The 2215 will see the Bluetake unit's BT and pair but will not see any profiles that are compatible. The Blue take supports headset/handsfree and A2DP. There is no way to enable the headset/handsfree profile on the 2215 so things like Skype aren't going to work.
You can go to HP and get
http://h18007.www1.hp.com/support/fi...reg_R1002_USEN and enable the A2DP profile. Yea it says 5500, and it's for HPs headphones, but that's the one I could find. It'll work.
