Anjay LwM2M SDK features

Implement support for OMA Lightweight M2M on your devices.

  • Many tools in one package

    Tools such as LwM2M/CoAP REPL for testing and packet inspection, a sample client demonstrating library usage or a client for rapid prototyping using Python/Bash scripts come in one SDK!

  • Working on any platform

    Anjay can be compiled out of the box on Linux, FreeRTOS (including Amazon FreeRTOS), Mbed OS, Thread‐X, Android, Windows, and other POSIX-operating systems as well as non-POSIX systems (implementation of OS abstraction layer required).

  • Compatible with various hardware stacks

    Anjay LwM2M SDK is compatible with many hardware platforms, including: ARM, X86, MIPS or PowerPC.

  • Conformance to the latest LwM2M version

    With the commercial version of Anjay you can get support for LwM2M 1.1.1 features on top of all core interfaces specified in LwM2M 1.0.2 which allows effortless interoperability with most LwM2M servers on the market.
