Trouble with EM7565 startup...

Ed Sutter

@tom One thing I just noticed...
If I boot up without an LTE modem, then /etc/resolv.conf is:

# Generated by dhcpcd from wlan0
# /etc/resolv.conf.head can replace this line
domain myfiosgateway.com
nameserver 192.168.1.1
# /etc/resolv.conf.tail can replace this line

That (above) makes sense. That's my ISP (Fios) and wifi subnet in my home.
If I boot up with the LTE modem, then /etc/resolve.conf is:

nameserver 172.26.38.1

Looks like something in the modem startup overwrites /etc/resolv.conf. The script "enable-dns.sh" is called by voxl-modem-start.sh, but it only writes to /etc/resolve.conf if it doesn't already exist (plus it writes 8.8.8.8, which apparently is Google dns).
Any idea how this is being written?

@tom I'm starting a new thread on this...

@Eric-Katzfey Somehow this slipped through the cracks... I just looked in that file and I don't see the VID/PID of the EM7565 listed. So a couple of questions:

What does this mean?
Do you know what is involved in getting it listed?

I have the latest driver files from Sierra Wireless, and they do have what I need. Is this a module that I can update on VOXL?

@Eric-Katzfey @tom Digging a bit deeper into this, I see that the voxl-build procedure does patch the qmi_wwan.c file, and after the patch, the VID/PID for EM7565 is in there. On one hand this is good news because it implies that the kernel does have support for the modem I'm trying to use; however, its not-so-good news for me because running with that modem has not reliable on VOXL.
Aside from verifying that I am actually running the same version on my VOXL-Flight-Deck as is being built in voxl-build (see below), I'm at a loss regarding other things to do to debug this. Any thoughts on this?
Following is the output of voxl-version on my board:
