Bluetooth

Bluetooth

Bluetooth Low Energy was originally aimed at wearable technology, not the broad IoT market. But in early 2014, CSR, a semiconductor maker, announced a mesh network for Bluetooth, meaning it could now connect to thousands of things.

Bluetooth's ubiquity in mobile devices means that a Bluetooth mesh network as a broad IoT platform will have some advantages. Because Bluetooth is already a feature on smartphones, a smartphone could act as a management hub inside a home. But it's not perfect. A hub will be needed if someone wants to connect with the home network remotely, such as from work.
