I have a new gen 6 Bradshaw (Michael Kors) I am connecting to my iPhone iOS version 17.1.1 and both Bluetooth buttons are turned on for both watch and phone and It says iPhone not connected under the setting button under connections >Bluetooth> iPhone disconnected. But when I go to the iphone and look under the Bluetooth Settings, It say connected. Also the find my phone icon is grayed out.
All Android Wear powered watches should work on iPhone. Download the Android Wear app and follow the prompts on watch and app to get connected.
There are youtube videos available. Google for How to connect smartwatch to iPhone.
