Like all other Bluetooth iterations, Bluetooth 4.1 will also be fully backwards compatible with earlier versions, but you will need communication between 4.1 devices to see its benefits. Consequently devices you already own may be about to get a lot smarter. The changes can be made (at the manufacturer’s discretion) through patches applied over the air. A scenario would be an LTE capable phone that operates without any interference while using a Bluetooth connection, automatically saves power disconnecting and reconnecting to Bluetooth peripherals as necessary and is not needed for these peripherals to communicate together before they send their aggregated data back to the handset on demand.Ĭrucially, Bluetooth 4.1 is an upgradeable path for all existing Bluetooth 4.0 devices as well. The combination of these three elements potentially transforms the devices developers can build. What does Bluetooth 4.1 mean for developers? This is crucial to the Internet of Things concept: peripherals become independent and can build their own networks before bringing the collation of all their data to you. This is hugely significant because it allows the host device to be cut out of the equation and for peripherals to communicate independently.įor example, whereas previously a smartwatch would need to talk to your phone to get data from a heart monitor, now the smartwatch and heart monitor can talk directly saving your phone’s battery and then upload their compiled results directly to your phone. In short: devices are no longer all treated the same and the randomness of Bluetooth connections / disconnections and the power drain this causes should reduce dramatically.īluetooth 4.1 devices can act as both hub and end point simultaneously. This means devices can better manage their power and that of the device they are paired to by automatically powering up and down based on a bespoke power plan. Rather than carry a fixed timeout period, Bluetooth 4.1 will allow manufacturers to specify the reconnection timeout intervals for their devices. Given most phones will come with 4G next year this is a vital improvement. Bluetooth 4.1 eliminates this by coordinating its radio with 4G automatically so there is no overlap and both can perform at their maximum potential. There are three major improvements at the heart of the Bluetooth 4.1 specification:īluetooth and 4G (LTE) famously don’t get on: their signals interfere degrading one another’s performance and draining battery life. Bluetooth 4.1 vs Bluetooth 4.0: What is new? This includes smartwatches, a continuing topic of interest among manufacturers and tech enthusiasts. The job of Bluetooth 4.1 is to drive the ‘Internet of Things’ (Io, namely the thousands of smart, web connected devices – from fridges to toothbrushes – that are expected to enter our lives over the next decade. A point iteration sounds uninteresting, but it is the first significant update since Bluetooth 4.0 was introduced back in 2010 and comes with a great weight of expectation. Last week the Bluetooth Special Interest Group (SIG) announced the adoption of updates to the Bluetooth 4.0 standard that shift it to version 4.1.
