Connectivity is all about solving the main problem - establishing a method to communicate. The strategies used are affected by the constraints on the network devices. Power availability often is the most significant one.
The following protocols are specifically designed to address low power constraints. They are usually associated with lower complexity and bit transfer rates in the supported IoT devices.
Named after a tenth-century Danish king who unified several fractious tribes, Bluetooth is a familiar technology to most consumers. The specification is maintained by an organization called the Bluetooth Special Interest Group (SIG) made up of 25,000 companies. Bluetooth Low Energy (BLE) is a newer implementation that is not directly compatible with Bluetooth classic (of mobile phone headset fame). It was designed for low power needs and a less...
