IoT Bluetooth Chips – Technology, Design and Module Selection Considerations

Bluetooth is a global wireless technology for simple, secure and point-to-point connectivity based on IEEE 802.15.1 standard. Created as an open standard to allow connectivity and collaboration between disparate products and industries, Bluetooth is building personal area networks (PANs). The technology is introducing new possibilities for devices and certainly modifying the consumer behaviour. Bluetooth chips enable devices to communicate via a standard radio frequency instead of through cables, wires or direct user action. The data can be exchanged over short distances using short-wavelength UHF radio waves in the ISM band (Industrial, Scientific, and Medical radio band ) from 2.4 to 2.485 GHz from fixed and mobile devices. Bluetooth has expanded to short-range networking, although designed to replace short-range cable protocols. Bluetooth is enabling a global vision to connect devices ranging from mobiles to automobiles, medical equipments to manufacturing plants, wearables to consumer electronics, and fulfillment centers. Bluetooth SIG (Special Interest Group): The working group creates the Bluetooth Core Specification and services. They ensure the specification and layers of services work at the highest interoperability standards. Bluetooth devices requires FCC and Bluetooth SIG certification. Bluetooth compliance versions are SIG 1.0, SIG 1.0b, SIG 1.1, SIG...
