In my experience, bluetooth still is some distance away from being a perfect and reliable science. I know that's not a solution for this one; it's simply offered in the observation that not all bluetooth devices want to play happily. Most do, but other combinations simply refuse to co-operate - and I've persevered in some instances to the point of giving up and reaching for a couple of beers (it didn't work after that either). Don't despair - some things are just not meant to be. But that shouldn't deter you from exploring all options - as you are. Good luck, may success be yours to enjoy ...
