I just bought a Pageflip Firefly pedal to use with the MobileSheets app, but I can't get it to work with my TF-101. It pairs and connects OK (the Profile says it is an Input Device), but no "keystrokes" seem to be getting received by any applications. As an experiment, I tried pairing the pedal with my phone (a Samsung Galaxy S5) and on that I can see the keystrokes coming through to various applications, such as text editors, so I'm pretty sure the pedal is working OK. I've tried it docked and undocked, with wifi switched on and off, etc. The keyboard (in Settings) is set to "ASUS keyboard - ASUS English (UK) keyboard", but I've tried it with Google keyboard as well.

The Transformer is running Android 4.0.3 with Bluetooth 8.30 from ASUS. I don't think there is anything unusual about the setup, except that I rooted it in order to run some encryption s/w (EDS).
