Hello @estimote Thanks a lot for taking the time to answer me. Your idea is totally what is planned in our team. It is true that doing some scheduling over those 5 sessions would allow us to have more iPhones connected (and will drain much less battery). However, my question was really related to the multicasting possibility of the UWB protocol, which allows to have 8 devices per session, for a total of 40 devices receiving UWB ranging data. It would be useful in very busy places. Thanks!
