LightweightM2M (LwM2M) by OMA SpecWorks is a device management protocol designed for sensor networks and the demands of a machine-to-machine (M2M) environment. It is designed for the remote management of devices and is based on the Contrained Application Protocol (CoAP, RFC 7252), which itself provides an interaction model similar to the client/server model of HTTP.
The Zephyr RTOS from the Linux Foundation possesses built-in support for LwM2M. In this presentation, you will discover how to leverage LwM2M to manage Zephyr-based devices.
Zephyr devices can be connected in two possible (direct and in-direct) ways to the internet. Directly using Modem/WiFi/Ethernet medium or in-directly via local radio through Gateways like Linux. Upgrading such Zephyr system in the field is a complex task and must be robust, secure.
This talk will details various possible update solutions available like UpdateHub, Hawkbit, SWUpdate for Zephyr. Using a NXP FRDM-K64F board as an example, we will discuss and demo different possible ways for updating Zephyr system.
