@Emil Thanks for your answer. Actually very helpful
I connect my flic with my Ipad through your App. It is giving a signal of keyboard buttons, like Enter and ESC.

Hello! I have an Airturn device connected to my iphone/ipad and the button triggers the action instantly with an older Bluetooth version. The Flic 2 has compared to it a big delay. Is there any way of reducing this? Why is it so with a newer version of Bluetooth?
