I want to develop a demo of uwb which can be run across multiple iPhones. In the video of WWDC it is said that for each device, a distinctive NISession is needed. I tried to generate two different NISessions, but I found that the discoveryToken for each session is different. That made me confused because I thought each device should have only one single token. Can anyone tell me how to manage multiple UWB connections at the same time? Thanks in advance.

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

I found that my 2nd generation siri remote does not work properly with the apple tv simulator. The central button and the back button works, but the 4 directional buttons and the sliding gestures do not work. However my 1st generation siri remote work normally. Does anyone know what the problem is? Thanks in advance.
