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).
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.
Device Manager is a component of the Microsoft Windows operating system. It allows users to view and control the hardware attached to the computer. When a piece of hardware is not working, the offending hardware is highlighted for the user to deal with. The list of hardware can be sorted by various criteria.
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. [ 4]
BlueWiseLE is the Bluetooth Low Energy certified protocol stack software product from Alpwise. It includes the Link Layer [42] and also the Host stack (i.e. upper layers above the HCI). [43] The Link Layer controls the radio and the timing of the Bluetooth communication in three possible chipset configurations: SoC, co-processor or HCI.

Low-density parity-check (LDPC) codes are a class of highly efficient linear block codes made from many single parity check (SPC) codes. They can provide performance very close to the channel capacity (the theoretical maximum) using an iterated soft-decision decoding approach, at linear time complexity in terms of their block length.
