Bluetooth Low Energy Wikipedia. The current Bluetooth Smart logo. Bluetooth Low Energy Bluetooth LE, BLE, marketed as Bluetooth Smart1 is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group aimed at novel applications in the healthcare, fitness, beacons,2 security, and home entertainment industries. 3 Compared to Classic Bluetooth, Bluetooth Smart is intended to provide considerably reduced power consumption and cost while maintaining a similar communication range. Bluetooth Smart was originally introduced under the name Wibree by Nokia in 2. It was merged into the main Bluetooth standard in 2. Bluetooth Core Specification Version 4. Mobile operating systems including i. OS, Android, Windows Phone and Black. Berry, as well as mac. OS, Linux, Windows 8 and Windows 1. Bluetooth Smart. The Bluetooth SIG predicts that by 2. Bluetooth enabled smartphones will support Bluetooth Smart. 5The Bluetooth SIG officially unveiled Bluetooth 5 on June 1. London. One change on the marketing side is that they dropped the point number, so it now just called Bluetooth 5 and not Bluetooth 5. LE like for Bluetooth 4. This decision was made allegedly to simplifying marketing, and communicating user benefits more effectively. 6 On the technical side, Bluetooth 5 will quadruple the range by using increased transmit power or coded physical layer, double the speed by using optional half of the symbol time compared to Bluetooth 4. Bluetooth transmissions compared to Bluetooth 4. Io. T applications where nodes are connected throughout a whole house. 7The Bluetooth SIG released Mesh Profile and Mesh Model specifications officially on July 1. Mesh specification enables using Bluetooth Low Energy for many to many device communications for home automation, sensor networks and other applications. 8CompatibilityeditBluetooth Smart is not backward compatible with the previous often called Classic Bluetooth protocol. The Bluetooth 4. 0specification permits devices to implement either or both of the LE and Classic systems. Bluetooth Smart uses the same 2. GHz radio frequencies as Classic Bluetooth, which allows dual mode devices to share a single radio antenna. LE does, however, use a simpler modulation system. Bluetooth Smart brandingeditIn 2. Bluetooth Special Interest Group SIG announced the Bluetooth Smart logo so as to clarify compatibility between the new low energy devices and other Bluetooth devices. 9Bluetooth Smart Ready indicates a dual mode device compatible with both Classic and low energy peripherals. 1. file size 12. 9 MB runs on Windows 7 Windows 7 64 bit Windows 8 Windows 8 64 bit Windows 2008 Windows 2008 R2 Windows. Bluetooth is an industrystandard protocol that enables wireless connectivity for computers, handheld devices, mobile phones, and other devices. Bluetooth Smart indicates a low energy only device which requires either a Smart Ready or another Smart device in order to function. In the new branding information MAY1. Bluetooth SIG has made one fundamental change. It is phasing out the Bluetooth Smart and Bluetooth Smart Ready logos and word marks and has reverted to using the Bluetooth logo and word mark. The logo uses a new blue color. Target marketeditThe Bluetooth SIG identifies a number of markets for low energy technology, particularly in the smart home, health, sport and fitness sectors. 1. Cited advantages include low power requirements, operating for months or years on a button cellsmall size and low costcompatibility with a large installed base of mobile phones, tablets and computers. Historyedit. The now defunct Wibree logo. In 2. 00. 1, researchers at Nokia determined various scenarios contemporary wireless technologies did not address. 1. The company began developing a wireless technology adapted from the Bluetooth standard which would provide lower power usage and cost while minimizing its differences from Bluetooth technology. The results were published in 2. Bluetooth not working or dont know how to set it up Well guide you through the device pairing process on Windows, one step at a time. Bluetooth Low End Extension. 1. After further development with partners in particular Logitech and within EUFP6 project MIMOSA,1. STMicroelectronics since its early stage,1. October 2. 00. 6 with the brand name Wibree. 1. After negotiations with Bluetooth SIG members, an agreement was reached in June 2. Wibree in future Bluetooth specification as a Bluetooth ultra low power technology, now known as Bluetooth Smart technology. 1. Integration of Bluetooth Smart with version 4. Core Specification was completed in early 2. The first smartphone to implement the 4. Phone 4. S, released in October 2. A number of other manufacturers released Bluetooth Smart Ready devices in 2. ApplicationseditBorrowing from the original Bluetooth specification, the Bluetooth SIG defines several profiles specifications for how a device works in a particular application for low energy devices. Manufacturers are expected to implement the appropriate specifications for their device in order to ensure compatibility. A device may contain implementations of multiple profiles. All current low energy application profiles are based on the generic attribute profile GATT, a general specification for sending and receiving short pieces of data known as attributes over a low energy link. 2. Bluetooth 4. 0 provides low power consumption with higher bit rates. In 2. 01. 4, Cambridge Silicon Radio now part of Qualcomm launched CSR Mesh. CSR Mesh protocol uses Bluetooth Smart to communicate with other Bluetooth Smart devices in the network. Each device can pass the information forward to other Bluetooth Smart devices creating a mesh effect. For example, switching off an entire building of lights from a single smartphone. 5clarification needed The Bluetooth SIG recently formed the Smart Mesh study group to research and define its use cases in an effort to define a standard specification. 2. Health care profileseditThere are many profiles for Bluetooth Smart devices in healthcare applications. The Continua Health Alliance consortium promotes these in cooperation with the Bluetooth SIG. BLP Blood Pressure Profile for blood pressure measurement. HTP Health Thermometer Profile for medical temperature measurement devices. GLP Glucose Profile for blood glucose monitors. CGMP Continuous Glucose Monitor ProfileSports and fitness profileseditProfiles for sporting and fitness accessories include BCS Body Composition ServiceCSCP Cycling Speed and Cadence Profile for sensors attached to a bicycle or exercise bike to measure cadence and wheel speed. CPP Cycling Power ProfileHRP Heart Rate Profile for devices which measure heart rate. LNP Location and Navigation ProfileRSCP Running Speed and Cadence ProfileWSP Weight Scale ProfileInternet ConnectivityeditIPSP Internet Protocol Support ProfileGeneric SensorseditESP Environmental Sensing ProfileUDS User Data ServiceHID ConnectivityeditHOGP HID over GATT Profile allowing Bluetooth LE enabled Wireless mice, keyboards and other devices offering long lasting battery life. Proximity sensingeditElectronic leash applications are well suited to the long battery life possible for always on devices. 2. Manufacturers of i. Beacon devices implement the appropriate specifications for their device to make use of proximity sensing capabilities supported by Apple Inc. Devices. 2. 6Relevant application profiles include FMP the find me profile allows one device to issue an alert on a second misplaced device. 2. PXP the proximity profile allows a proximity monitor to detect whether a proximity reporter is within a close range. Physical proximity can be estimated using the radio receivers RSSI value, although this does not have absolute calibration of distances. Typically, an alarm may be sounded when the distance between the devices exceeds a set threshold. Alerts and time profileseditThe phone alert status profile and alert notification profile allow a client device to receive notifications such as incoming call alerts from another device. The time profile allows current time and time zone information on a client device to be set from a server device, such as between a wristwatch and a mobile phones network time. BatteryeditThe Battery Service exposes the Battery State and Battery Level of a single battery or set of batteries in a device. ImplementationeditStarting in late 2. Bluetooth Smart integrated circuit implementations were announced by a number of manufacturers. Implementations commonly use software radio so updates to the specification can be accommodated through a firmware upgrade. HardwareeditCurrent mobile devices are commonly released with hardware and software support for both Classic Bluetooth and the Bluetooth Smart standard.
