Fw: question about qmicli

[Galo Irarrazabal]

Hi,

the distribution of the linux i'm using is linux raspbian buster (the last version) in a raspberry pi CM3+
if i specifically put the path in /usr/lib all commands work ok and withput errors.

in respect to the use of dms-noop, i do this because are many commands with wds, dms and nas services
inside a while True:  (really this is a thread that call this services evere 10 seconds)

i hace another thread that make pings to the google dns 8.8.8, and check if the connection is alive
if the thread lose the connection, power cycle the modem and execute a wds service for
connection

sudo  LD_LIBRARY_PATH=/usr/lib qmicli -p -d /dev/cdc-wdm0 --device-open-net='net-raw-ip|net-no-qos-header' --wds-start-network="apn='APN',ip-type=4" --client-no-release-cid

in the case of wds service,  What is the right way to get CID and  not release them. i need to execute a wds-noop first and then execute the connection?

and what happen with the CID when the connection are losed? i need to request another CID with wds-noop or i can reuse the existent ?

thank's and best regards
Galo

No, you shouldn't leave that setup like that, qmicli is still crashing.

It looks like your distribution isn't using /usr/lib by default for
libdir, which is why this is breaking like this. Instead of the
configure with only --prefix, do the following:

// clear your previous installation that you did with --prefix=/usr
$ sudo make uninstall

// now configure also specifying --libdir, e.g. I would bet you're
using Ubuntu or similar, so:
$ ./configure --prefix=/usr --disable-static --libdir=/usr/lib/x86_64-linux-gnu
$ make -j8 && sudo make install

// and now retry the qmicli command, e.g.
$ sudo  qmicli -d /dev/cdc-wdm0 -p --nas-get-signal-info

You could allocate a DMS client also for those, e.g. using --dms-noop
instead, but well, if it's only 2 commands and you're not going to
poll them over and over, you could just run them without the explicit
client allocation logic.
