development of 2nd siri remote

I'm trying to use the 2nd siri remote as the controller for my app, however I have encountered several problems.

  1. For the 1st siri remote, I can get the raw data of the trackpad, however the 2nd siri remote does not output the coordinate of the touch points. I want to know how can I get access to the raw data of the trackpad?

  2. I want to know how to get the button events of the remote. I have tried the method introduced in this tutorial https://developer.apple.com/news/?id=33cpm46r, but cannot get the button event.
