Silicon Labs unveiled a dual-mode Bluetooth Smart Ready module solution that gives embedded developers the flexibility to integrate both Bluetooth Smart and Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) wireless technologies.
The BT121 module, part of the recently acquired Bluegiga product range, provides a pre-certified, fully integrated solution that includes the Bluetooth radio, microcontroller (MCU) and onboard Bluetooth software stack, supported by Silicon Labs’ complimentary Bluetooth Smart Ready software development kit (SDK) and easy-to-use BGScript scripting language.
Both module and software are designed to help developers accelerate time to market and reduce development costs and compliance risks by providing a versatile, plug-and-play Bluetooth solution. The BT121 is ideal for applications requiring connectivity to legacy devices that only support Bluetooth BR/EDR, as well as the latest applications using Bluetooth Smart such as connected home, health and fitness, wearables and point-of-sale terminals.
The module can connect to legacy devices that only support Bluetooth SPP or Apple iAP2 profiles, for example, as well as to devices that support Bluetooth Smart. It integrates a high-performance radio with an extended range of up to 400 metres, a low-power ARM MCU and a fully certified Bluetooth Smart Ready protocol stack in a compact 11 x 14 mm surface-mount package.
No RF or Bluetooth protocol development expertise is necessary to implement the BT121 in Bluetooth designs. The module can be used as a peripheral along with an external host MCU, or applications can be embedded into the built-in MCU with the Bluegiga BGScript scripting language, creating a completely standalone design with minimal external components.
Available for download at no charge from Bluegiga (www.bluegiga.com), the Bluetooth Smart Ready SDK is a set of software tools for simplifying the development of Bluetooth Smart Ready applications. Developers can access dozens of example Bluetooth Smart application profiles, which can be used as templates.
The Bluetooth Smart Ready stack and SDK are fully compatible with Silicon Labs’ recently announced Blue Gecko Bluetooth Smart modules. This compatibility makes it easy for developers to migrate their designs between Silicon Labs’ Bluetooth Smart and Smart Ready modules with a consistent set of application programming interfaces (APIs) and software tools.
