I must admit to being a beginner with Bluetooth technology, my simple theory is if it is cheap give it a test out, if it does not work return it for a refund. So aprt from the USB bluetooth give the 3.5mm jack plug Bluetooth a try, practically every piece of musical equipment has that installed. Come back with some detail of what you want Bluetooth to do and I will offer some help.
I'm using it in conjunction with an raspberryPi to experiment iBeacons. iPhone and iPad recognized the device without a hich. haven't still tried transferring files or things like that, but there shoyuld be really no problem
