If the Jacquard Tag has been previously paired with another phone, it always performs whitelist advertising. In this mode, a Jacquard Tag is “visible” to other phones but cannot be paired with other phones. For example, if the Jacquard Tag has been paired with Phone A, then Phone B and C can “see” the Jacquard Tag but they cannot pair with it. Only Phone A can connect to the Jacquard Tag.
