Thingsquare and STMicroelectronics have teamed up to bring Thingsquare Mist Internet-connectivity software to ST's SPIRIT1 radio transceiver on the STM32L MCU platform. According to the firms, Thingsquare Mist is a game-changing software system that offers true Internet-connectivity to the Internet of Things.

Used in connected-home products, smart lighting systems and smart city projects, Thingsquare Mist builds on well-known open-source components, has a small memory footprint, low computational requirements, is battle-proven and works with multiple MCUs with a range of radios.

ST's SPIRIT1 is a very low-power RF transceiver, intended for RF wireless sensor node applications in the sub-1GHz band such as automatic meter infrastructure, alarm and security systems, home and building automation, and industrial monitoring and control. The SPIRIT1 uses a very small number of discrete external components, integrates an embedded 'listen-before-talk' (CSMA/CA) engine and an AES 128bit encryption co-processor for secure data transfer.

The SPIRIT1 transceiver works in tandem with ST's ARM Cortex-M3-based STM32 L1 MCU series, which boasts ultra-low-power consumption with no compromise on performance. The MCU adds a wide range of integrated peripherals such as USB, analogue-to-digital converter and LCD controller that make it suitable for industrial, consumer, fitness and healthcare applications, the firms added.

The SPIRIT1 support is integrated in the first release of Thingsquare Mist. The SPIRIT1 transceiver is available from ST.
