I was wondering, about how many NI sessions can you reliably have going simultaneously if using MultipeerConnectivity to send and receive tokens?

I've been trying to develop an app that implements the NearbyInteraction Framework to connect multiple devices at once. I have been reading through the documentation and following along with the sample code provided by Apple at a WWDC20 session, which can be found here: https://developer.apple.com/documentation/nearbyinteraction/implementing_interactions_between_users_in_close_proximity I have been attempting to adapt this code to create concurrent NISessions for multiple connections, but without success. The use of the MultipeerConnectivity framework seems to be working fine; when I start one session, the program works perfectly, however, if I attempt to add a third phone (creating a second session), after receiving the token from this new user, the initial session becomes invalidated and stops working. I'm not sure how to go from the sample code provided to a program that can create more than one session at a time, and was hoping for some help to point me in the right direction. Thanks!

Hello, I just wanted to confirm.. If I were to start 2 simultaneous NearbyInteraction sessions with 2 peers, it would generate a unique token for me to send to a peer for each session, correct? Thanks!

if I want to create a NIDiscoveryToken object not use MultipeerConnectivity, how to do it?

Does the Nearby Interactions API allow connection with DWM1001 UWB modules?

Are there any rule-of-thumb accuracy specifications we can use to plan our Nearby Interaction apps? For example, in ideal cases (phones are facing each other with clear line of sight), what sort of distance measurement accuracy can we expect? What about the refresh rate for position updates? 10Hz? Similarly, when conditions are less than ideal (for example, devices are not facing each other in the antennas beam pattern), does the distance accuracy degrade significantly? I know we'll lose the direction vector. Thanks!

Is it possible like with some android phones, to wake the iPhone up by hovering hand over the phone's screen? Thanks.

Whats the maximum distance in a Nearby Interaction?

Will this API also support other UWB devices other than iPhones, for example interact with an IoT device that has a UWB - Decawave DW3000 chip for IoT applications.

This looks like a really fun & powerful feature! Is it possible to use the new Nearby Interaction between devices owned by the same user? If so, is it possible for the user to grant permanent permission for us to do this instead of repeatedly at the beginning of every session?

Can the new Near By Interactions be used in background mode? Or even terminated mode where the app wakes up when near other devices?
