My client is developing an accessory that will connect to the ANCS of the user's iPhone. I wanted to create an iPhone demo app that can connect to the ANCS of another iOS device. Is this possible with CoreBluetooth? When I connected and listed the services of the other iOS device I didn't see a service with the ANCS service UUID of 7905F431-B5CE-4E99-A40F-4B1E122D00D0.
Connect iOS Device to ANCS of Another
Unfortunately, iOS apps cannot create or consume ANCS services.
This is by design.
