In addition, the latest BLE-Stack includes support for fourteen profiles with associated sample applications for fast development of Bluetooth low energy-compliant sensor devices. TI’s BLE-Stack 1.2 is available royalty-free to all using TI’s CC254x Bluetooth low energy system-on-chip (SoC) solutions.
Developed to better serve the growing Bluetooth low energy wearables market, TI’s BLE-Stack 1.2 has an advanced master-slave switch feature, increased stack configurability, and further power optimisation, which enable the design of low-power, single-chip-based products with Bluetooth Smart capabilities. The TI BLE-Stack’s 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.
TI’s Bluetooth low energy devices for sensor applications are one-chip integrated solutions. Combined with TI’s protocol stack, profile software and sample applications, the CC254x SoC family forms a flexible and cost-effective single-mode Bluetooth low energy solution. To simplify design and speed time to market of Bluetooth low energy applications, TI’s solutions come with an extensive selection of development tools, technical documentation, reference designs and application expertise.
“By enabling devices that can switch between master and slave mode modes, TI is driving the growth of wearable and sensor-based devices to take advantage of the increasing number of smartphones and tablets with Bluetooth low energy,” said Sid Shaw, product marketing manager, Wireless Connectivity, TI. “For end users this translates into a smooth Bluetooth user experience – ease of use, long battery life and small-sized portable devices.”
