What are you going to do when you get an unprecedented response from your new Kickstarter project? You throw in some extra features to keep your new fans happy. Allerta, the same company behind the InPulse smartwatch, has announced that its new Pebble smartwatch will now arrive with low-power Bluetooth 4.0 compatibility. The watches will still interact with Bluetooth 2.1, but inclusion of the latest version should ensure a better degree of future-proofing, with a view to hooking up with wireless heart monitors in the near future. The new feature will be built into the watches ahead of its release and enabled with a later software update. Better still, the makers promise that these Bluetooth plans have been in the pipeline for a while and shouldn't affect the watch's launch date.
