LWM2M for device management at scale

LWM2M — The Standard

OMA Lightweight M2M (LWM2M) is the open standard protocol for cellular IoT device management. Defined by the Open Mobile Alliance (since version 1.0 in 2017, with 1.2 published in 2020). LWM2M provides: device registration with a management server; standardized object/resource model for device data; remote management operations (read device info, write configuration, execute commands); firmware update (FOTA) via a standard object model; observation/notification of resource changes. Transport: typically CoAP over UDP with DTLS security (or OSCORE+EDHOC for ultra-constrained). LWM2M is the most…
