From what I have understood the issue is in the Adventure Controller, which send a, let us say, a not standard signal. I made a test with normal BT keyboard with MRb app. I associated a button of the keyboard to the wheel sensor of the app, and once I started pressing it (simulating the magnet when rhe wheel is spinning), the speedmeter came alive. I opened a ticket in the CI website support page, please do the same you also.
