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).
Bluetooth Low Energy ( Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart [1]) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) [2] aimed at novel applications in the healthcare, fitness, beacons, [3] security, and home entertainment industries.

Video conferencing profile (VCP): This profile is to be compatible with 3G-324M, and support videoconferencing over a 3G high-speed connection. Tempow Audio Profile (TAP): this new audio profile was presented at Bluetooth World 2017 in Santa Clara. It enables new audio functions, upgrading current A2DP profile.
lwBT is an open source lightweight Bluetooth protocol stack for embedded systems by blue-machines. It acts as a network interface for the lwIP protocol stack. It supports some Bluetooth protocols and layers, such as the H4 and BCSP UART layers. Supported higher layers include: HCI, L2CAP, SDP, BNEP, RFCOMM and PPP .
The Bluetooth protocol RFCOMM is a simple set of transport protocols, made on top of the L2CAP protocol, providing emulated RS-232 serial ports (up to sixty simultaneous connections to a Bluetooth device at a time). The protocol is based on the ETSI standard TS 07.10. RFCOMM is sometimes called serial port emulation.
Windows Phone BTF support is available from Windows Phone 7.8, but is limited to the transferring of pictures, music and videos via a 'Bluetooth Share' app. Feature additions [ edit ] Microsoft keeps a site where people can submit and vote on features they would like to see added to Windows Phone.
The Bluetooth Special Interest Group ( Bluetooth SIG) is the standards organization that oversees the development of Bluetooth standards and the licensing of the Bluetooth technologies and trademarks to manufacturers. The SIG is a not-for-profit, non-stock corporation founded in September 1998. The SIG is headquartered in Kirkland, Washington .
Bluetooth beacons use Bluetooth Low Energy proximity sensing to transmit a universally unique identifier 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 ...
