White Paper

With yearly shipments of more than 10 billion microcontrollers that all can exchange information locally or through the Internet, a huge variety of so called “intelligent devices” are enabled. All these devices can be accessed over the Internet and this evolution is commonly referred to as Internet of Things (IoT). IoT typically requires a local low power wireless connection along with the Internet connection.

For most such applications and solutions, a gateway is required to connect sensor nodes to the Internet via a local infrastructure or using a cellular connection. Gateways are important components of the IoT vision. These gateways can be used to connect Bluetooth low energy devices to the Internet and can also be used as "repeaters" to extend the system range.

This whitepaper describes how Bluetooth low energy technology works and how it can be used to connect devices to Internet-based services and applications. A significant feature in Bluetooth low energy compared to other IoT wireless technologies is the support for smartphones and tablets. The whitepaper thus also describes how a smartphone or tablet can be used in IoT.
