Significant upgrades to Bluetooth low energy introduced through versions 4.1, 4.2 and 5 were designed to make the short-range wireless standard a better choice for Internet of things (IoT) wireless applications. Part 1 of this two-part series describes those upgrades and outlines their advantages. Part 2, here, introduces Bluetooth low energy SoCs, modules and kits, and discusses their relative tradeoffs as a design approach. By the end of the series, a competent designer should be comfortable starting a Bluetooth low energy design. http://bit.ly/2plKmnI
