External Keyboard Helper can detect the commands from Yuri's controller board if I connect the controller board to my nexus 7 through an OTG.
External Keyboard Helper does have the option to select bluetooth, but it didn't detect the bluetooth module.
Maybe there is some setting I need to adjust in External Keyboard Helper?! I'm just way to busy with the family to have a little break to sit down and play with it.
As for the setup, yes:
Controller board+idrive via bluetooth module => android
(wirelesd but slow 1 - 1.5 second due to emulating dpad)
Or
Controller board+idrive via USB port on the controller board => android (fast, since it's not emulating rather remapping but wired)
