The latest specification also provides manufacturers with more control over creating and maintaining Bluetooth connections by making the reconnection time interval flexible and variable. This allows devices to reconnect automatically when they are in proximity of one another. The consumer can leave the room and upon returning, two recently used devices reconnect without user intervention.
Bluetooth Smart technology provides bulk data transfer. For example, through this new capability, sensors, which gathered data during a run, bike ride or swim, transfer that data more efficiently when the consumer returns home.
Bluetooth 4.1 also extends the Bluetooth Smart development environment by providing product and application developers with even more flexibility to create products that can take on multiple roles. With this new capability, a single device acts as both a Bluetooth Smart peripheral and a Bluetooth Smart Ready hub at the same time. For example, a smart watch acts as a hub gathering information from a Bluetooth Smart heart rate monitor while simultaneously acting as a peripheral to a smartphone - displaying new message notifications from the phone. As the Bluetooth Smart ecosystem grows, the Bluetooth SIG expects more solutions to play both a hub and peripheral role.
By adding a standard means to create a dedicated channel, which could be used for IPv6 communications in the Core Specification, the groundwork is laid for future protocols providing IP connectivity. These updates make it possible for Bluetooth Smart sensors to also use IPv6, giving developers and OEMs the flexibility they need to ensure connectivity and compatibility.
