Nordic Semiconductor’s nRF52840 multiprotocol Bluetooth Low Energy (Bluetooth LE) System-on-Chip (SoC) has now become one of the first devices to support Bluetooth LE with Amazon FreeRTOS.
Amazon FreeRTOS is an operating system for microcontrollers that make small, low-power edge devices easy to program, deploy, secure, connect, and manage. It is based on the FreeRTOS kernel, a popular open source operating system for microcontrollers, and extends it with software libraries that make it easy to securely connect your small, low-power devices to AWS cloud services like AWS Internet of Things (IoT) Core or to more powerful edge devices running AWS IoT Greengrass.
The Nordic nRF52840 SoC has become one of the world’s most popular Bluetooth LE chips since its introduction in 2016. Featuring an Arm Cortex-M4F processor, 1MB of Flash and 256kB of RAM memory, together with a multiprotocol radio that supports IEEE 802.15.4 in addition to complete Bluetooth 5 support, the nRF52840 is the ideal platform for IoT devices. As many customers’ de-facto, ultra-low power IoT connectivity chip of choice, offering a wide breadth of connectivity options with outstanding energy efficiency, the nRF52840 is an excellent complement to, and expands, the solution and product application range possible with Amazon FreeRTOS.
The Bluetooth LE support in Amazon FreeRTOS was recently announced at AWS re:Invent 2018 in Las Vegas. This Beta release includes a GATT/GAP API, a custom profile for provisioning Wi-Fi credentials over Bluetooth LE, and companion iOS and Android SDKs. Also included is a custom profile for MQTT over Bluetooth LE that offers seamless Device-to-Cloud messaging via an iOS or Android proxy device.
