you can use option “8. Modify an existing profile on the device” to modify the APN.
does it work with mbim-network command?
you need to install:
sudo apt-get install libqmi-utils
sudo apt-get install libmbim-utils
I will first try with mbim-network command
Do I need to install the FW also for the EM9191 I received from the package ?
you can use the FW here:

When I used mbim-network command, I see the connection started.

But when I tried with lite-qmi-connection-managerhostx86_64 I got the below error.
Transport_Initialize failed. Do i have to use the latest FW for working with connectionmanager? The current FW is below:
AT!IMPREF?
!IMPREF:
preferred fw version: 03.06.01.00
preferred carrier name: GENERIC
preferred config name: GENERIC_030.015_000
preferred subpri index: 000
current fw version: 03.06.01.00
current carrier name: GENERIC
current config name: GENERIC_030.015_000
current subpri index: 000
OK
why don’t you just use MBIM command?
have you installed these?
sudo apt-get install libqmi-utils
sudo apt-get install libmbim-utils
Yes with mbim-network all seems to be good . I see the connection and able to ping 8.8.8.8. See my logs send earlier.
My question is to work with connection mgr , do I need the latest firmware on the modem ?
you can try the latest FW
have you installed these?
sudo apt-get install libqmi-utils
sudo apt-get install libmbim-utils
Yes I installed those packages .
Is there a tool to upgrade the firmware ? Can I know the steps .
It is exe file to upgrade firmware
Sorry I see from this link https://source.sierrawireless.com/resources/airprime/software/em919x/em9-approved-fw-packages/#sthash.qSjBa663.tu3mGnnA.dpbs
I am not sure how to run it . There is no executable I see
you can see the release note:
https://source.sierrawireless.com/resources/airprime/software/em919x/em919x-crn-release-note/#sthash.9B97PsAa.dpbs
there is a section about fw upgrade
with cinnection manager still failed with latest firmware. attached is the failure log.
AT!IMPREF?
!IMPREF:
preferred fw version: 03.10.11.00
preferred carrier name: GENERIC
preferred config name: GENERIC_030.066_000
preferred subpri index: 000

With lit-qmi-connection-managerhostx86_64 it still failing after updated the firmware with latest. Do i need to set any configuration file to pass to the binary?
attached is the failure snap
shot.
it says “Transport_Initialize failed”
I am able to make a connection with lite-qmi-connectionmgr . but it says Failed to get runtime settings. I have provided the correct APN and profile. attached is the snapshot
seems to be SIM/network issue
Why are you using GENERIC PRI for AT&T network?
What are the return of the followings?
ati3
at!impref?
AT!GSTATUS?
at+cgdcont?
at+cgpaddr=1
at+cgcontrdp
Can you try other SIM card other operator?
It is worked with mbim-network command . Issue is only with connection mgr binary
Will generic PRI will not work with AT & T?
Everything worked fine with mbim-network command .
Yes APN is broadband
of course you need to use AT&T configuration for AT&T network
What are the return of the followings?
ati3
at!impref?
AT!GSTATUS?
at+cgdcont?
at+cgpaddr=1
at+cgcontrdp
How did it worked with mbim-network command ?
No idea, but still cannot explain why it works on my side for both methods
I see it is connected in my case too . Only error I see is failed run some settings . I will check if it got an ip address. Any specific package is required to install for dhcp and dns to work automatically with lite-qmi-connectionmgr?
