<br>
The fact that you're running a command with --device-open-sync may end<br>
up disconnecting the device, because that cleans up all allocated QMI<br>
clients. Don't do that, don't run with --device-open-sync.<br>
<br>
Also, you need to run --wds-get-packet-statistics on the specific WDS<br>
client that got the modem connected i.e. When you run WDS Start<br>
Network on a WDS client, that client is the one that keeps the<br>
connection up, and that client is the one that will give you the<br>
packet statistics for the specific connection that was brought up.<br>
E.g. in ModemManager we use a WDS client for IPv4 and another WDS<br>
client for IPv6, and we can get packet statistics for both separately.<br>

That issue was fixed in this commit:<br>
<a href="https://gitlab.freedesktop.org/mobile-broadband/libqmi/-/commit/69354f53f180b32c8f183a1217582e557b791220">https://gitlab.freedesktop.org/mobile-broadband/libqmi/-/commit/69354f53f180b32c8f183a1217582e557b791220</a><br>
<br>
I believe what you're seeing is due to using --device-open-sync. If<br>
you use that option, you should use it exclusively on the first<br>
command you send to the module, and only if your program is the only<br>
one using the module, otherwise you're breaking the flow for every<br>
other program as well. My suggestion is to completely ignore that<br>
option, not even sure why you started to use it :)<br>

<br>
As said before, you should run the command on the WDS client that<br>
brought up the connection with Start Network.<br>
<br>

<br>
This is because you're running your custom compiled qmicli but using<br>
an older libqmi-glib library. If I had to bet, you built libqmi<br>
yourself without using a custom --prefix in configure, and so you<br>
installed qmicli in /usr/local/bin and libqmi-glib in /usr/local/lib,<br>
but when you run "qmicli" the PATH looks first in /usr/local so you're<br>
running qmicli from your newly built instance but linking to<br>
libqmi-glib in /usr/lib (probably the system-installed one). I<br>
believe it's Debian/Ubuntu the ones that have /usr/local/bin in the<br>
PATH by default and that creates a big mess. I'm assuming all this,<br>
but if it is true and you did build your own libqmi without using<br>
--prefix in configure, try to run qmicli like this instead:<br>
<br>
$ LD_LIBRARY_PATH=/usr/local/lib qmicli -p -d /dev/cdc-wdm0<br>
--nas-get-signal-strength ....<br>
<br>
Or, otherwise, install libqmi "on top" of the system-installed one<br>
with --prefix=/usr or whatever your system uses.<br>
