Hello Everyone!
I Am currently trying out the U1 chip on iPhones using the NearbyInteraction framework. I wanted to ask If there is a way that I can send custom data using the NISession.
Sending Custom message (U1Chip) Nearby Interaction
No, the NISession is only used to get you data regarding the position of the other device. NearbyInteraction framework works only in one direction (sending spatial information from the device to your phone). If you want to send the data to the other device (iPhone, Apple Watch, or the UWB Accessory) you need to use standard communication frameworks: CoreBluetooth, Multipeer Connectivity, etc.
