Public Methods

Method	Description
BeaconCodeToString ( ushort beaconCode ) : string	Converts the given beacon code to string.
BeaconFromBluetoothLeAdvertisementReceivedEventArgs ( BluetoothLEAdvertisementReceivedEventArgs args ) : Beacon	Constructs a Beacon instance and sets the properties based on the given data.
BeaconFromByteArray ( [ data ) : Beacon	Constructs a Beacon instance and sets the properties based on the given data. The expected specification of the data is as follows: Byte(s) Name -------------------------- 0-1 Manufacturer ID (16-bit unsigned integer, big endian) 2-3 Beacon code (two 8-bit unsigned integers, but can be considered as one 16-bit unsigned integer in little endian) 4-19 ID1 (UUID) 20-21 ID2 (16-bit unsigned integer, big endian) 22-23 ID3 (16-bit unsigned integer, big endian) 24 Measured Power (signed 8-bit integer) 25 Additional information byte (optional) For more details on the beacon specifications see https://github.com/AltBeacon/spec The minimum length of the given byte array is 25. If it is longer than 26 bits, everything after the 26th bit is ignored.
BeaconFromDataSection ( BluetoothLEAdvertisementDataSection dataSection ) : Beacon	Constructs a Beacon instance and sets the properties based on the given data.
BeaconFromDataSectionList ( IList dataSections ) : Beacon	Constructs a Beacon instance and sets the properties based on the given data.
BeaconManufacturerData ( ushort manufacturerId, ushort beaconCode ) : BluetoothLEManufacturerData	Creates a BluetoothLEManufacturerData instance based on the given manufacturer ID and beacon code. The returned instance can be used as a filter for a BLE advertisement watcher.
BeaconToSecondDataSection ( Beacon beacon, bool includeAuxByte = false ) : BluetoothLEAdvertisementDataSection	Creates the second part of the beacon advertizing packet. Uses the beacon IDs 1, 2, 3 and measured power to create the data section.
CalculateDistanceFromRssi ( double rawSignalStrengthInDBm, int measuredPower ) : double	Calculates the beacon distance based on the given values. http://developer.radiusnetworks.com/2014/12/04/fundamentals-of-beacon-ranging.html
DataSectionToRawString ( BluetoothLEAdvertisementDataSection dataSection ) : string	Converts the data of the given BluetoothLEAdvertisementDataSection to a string.
FormatUuid ( string uuid ) : string	Formats the given UUID. The method also accepts strings, which do not have the full UUID (are shorter than expected). Too long strings are truncated. An example of a formatted UUID: de305d54-75b4-431b-adb2-eb6b9e546014
ManufacturerIdToString ( ushort manufacturerId ) : string	Converts the given manufacturer ID to string.
UuidToAdvertisementBytePattern ( string uuid, ushort manufacturerId, ushort beaconCode ) : BluetoothLEAdvertisementBytePattern	Constructs a BluetoothLEAdvertisementBytePattern instance from the given UUID. UUID doesn't have to be full 32 hex digits, but length needs to be even.

Private Methods

Method	Description
ChangeInt16ArrayEndianess ( byte byteArray ) : byte[]	Switches the endianess of the given byte array so that every two bytes are switched.
HexStringToByteArray ( string hexString ) : byte[]	Converts the given hex string to byte array.
