- The concept of monitoring for a region is to try to detect when we entered the proximity of a region or left the proximity of that region.
- The amount of time to consider that a region has been left is defined in Beacon Scanner Initialize action.
- A region is an abstract concept that can represent a single beacon or a group of beacons. For example if you specify a Region Code for iBeacon and you fill in only the ID1 (UUID) parameter, all the beacons that have that UUID independently of their major or minor IDs will be considered to belong to that region. But if you specify all 3 IDs (UUID, Major and Minor), then the region will actually only target that specific beacon. The same concept can be applied to Eddystone.
- On iOS, for iBeacons you have to specify at lest the UUID, you cannot specify a region that is valid for all beacons.
- On iOS, monitoring is limited to 20 regions.
- On iOS, for iBeacons, the permission for "Location Always Usage" is required.
- If you call this action with a region code that already existed, that region will be replaced by this one.
