sorry to awake a semi-dormant thread
I just received an iCade Core system, and attempted to pair it with the Kindle Fire HD. I was UNABLE to get this to work - while the device did recognize the peripheral by name, attempting to pair the device (which required me to enter a 6 digit key, followed by the enter key, on the device) was unsuccessful. I did some poking around on the ION forums and everyone with similar issues, regardless of android device, was unsuccessful.
Just wanted to let you know not to grab the iCade Core system if you want to use it w/ your Kindle Fire HD. The more techno-savvy users might be able to work around this issue by changing the bluetooth keyboard profile...or something... but all of that is way outside my scope.
I should get my 8bitty controller in the mail shortly, and will try this with the Kindle Fire HD as well. I've heard this one auto-pairs... here's to hoping.
