I purchased the full KX3 Companion app from Amazon for my brand new Fire. Of course, Amazon tells you it's not compatible with your Fire after you've paid for it.
I understand, traditionally, the KX3 Companion hasn't worked with Amazon tablets due to the lack of USB hosting. However, I had hoped to test a new Fire with the KX3 Companion using Bluetooth mic, phones and ACC1 (RS232) connections (i.e., no wires). I know Andrea has experimented with Bluetooth. I'm not sure what's in the current code base.
Is there any way to get the KX3 Companion on a Fire?
