AWS IoT Core for LoRaWAN is a fully managed LoRaWAN Network Server (LNS) of AWS IoT Core that lets wireless devices that use low-power long-range wide area network (LoRaWAN) technology connect to the AWS cloud. Now, AWS IoT Core for LoRaWAN supports Firmware Over-the-Air Update (FUOTA) that allows customers to deliver secure and reliable firmware updates to the devices in the field using LoRaWAN multicast and fragmentation mechanisms defined by the LoRa Alliance. These mechanisms aim to minimize the device’s battery consumption and handle large file transfers (few hundred KBs).

Customers can provide a firmware image, set up a multicast group with a target list of devices, and initiate a FUOTA task for the group of devices. With the FUOTA feature, AWS IoT Core for LoRaWAN customers can enable devices deployed in the field to be remotely updated for bug fixes, patching security vulnerabilities, and supporting new features. It eliminates the need to replace devices or perform software updates by visiting the sites in person thus reducing the maintenance and operational costs. This will also allow customers to focus on building applications, rather than doing undifferentiated heavy lifting of developing and maintaining their own device management solution.

The FUOTA feature is supported in all AWS Regions where AWS IoT Core for LoRaWAN is available. To learn more about FUOTA, please see AWS IoT for LoRaWAN product page.
