Texas Instrument's most updated Bluetooth® low energy BLE-Stack™ 1.4.0 software stack for TI’s CC2540 and CC2541 devices includes all necessary software to get started on the development of single-mode Bluetooth low energy applications. With new software features, the BLE-Stack 1.4.0, is available royalty-free to customers using TI’s C2540/41 Bluetooth low energy system-on-chip (SoC) family and also runs on TI’s SensorTag and remote control (CC2541DK-RC) development kits.
New software features on BLE-Stack 1.4.0 include:
- Overlapped Processing – This allows the stack to concurrently process while the radio is active. Since the stack is concurrently processing, it is able to insert new data in the Tx buffer during the connection event, causing additional packets to be sent before the end of the event and thus improving system throughput.
- Improved Over-the-Air Firmware Download (OAD) – Faster verification of firmware images after OAD is complete. This, combined with the overlapped processing to improve throughput,
- Improved SPI and UART drivers – Improved robustness of the HAL (Hardware Abstraction Layer) drivers for using the UART and SPI interface, in particular when used with power management and/or used in network processor mode.
BLE-stack 1.4.0 includes object code with the latest Bluetooth low energy protocol stack supporting multiple connections, sample projects and applications covering an extensive set of profiles with source code, and BTool, a Windows PC application for testing applications. In addition to the software, the kit contains documentation, including a developer’s guide, sample applications guide, and API guide.
The SmartRF Packet Sniffer is a free and easy to use tool for analyzing the packets sent over a Bluetooth low energy link. Use the CC2540 USB dongle or a SmartRF05EB + CC2540EM (included in the CC2540DK) to capture the packets. The tool isa available here.
Texas Instruments also works with Perytons to provide an advanced protocol analyzer for Bluetooth low energy. The Perytons BLE Protocol Analyzer (Peryton-Smart) supports the TI’s CC2540 USB Dongle which can be ordered as the CC2540EMK-USB kit. Perytons provides protocol analyzers with several views, features and add-ons, providing detailed analysis of Bluetooth low energy sessions. You can also use the Perytons BLE Protocol Analyzer to look at your TI SmartRF Packet Sniffer BLE capture files (.psd) with this online converter.
