[box_dark]Bluetooth Low Energy Profiles[/box_dark]

The Bluetooth profile defines the specific usage of the base technology to support targeted applications, ensuring interoperability between products developed by different manufacturers.
There are following profiles as follows:

  • Application Profiles:

The commonly available specification of Bluetooth low energy application profiles has to be expected prior to commonly available appliances.Applications will be certainly enhanced by the availability of coin-cell battery powered wireless products and sensors that use BLE technology:

  • Consumer profiles

The first simple consumer profiles will benefit from the availability of BLE are, for example, home entertainment devices such as media center remotes and RF remote controls, which will become a necessity for new generations of internet-connected televisions and which could replace the current infrared remote controls.

  • Health care and Fitness profiles

Health care and fitness profile is main focusing profile in Bluetooth low energy. The intrinsic security, high reliability, low power and simplicity of BLE are a perfect fit for these types of devices.

  • Sporting profiles

Sports with Bluetooth low energy technology is locating as well as vital monitoring.
