I gave up on bluetooth a decade ago; it just can't be relied upon. Once upon a time, we wondered: "wouldn't it be lovely if devices could just talk to each other, wirelessly, and we didn't have to fuss around with cables?" Now I know: "isn't it lovely that I can just make things definitely work, for sure, with cables, and I don't have to fight with the endless flakiness of some hacky wireless protocol?"
