Wearable devices are made possible with next-gen Bluetooth low energy application software

Texas Instruments has launched the company’s latest Bluetooth low energy application software, the BLE-Stack 1.2, based on the Bluetooth v4.0 release.

The BLE-Stack 1.2 is designed to further drive Bluetooth Smart and Smart Ready devices such as wearables - a market experiencing large growth as manufacturers take advantage of the increased numbers of Bluetooth v4.0-enabled smartphones and tablets. Additionally, the latest BLE-Stack includes support for fourteen profiles with associated sample applications for fast development of Bluetooth low energy-compliant sensor devices. TIs BLE-Stack 1.2 is available royalty-free to all using TIs CC254x Bluetooth low energy system-on-chip (SoC) solutions.
To better serve the growing Bluetooth low energy wearables market, TIs BLE-Stack 1.2 has an advanced master-slave switch feature, increased stack configurability, and further power optimization, which enable the design of low-power, single-chip-based products with Bluetooth Smart capabilities. The TI BLE-Stacks new master-slave feature enables a CC254x SoC to support both master and slave modes at different times by allowing an application to easily switch between the two modes. For example, a Bluetooth Smart sports watch (peripheral) built with a CC254x can be connected to a Bluetooth Smart Ready smartphone (central device). The same sports watch can then switch to central device mode to obtain data from other peripheral devices, such as a heart rate monitor and a blood pressure sensor.
