Texas Instruments Inc. (TI) has unleashed 10 Bluetooth low energy technology (Bluetooth v4.0) profiles with corresponding sample applications to push the market development of Bluetooth low energy-compliant sensor devices.

The Bluetooth low energy application software is part of TI's BLE-Stack, and is available royalty-free to all using TI's CC2540 Bluetooth low energy system-on-chip (SoC).

TI has achieved Bluetooth Special Interest Group (SIG) certification for find-me, health thermometer, heart rate and proximity profiles. The updated BLE-Stack also includes support for to-be-adopted profiles such as blood pressure sensor, remote control (soft command), watch (time/network availability), emulated keyboard/dongle (HID), and time and alert notification profiles. It also adds support for Bluetooth low energy central and peripheral configurations. When set to the central configuration, the CC2540 SoC can support up to three simultaneous connections. For example, an end user can run a heart rate monitor, blood pressure sensor and health thermometerall connected to one central health device.

In addition to interoperability testing, the BLE-Stack has undergone testing against TI's dual-mode Bluetooth solutions. TI provides single-mode Bluetooth low energy solutions for sensor applications and dual-mode solutions for mobile handheld devices, including the BlueLink 7.0 (BL6450), WiLink 6.0 (WL127x) and WiLink 7.0 (WL128x) offerings. With both sides of the link, the company claims to deliver a fully tested, robust Bluetooth low energy ecosystem.

The BLE 1.1 Bluetooth low energy software stack is from TI, royalty-free to all using the CC2540 Bluetooth low energy SoC. The CC2540DK-MINI development kit is available in TI's e-store for $99, and the enhanced CC2540DK development kit will be available in mid-September for $299.
