The Bluetooth Special Interest Group has announced the newest version of the Bluetooth specification, Bluetooth 4.1. Bluetooth 4.1 promises new features that will allow the spec to “work seamlessly” with LTE.
Better connections will allow manufacturers to control the reconnection time interval — devices can reconnect automatically when in proximity to each other, and disconnect when apart, allowing for improved battery life and a better user experience. Bulk data transfer will allow for a more efficient transfer of data gathered away from one’s home computer — the example given by the Bluetooth SIG notes an efficient transfer of exercise data.
A Bluetooth device can also now act as both a peripheral and a hub at the same time, allowing for greater interaction between devices. Most interestingly, Bluetooth 4.1 is an over-the-air update that won’t require the purchase of new devices — the Bluetooth SIG recommends that manufacturers “immediately” implement Bluetooth 4.1 in their devices.
