A1502 bluetooth hardware problem?

Hi,

I recently started to use bluetooth on my MacBook Pro 13'“ Early 2015 (didn’t need it before), so I can’t say when these problems started.

However, the problem is that bluetooth keeps behaving strange. Sometimes I can’t turn it off or on (button is greyed out OR it just does nothing). Devices also don’t properly reconnect after sleep and if want to connect to them in the preferences, it just freezes for a moment and the beachball is showing.

It seems like a lot of people have these problems and they suggest various fixes (delete bluetooth plist, reset bluetooth module, reset SMC, reset *RAM, …). All of these are only a temporary fix, the problems come back.

So is it possible that this is a hardware problem? I can find a lot of people having these issues, but nobody with a proper solution. Has anybody fixed this by replacing the AirPort card? I would definitely do that, but not without *someone* having success with this method.

Thank you!
