Ok, so you wrote, "I get the error until I force-quit the H9 Control app, and relaunch it. Then everything is fine until the next time I connect the pedal."
So, you get the same connection error that PBS posted above or does something else happen?
I also don't understand what you meant by everything is fine until the next time I connect the pedal. Do you mean that if your iOS device goes out of range of your H9 and then comes back into range and you reconnect via Bluetooth then you have to fore quit the app to get it to connect to the pedal?
