My device is a medical device (Accu-Chek Insight reached via the app Android APS), worked before the update without problem, currently not working ending in error "Connection failed" and pairing unsuccessful, on Pixel 7

doffactory We think that your device may not be working due to upstream security fixes which would mean that this is also the case on stock OS.

I understand that this is a lot to ask but we do not have this specific Bluetooth device. Would it be possible for you to backup your data and flash stock OS on the latest Android 14 QPR2 release to see whether your device works there? It likely won't, but confirming that would be a big help to the team.

doffactory Would be good to confirm if this works on the latest update for you.

matchboxbananasynergy I asked the same question on the app dev's page: https://github.com/nightscout/AndroidAPS/issues/3259

To be honest, I believe this might be indeed an issue on the stock Android 14 QPR2 release as well, although unconfirmed, and at the moment I do not have much time to completely reflash the phone with 3 accounts due to work commitments in the upcoming 2-3 weeks. Hopefully other P7 users will be able to confirm whether the stock firmware suffers with the same issue

GrapheneOS

If you do make backup for this, make sure to enable the device-to-device backup mode toggle to backup much more app data. You should back up your home directory yourself and backup Signal/Molly via their own backup system. Also, OS backup service is per-profile.

P8 in current Alpha, Bluetooth connection tested with the following devices: Bluetooth Speaker (UE Megaboom, sound), 2 Headlhones (Ultrasone Lapis, Ultrasone Isar, both sound), Car Stereo (Smart Media Systems, sound), Notebook (HP Spectre x360, File Transfer), Hifi Receiver (Denon AVR-X220W, Sound), Omron RS7 Blood Preasure Measurement. All works well, no crashes or other issues noted).

I haven't tested all Bluetooth devices yet, but so far headphones seem fine.

The one thing that has stopped worked with Graphene's 14QPR2 is my Pebble Time watch (via GadgetBridge). It worked fine before the update, but now reports (in GadgetBridge) "Connecting" and then "Waiting to reconnect" and then loops back to "Connecting" infinitely and never actually manages to connect.

emacsomancer I have this same issue with my Pebble Time and my Pixel 7 after the QPR2 update. I also have a pebble2 HR which does pair and work just fine weirdly. I have not tested with the stock Pixel 7 QPR2 update, only with GrapheneOS since I don't want to reflash my phone right now.

There's a sortof similar issue posted on the gadgetbridge gitlab https://codeberg.org/Freeyourgadget/Gadgetbridge/issues/3596 . Unconfirmed if it's related or not though.

Got issues connecting a classic bluetooth (non-BLE) ELM327 OBD dongle (OBDLink MX+). Pairing works, but then apps cannot connect. Got no crash reports. Test on non-GrapheneOS phones were successful.

My phone (Pixel8) is on latest GrapheneOS 2024030800
I'm quite sure it worked when I initially installed GraphenOS about 2 months ago.

A bunch of other BT devices still work flawlessly on same phone (e.g. headphones, car HFP, ...)

I can confirm these devices working:

1more Comfobuds Pro
Sabbat E12 Ultra
Nothing Ear (2)
PineTime watch (via Gadgetbridge)

The PineTime seems to take a lot longer to connect after starting Gadgetbridge (about 50s compared to about 3 seconds before) but reconnecting is fast as ever.

No crashes; works fine on a Pixel 8:

Jabra Elite Active 75t earbuds
Ironside 2018 BT speaker

These devices do not support Bluetooth LE.

GrapheneOS Pixel 7 Pro, Shockz OpenFit, Bluetooth audio in calls works but the microphone does not always work and sometimes drops put. Have to manually reselect Bluetooth device in the call for the microphone to start working again.
Edit: using 2024030800 I've had the issue occur today after updating but I've been experiencing the issue for over a month now and only just made an account here to try and figure it out.

Bluetooth not connecting to smart watch.

ErnestThornhill

p0well34 You're going to have to elaborate. That doesn't provide much detail regarding your issue.

Psymos

Galaxy watch6 classic doesn't connect.

If i open my bluetooth screen it seems to keep trying to connect. It cycles rapidly from saved devices to the top (where the connected devices normally show)

Same thing.

rlneyhard

Pixel 8 Pro with Galaxy watch6 doesn't connect.

In Bluetooth settings it appears to be connected but it won't connect in the wear app.

p8 Pro running 2024030800.

Religiously use apple airpod pros new and old generations and have never had issues on any release.

I use a 2nd profile as my daily driver and noticed when switching to the Owner profile sometimes get a "Bluetooth has crashed" notification on the Owner. Will try to save logs next time but doesn't happen often.

GrapheneOS

We've found and fixed an upstream Android 14 QPR2 use-after-free bug with Bluetooth LE audio discovered via our hardware memory tagging support on the Pixel 8 and Pixel 8 Pro. It is likely causing issues on all devices, not only 8th gen, it was just easy to fix it via MTE catching it as it happened. We'll be making a new release later today with our fix. This thread we posted across platforms has more info (note it was posted before we found and resolved the issue):

No problems with my Apple AirPods Pro (2. Gen.) ever (using with Pixel 7 Pro and 8 Pro).
Now with the newest GOS version 2024030800. Works very well.
Thank you for the great work!

Jabra Elite Active 75t earbuds working fine before the update and on the current build (2024030800).

GrapheneOS

There's a new release in the Alpha channel now:

https://discuss.grapheneos.org/d/11397-grapheneos-version-2024030900-released

It has a fix for an upstream Bluetooth bug which a user has confirmed fixes their issue with Samsung Galaxy Buds2 Pro in BLE mode.

doffactory

GrapheneOS Sorry for the ignorance, but when can we expect this to be in stable?

doffactory

GrapheneOS I tried this update, and unfortunately it did not fix my bluetooth issue with the said medical device, same error "Connection failed" when it requests pairing (the pairing code does not appear on the phone)
