Trouble with EM7565 startup...
-
@Ed-Sutter And to be safe if you're in station mode I would set your ssid and pass to dummy values, i.e
voxl-wifi station tmp tmpbecause I've seen in the past wherewlan0will try to bring itself back up after you manually force it down.@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 lineThat (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 172.26.38.1Looks 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? -

@Ed-Sutter I'm speaking specifically of VOXL, not your host computer, but it's the same idea. It's the actual Linux device driver for that piece of hardware. For example: https://gitlab.com/voxl-public/system-image-build/apq8096-kernel/-/blob/main/drivers/net/usb/qmi_wwan.c#L772
@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?
