@IgnacioVazquez-Abrams - Is HID is normally for non-audio purposes? I don't think it matters to me its BLE or not - it's more just a matter of whether I can accomplish my purpose. Is there a way to (by looking at diagnostics etc) to see if an individual device (eg the one in the pic above) is AVRCP and/or BLE?

@Majenko Thank you! It's the library that needs bluetooth HID support, not the shield, correct? Or do both need to support it?
