Thank you for your post.
RangeBeacons returns the Beacon information from iOS. Proximity returns the estimated distance in proximity zones: 1-immediate, 2-near, or 3-far. When the proximity value is 0, it simply means iOS could not determine the zone. The beacon can be in any of the zones, and not necessarily far (3).
would you be willing to share the simple example you referenced? i am new to filemaker and am having trouble getting FM to insert beacon info in my table.
