  • Request for testing and feedback with Bluetooth on Android 14 QPR2 GrapheneOS

GrapheneOS as I reported 4 days ago my OBDLink MX+ (non-BLE) will pair but refuse to connect to Pixel 8 on GrapheneOS since 2024030800. The update next day did not improve on that. Socket.connect() takes some time, then returns:

Connection failed: read failed, socket might closed or timeout, read ret: ‑1

Testing on a Pixel 8 Pro with latest QPR2 stock (version details mentioned above) works flawlessly.

There has been a similar report yesterday of someone describing the exact same behavior on an older Pixel device and a similar OBDLink non-BLE device, just some posts above.

      I forgot to state the build: 2024031100

      Need to see a system log. To capture it, try to connect to the affected Bluetooth device again, then go to Settings -> System -> View logs -> Share (or Save). Send the log file to one of the following places:

                muhomorr I disabled developer settings, enabled "Notify about system process crashes", forgot the Bluetooth device, factory reset the watch, rebooted the phone, waited a bit for stuff to finish starting up, then went through the process of re-pairing the watch and signing in to all the accounts.

                After pairing, waiting for the watch to finish starting everything, and confirming that it was actively paired with the Galaxy Wearable app, I went into the phone's Bluetooth settings and tapped the watch's Disconnect button. It didn't actually disconnect though. Rather than putting the phone in airplane mode, I turned the watch's Bluetooth off and back on. A second after re-enabling it, the same behaviour on the phone resumed; rapidly moving between Other devices and Saved devices.

                Watch model: SM-R950
                Phone model: Pixel 6
                Hardware version: MP1.0
                Hardware SKU: GB7N6
                GrapheneOS build num: 2024031100

                I'll send my log file to your Discord after I look through it for sensitive info I'm not comfortable sharing.

                  We're going to be making a new release today with a workaround for the remaining upstream memory corruption bugs introduced in the Bluetooth app in QPR2. We can't do anything about old insecure devices which no longer work due to security improvements which also applies to the stock OS.

                    Is the Galaxy Watch 6 one of the old, insecure devices? Meaning we'll have to wait for Samsung to release an update that fixes it?

                        No! The Galaxy Watch 5 and 6 models received a security update yesterday. I also spoke with Google and Samsung. The security firmware is up to date.

                          Please make sure to do this:

                          Before testing, please disable developer options, enable "Notify about system process crashes" in Settings > Security and reboot.

                          We haven't gotten a crash report tied to the Galaxy Watch issue yet, although it might not involve a crash.

                            We're coming up with some workarounds to ship in the next release. We want to try to provide them in a way that users can help us determine the problem through flipping some toggles. We can then try to act based on the knowledge gained from that to fix the actual problem.

                              Pixel 7 Pro - Graphene Build # 2024031100

                              Bluetooth Devices broken since QRP2:
                              OBDLink MX+ - Worked well before QRP2, but now I am unable to connect to this device.

                              Bluetooth Devices operating normally since QRP2:
                              Galaxy Watch 4 Classic
                              Galaxy Buds Live
                              Pioneer DEH-X6900BT

                              Before testing, please disable developer options, enable "Notify about system process crashes" in Settings > Security and reboot.

                              Tried this, but haven't been notified of any crashes or logs. I'm not sure how to generate a relevant log
