For Android, don’t accept the prompt to let the speaker read your contacts and call history. Seems to stop this nonsense on my speakers.

My dude! I can’t believe this is such a pervasive problem! Pretty much every person that I know who connects their car to their phone runs into this issue especially in the case of couples where both phones are paired and it’s just some kind of headbutting match to see which device randomly wins out, which is guaranteed to be the phone you didn’t want connected. In theory their priority system, but in practice Bluetooth device discovery and the connection process seems rather random.

I wish my car had an option to disable auto connection and a prominently displayed button to explicitly connect to a recent phone upon request.

I wonder if this has anything to do with how the bandwidth is automatically decreased when taking a call vs when you’re just playing audio. Less bandwidth means a slower but more robust connection or something like that?

Pretty good idea! Yeah, maybe the half duplex codec can connect with a weaker signal.

Or something. I don’t know that much about the protocol.

I don’t think BT devices do frequency hopping. The audio bandwidth is reduced just because the mic signal is added and has to share the connection. There’s no change on the physical connection.

(Now, it would be great if there was some frequency hopping and your phones could reserve a full FM channel instead of messing with digital compression.)

That decreased bandwidth would still help to maintain a digital connection though, wouldn’t it? There’s be a weaker and slower connection as the devices get further apart, so I was thinking less demand on the connection would keep them from dropping it.

I don’t think it’s the same as what you meant exactly, but I looked it up and Bluetooth does hopping between 2.402 and 2.480 GHz.
