/lite-qmi-connectionnnection-managerhostx86_64
lite-qmi-connection-manager v1.0.2308.1
Open transport “/dev/cdc-wdm5” on USB device in QMI mode
Interface id: 0x8
InitializeRegularService eWDA failed.EnableQmap failed.
InitializeRegularService eDMS failed.
you need to get a linux engineer to work on driver and SDK
I tried SDK it is not connecting the modems and compiling giving an error

If you help to understand the error
Are you able to compile the usb driver?
If you see the document, you can use at!scact command to establish data connection
Yes , actually [MBPL_DRIVERS_R35_ENG4-bin.tar](javascript:void(0)
[gz] 644KB does not have the make file so I downloaded the [MBPL_DRIVERS_R35_ENG4-usb-src.tar](javascript:void(0) [gz] 25KB that does have the make file and able compile and install the driver now working on 6. Use minicom to type AT command through /dev/ttyUSB2
AT!GSTATUS? should return network registered
If you see the document, you can use at!scact command to establish data connection
Please advise, I am getting an error.
oem@lamhas-pro:~/Downloads/USB/usb$ at+cgdcont
at+cgdcont: command not found
oem@lamhas-pro:~/Downloads/USB/usb$ at!scact=1
-bash: !scact=1: event not found
oem@lamhas-pro:~/Downloads/USB/usb$ sudo at!scact
-bash: !scact: event not found
oem@lamhas-pro:~/Downloads/USB/usb$
You need to use minicom to enter AT command
$ minicom
Here seems you can create the wwan interface:
does the qmi_wwan loaded?
Have you set up correctly for the APN in AT+CGDCONT?
what is the return of AT!GSTATUS?
Is it the same for MC7430?
BTW, you should enter AT!SCACT=1,1
total 3 modems installed in the computer MC7304 & MC7430 modems

you need to add question mark in AT!GSTATUS?
What is the problem now?
wwan0 is not created?
why you have some many cdc-wdm interface?
Can you just connect one module to avoid confusion?
Can you post the kernel log once you connect the module to the host?
