Hello,
I've been using one BLE connected device (speedometer) without problems for more than a year with two Pixels (7).
I allowed one to update to 2024102100 - with the effect that BLE connection stalls some seconds after a successful initial connection.
After the app reports that connection has ended, the BLE-scanning dialog of the app doesn't show the device in question anymore.
Dis- and reenabling bluetooth radio via quick-tile has the effect that BLE-scan finds the device once again, but problem cycle lopps...
I don't have any other BLE devices to test with the A15 updated pixel (7), but the one BLE device I have still works flawlessly on the not-updated Pixel (7). So the regression is not caused by a faulty device. Maybe incompatible with any Android 15 changes? Or a general Android 15 BLE issue?
