FOTA:
firmware over-the-air

The harsh reality of smart deployments makes it really hard to keep up with the challenges that lie ahead, especially in terms of increasingly popular resource-constrained battery-powered sensors and actuators. The first thing to consider when picking a FOTA solution is its ability to adapt and scale to accommodate the specific needs of the project. Here, much depends on the protocol used throughout the deployment. Among the standards used in IoT, the lightweight machine-to-machine protocol seems to be the leading solution in the field of firmware over-the-air upgrades. By providing a well-defined model for performing over-the-air upgrades, the protocol allows you to:

As one of the early adopters of this comprehensive standard, AVSystem’s Coiote IoT Device Management platform benefits from all the features that it offers. It gives its users freedom and flexibility in planning upgrade campaigns by ensuring that only eligible devices are involved in the upgrade, effectively reducing network traffic and power drain. By dint of using the blockwise file transfer, the platform divides firmware image into parts and, in case of unexpected connection or power disruption, resumes the firmware over-the-air upgrade process as soon as the circumstances are more favourable. Also, the platform provides top-class file transfer security by leveraging the DTLS standard to avoid data transport layer vulnerabilities.
