Bluetooth and Camera on N7 LTE (deb) not working

j0b314 · 13 Jan 2020, 07:44

Hi,

thank you for this great software! Currently I am facing 2 issues with ubuntu touch on the google nexus 7 lte (deb). The issues are in stable and nightly:

Bluetooth is not working
Camera is not working

Is there a way to bring this to work. Or maybe I have an error in my configuration.

Thank you very much!

Hi All,

Yes it's a great software, many thanks !

Same problem here. I can't activate bluetooth on my Nexus 7 LTE.

Regards.

@j0b314 , @LionelM
It seems hardware related.
I suspect Nexus7 users have the same problem, but I cannot confirm this.
It would be nice to have information from other users.

You can check the bug tracker for your tablet and open an issue for it.

I can confirm the same problems with my Nexus 7 2013 LTE deb - along with also the side stage features also not working. My take on this, given that these are 7 year old devices, that it would be a waste of the core team's time to try to make device specific for these, and that instead it would better if they focused more on getting more recent tablet hardware (e.g PineTab) working better with UT.

I can confirm the same issue.

Given the nexus 7 allows similar experience than the nexus 5 (full convergence performance with hdmi support) I think it will be beneficial for the core team to give it a go solving this one so this tablet can be listed as recommended device.

Its cheap to buy and performs really well.

My 2 cents.

Bluetooth can be done by remounting as rw and copying /etc/init/bluetooth-touch-flo.conf to /etc/init/bluetooth-touch-deb.conf after updating the kernel to a "flo"-based one, unfortunately copying the upstart unit alone isn't enough to make bluetooth start. (It might be worth me continuing my custom kernel project just for the deb)

I haven't tested Camera yet, I'll check that here in a little bit after I get my setup back up (I had flashed it as a Flo to see if that corrected the external display scaling, spoiler, it didn't.)

Edit: Camera doesn't work for me even with a Flo kernel, something deeper is involved in that issue, but I am attempting to compile an issue list and workaround/observation list over in https://forums.ubports.com/topic/6056/nexus-7-lte-general-bugs-problems

I think what's needed is to go through the entire codebase, find quirks and hacks for the Flo and make them also run for the Deb, as 99% of the hardware is exactly the same (the Flo only misses the LTE modem and Sim Slot) and even run the same bootloader/baseband images.

@tonoxis - thanks so much for your work on this. Maybe I will be able to actually have my Nexus 7 deb be a useful device once you are done. Now - just need to remember where I put it.

Best regards,

@totalsonic I'd like to try for that, Honestly I'd like to use my Nexus 7 Deb as a cellular workstation, even have the SlimPort dock for it if the problems with SlimPort can be figured out.

If the kernel helps, please feel free to help contribute to the issue list and post any workarounds you may find.
