The system is based on the company’s RSL15 MCU, a low power Bluetooth 5.2 MCU, and which incorporates software algorithms and components provided by Unikie and CoreHW, delivering a fully integrated solution with components that have been optimised to work together.
The new Bluetooth Low Energy (LE) solution enables tags to be used for tracking objects or persons with sub-metre accuracy in defined closed spaces such as warehouses, stores or other buildings. It is scalable to large volumes of tracked objects in terms of performance and cost while reducing the amount of development effort and time-to-market.
With several new advanced features, the RSL15 is intended for various industrial automation applications, including asset tracking, smart retail and IoT edge nodes.
Accuracy: The RSL15 Bluetooth 5.2 MCU supports longer range, higher data transmissions and localisation through Angle of Arrival (AoA) and Angle of Departure (AoD).
Power Efficiency: Its smart sensing feature allows the Arm Cortex-M33 processor to remain in deep sleep while continuing to monitor sensor interfaces.
Security: The RSL15 is designed with Arm TrustZone and Arm CryptoCell-312 technology to establish a device’s root of trust and to protect code and data authenticity, integrity and confidentiality. PSA Level 1 certified, this design enhances the security measures already offered in the Bluetooth protocol for assurance at both the data and application levels.
Unikie is an engineering company focused on enabling smart spaces and developed the software algorithms and components to calculate the real-time positions of a Bluetooth LE-based tag, using the IQ values for the received signals. The company’s high-performance localisation software is packaged as the Unikie BLE Localization Engine product for edge or cloud deployment. In addition, Unikie’s APIs can be integrated into enterprise systems and data analysers.
CoreHW, a fabless semiconductor company developing Integrated Circuit (IC) technologies, provides Bluetooth Angle of Arrival (AoA) development kits to a range of industries, enabling them to leverage indoor location systems for enhanced location-based applications. CoreHW designs and supplies Bluetooth LE enabled antenna array boards in various form factors that offer highly accurate location capabilities at a 10-centimetre level.
