Thanks Saleh. That means your problem is a bug in the bcmwl driver.
bcmwl seems to not implement bluetooth coexistence at all, so its own

Interesting. I installed 17.10 and Bluetooth worked so much better than it had

Indeed it is understandably disappointing, but you need to also consider
that many/most of us have never experienced any such skipping. And if
