Pairing establishes credentials on the Jacquard Tag and the phone for mutual authentication. Pairing DOES NOT imply a Bluetooth connection. Pairing is similar to storing the Wi-Fi password for a Wi-Fi access point on a Windows or Macintosh computer. Just like the Windows or Macintosh computer must connect to an access point, Jacquard Tag must also connect to the phone for the TEAM FX app to talk to the Jacquard Tag.
