It worked for me, or at least it used to. At one point in time, I had an Acer Iconia Tab using BT to talk to the OBDII and my Samsung Galaxy S talking to the phone Bluetooth. I think I may have confused it though, when I had my Samsung as a hotspot, and tried to use my Acer's copy of Skype to talk to a friend. I'm all messed up now, looking for answers on how to start all over again.
It is hard to understand what you did. IMHO, the good start will be to delete all BT pairing info on all devices and start from the scratch.
Reviving old thread just to mention that for me, in October 2017, Tactrix Openport 2.0 seems to work extremely well with my Gen 3. -Chap
