To create a Connection between two people, who each have their own charm, each person would need to pair their charm to their own device.
The order we recommend you follow is:
(1) Person #1 pairs their charm to their phone and creates their account
(2) Person #2 scans the code on the packaging of Person #1's charm and creates their account
(3) Person #2 goes to their Settings and taps "Add Charm" in the Connection that has been created
(4) Person #2 pairs their charm with their phone
(5) Both charms are now connected to the same message feed and each person's charm is paired with their own device
