Bluetooth Low Energy and the Internet of things is believed to be the perfect matchmaking. Even though Bluetooth doesn’t necessary gives devices the ability to connect to the Internet they still have so much capacity. The Bluetooth Low Energy enabled solutions will increase the functionality of IoT Systems, by creating a reliable framework and efficient connectivity for the devices. Devices can use BLE to connect to each other thereby improving reliability, increasing range, mitigate security risk, reduce cost, and most importantly improve battery life.
The launch of the Bluetooth 5, which promise so much more are beginning to see some adoption in the open hardware industry, and a good example is the Particle Xenon using the Nordic nRF52840 SOC. The Nordic nRF52840 SoC is designed around an ARM Cortex-M4 CPU and comes with a 1 MB flash with cache and a 256kB of RAM.
