Archos turns to Bluetooth Low Energy to monitor activities in the home |
February 25, 2014
French tablet maker Archos is using a tweaked version of Bluetooth Low Energy to monitor and control smart devices around the home.The range of products shown at Mobile World Congress, including cameras, weather stations, movement detectors, door and window sensors and power switches, will go on sale in April.Bluetooth LE is better suited for home monitoring than earlier versions of Bluetooth because devices remain in sleep mode most of the time, only waking up when contacted. Using Bluetooth LE, sensors can run on lithium button cells for up to two years, Archos marketing director Bénédicte Ernoult said at the show.Nevertheless, it does have some shortcomings: Its range is insufficient to cover a typical house and a Bluetooth LE host can typically only maintain communications with three or four other devices, she said. To solve those problems, the Android tablet at the hub of the Archos smart-home system has a special antenna taking the range to 20 meters and a tweaked software stack allowing it to communicate with up to 32 devices simultaneously.To read this article in full or to leave a comment, please click here
