Like GLRawson, my connection tend/ to drop out when I’m moving, at any speed or location.
Typically, the Bluetooth connection drops at exactly 40 seconds and re-connects shortly thereafter without the call dropping. Curiously, more often than not, the phone remains connected thereafter.
Over the weekend I’ve tested on other devices and don’t have any BT connection problems with other devices such as my AirPods Pro (1st Gen) and Anker Soundcore portable speaker, both of which I have tested with calls and music both sitting and moving around.
Further, I stream Spotify over Bluetooth in the car via a ViseoO Tune2Air without problems.
i haven’t tried my AirPods whilst driving yet - so can try that later to see if moving between cells is an issue.
In my reading, it does feel like an 15P/15PM issue related to lower data rate connections like calls, and not streaming media devices. That doesn’t explain why others are having problems though.
All very odd …
