In 2009, Bluetooth 3.0 introduced Wi-Fi connection capability, allowing faster data transmission. Version 2.1, released in 2007, provided more data transmission security, further reduction in power consumption and an improved pairing system which did not require any PIN. It notes how version 2 abolishes radio frequency interference using frequency hopping, and provides security against snooping and tracking.īluetooth 2.0 also improved on 1.2 with both higher connection speed and lower power consumption. Bluetooth evolutionīluetooth has evolved through 1.0, 1.2, 2.0, 2.1, 3.0, 4.0, 4.1 and 4.2, and is currently at 5.Ī document, Bluetooth Report, describes how the Bluetooth Special Interest Group (SIG) has managed the evolution of these steps. Of these two standards, LE is particularly important to manufacturers and integrators wishing to build and use Bluetooth-enabled IoT sensors, because of its low-energy capabilities – a critical requirement for sensor nodes relying on battery power and/or energy harvesting. Bluetooth LE Mesh creates large-scale device networks tailor-made for building automation, sensor network, asset tracking and any solution where multiple devices need to reliably and securely communicate with one another. Mesh is a network topology for many-to-many (m:m) device communications. It optimises localised information sharing, making it ideal for beacon solutions such as point-of-interest (PoI) information and item- and way-finding services. Broadcast is a network topology that establishes one-to-many (1:m) device communications. It is ideal for data transfers and well suited for connected device products such as fitness trackers and health monitors. P2P is used to create one-to-one (1:1) device communications. BR/EDR audio streaming is widely used in wireless speakers, headsets and hands-free in-car systems.īluetooth Low Energy (LE) enables short-burst wireless connections and uses multiple network topologies, including point-to-point (P2P), broadcast and mesh. Current Bluetooth hierarchyĪfter development through many revisions, Bluetooth has evolved into two flavours - Basic Rate/Enhanced Data Rate (BR/EDR) and Low Energy (LE).īluetooth BR/EDR allows continuous wireless connection and uses a point to point (P2P) network topology in establishing one-to-one (1:1) device communications. Bluetooth’s two flavours are Basic Rate/Enhanced Data Rate (BR/EDR) and Low Energy (LE). It is a low-power wireless connectivity technology used to stream audio, transfer data and broadcast information between devices.

He was later quoted as saying “King Harald Bluetooth…was famous for uniting Scandinavia just as we intended to unite the PC and cellular industries with a short-range wireless link.”Īs we now know, the temporary name became permanent, with Bluetooth and its variants becoming synonymous with short-range wireless technology today integrated into more than 8.2 billion products produced by over 30,000 Bluetooth SIG members.

During the meeting, Jim Kardash from Intel suggested Bluetooth as a temporary code name. Fast-forward to 1996, when three industry leaders – Intel, Ericsson and Nokia – met to plan standardisation of a new short-range radio technology. It also provides relative humidity measurements as a digital output accurate to a maximum +/-3.5%.Over a millennium ago, King Harald Gormsson was famous for two things uniting Denmark and Norway in 958, and for his dead tooth, which was a dark grey-blue in colour. The ENS210 provides output in Kelvin, accurate to a maximum +/-0.2 degree C over the range of 0 to 70 degree C. The reason I mention it is that an Evaluation Kit, for the ENS210, is available (pictured below). If you are interested in this area, note that ams, the sensor and analogue IC specialist, launching a pre-calibrated relative humidity and ambient temperature sensor IC at Electronica recently.

Basically, fire up the Arduino IDE, download the Blynk library, get an “Auth Token” for using the Blynk app, edit and upload the sketch, and then connect the 101 with Blynk via the apps Bluetooth button.
