# RadarBeacon

> Represents a Bluetooth beacon with UUID, major, minor, and RSSI information.

`RadarBeacon` represents a Bluetooth beacon. Learn more about [Beacons](https://radar.com/documentation/beacons).

## Properties

<ResponseField name="_id" type="String">
  The Radar ID of the beacon.
</ResponseField>

<ResponseField name="__description" type="String">
  The description of the beacon. Not to be confused with the `NSObject` `description` property.
</ResponseField>

<ResponseField name="tag" type="String">
  The tag of the beacon.
</ResponseField>

<ResponseField name="externalId" type="String">
  The external ID of the beacon.
</ResponseField>

<ResponseField name="uuid" type="String" required>
  The UUID of the beacon.
</ResponseField>

<ResponseField name="major" type="String" required>
  The major ID of the beacon.
</ResponseField>

<ResponseField name="minor" type="String" required>
  The minor ID of the beacon.
</ResponseField>

<ResponseField name="metadata" type="NSDictionary">
  The optional set of custom key-value pairs for the beacon.
</ResponseField>

<ResponseField name="geometry" type="RadarCoordinate">
  The location of the beacon.

  <Expandable title="properties">
    <ResponseField name="coordinate" type="CLLocationCoordinate2D" required>
      The coordinate.
    </ResponseField>
  </Expandable>
</ResponseField>

<ResponseField name="rssi" type="NSInteger" required>
  The RSSI (Received Signal Strength Indicator) of the beacon, or 0 if not available.
</ResponseField>

## Methods

### arrayForBeacons

```objective-c theme={null}
+ (NSArray<NSDictionary *> *_Nullable)arrayForBeacons:(NSArray<RadarBeacon *> *_Nullable)beacons;
```

Converts an array of `RadarBeacon` objects to an array of dictionaries.

### dictionaryValue

```objective-c theme={null}
- (NSDictionary *_Nonnull)dictionaryValue;
```

Returns the dictionary representation of the beacon.

## Example

```swift theme={null}
let beacon: RadarBeacon = event.beacon
let beaconId = beacon._id
let beaconDescription = beacon.__description
let beaconTag = beacon.tag
let beaconExternalId = beacon.externalId
let beaconUuid = beacon.uuid
let beaconMajor = beacon.major
let beaconMinor = beacon.minor
let beaconMetadata = beacon.metadata
let beaconGeometry = beacon.geometry
let beaconRssi = beacon.rssi
```

```objective-c theme={null}
RadarBeacon *beacon = event.beacon;
NSString *beaconId = beacon._id;
NSString *beaconDescription = beacon.__description;
NSString *beaconTag = beacon.tag;
NSString *beaconExternalId = beacon.externalId;
NSString *beaconUuid = beacon.uuid;
NSString *beaconMajor = beacon.major;
NSString *beaconMinor = beacon.minor;
NSDictionary *beaconMetadata = beacon.metadata;
RadarCoordinate *beaconGeometry = beacon.geometry;
NSInteger beaconRssi = beacon.rssi;
```

<Note>
  The RSSI value indicates the signal strength of the beacon. Higher values (closer to 0) indicate stronger signals, while lower values (more negative) indicate weaker signals.
