Bluetooth beacons use Bluetooth Low Energy proximity sensing to transmit a universally unique identifier [1] picked up by a compatible app or operating system. The identifier and several bytes sent with it can be used to determine the device's physical location, [2] track customers, or trigger a location-based action on the device such as a check-in on social media or a push notification .
The way a device uses Bluetooth depends on its profile capabilities. The profiles provide standards that manufacturers follow to allow devices to use Bluetooth in the intended manner. For the Bluetooth Low Energy stack, according to Bluetooth 4.0 a special set of profiles applies.
For example, when connecting a mobile phone to a Bluetooth headset, SDP will be used to determine which Bluetooth profiles are supported by the headset ( headset profile, hands free profile, advanced audio distribution profile, etc.) and the protocol multiplexer settings needed to connect to each of them.

Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 metres (33 ft).

iBeacon is based on Bluetooth low energy proximity sensing by transmitting a universally unique identifier [4] picked up by a compatible app or operating system. The identifier and several bytes sent with it can be used to determine the device's physical location, [5] track customers, or trigger a location-based action on the device such as a check-in on social media or a push notification .
SBC (codec) SBC, or low-complexity subband codec, is an audio subband codec specified by the Bluetooth Special Interest Group (SIG) for the Advanced Audio Distribution Profile (A2DP). [1] SBC is a digital audio encoder and decoder used to transfer data to Bluetooth audio output devices like headphones or loudspeakers.
