Anjay
OPEN SOURCE
LwM2M library to make IoT devices market-ready
Anjay is a library that helps vendors of Internet of Things equipment to implement support for OMA LwM2M – a lightweight management and monitoring protocol.
How does it work?
-
Try our open-source code
Use the quick start guide to run a sample client and analyze all the mandatory protocol elements.
-
Integrate Anjay with your device
Easily implement a complete LwM2M client using full documentation and usage examples.
-
Check our commercial options
Get access to extended support, the test server and full SIM card support as part of the commercial license.
Features
Conformance to latest LwM2M specification
Anjay implements all core interfaces specified in the latest revision of the OMA document, which allows effortless interoperability with most LwM2M servers on the market right from the first boot.
Support for any data model
The library is data model agnostic and can be used with any of the standard LwM2M Objects and Resources published by OMA, as well as with any custom data model extensions.
Runs on any platform
Anjay can be compiled for any platform with a standard ISO C compiler. Operating system abstraction layer allows to easily port it, while it works on POSIX- compliant systems out of the box.
Latest web standards built-in
Anjay uses its own internal implementation of CoAP, LwM2M's underlying protocol ‒ optimized for size and supporting all the latest standards, including Observe and Block extensions.
Anjay implements the core LwM2M protocol and some essential parts of the data model. However, in general, implementation of the concrete data model has to be done by the customer.

Minimal external dependencies
The only external library necessary is an implementation of DTLS ‒ Anjay can be otherwise used even on “bare metal”. See →Technical specification for details.
Benefits
Make your IoT devices market ready
Use Anjay to implement OMA Lightweight Machine-to-Machine (OMA LwM2M), an open standard protocol to face new challenges that arise in the field of management and monitoring.
Try as open source with no commitment
Anjay’s core technology is available as a →free and open source project. You are free to use it as you like, but also be sure to check out our →commercial option!
Save your time and effort
Focus on the essentials and instead of implementing complicated internal logic of the management protocol ‒ let Anjay do the job. Concentrate only on features specific to your product.
Avoid
incompatibility
Take advantage of the open nature of the protocol to market your products among different customers. As a member of the Open Mobile Alliance, we have taken as much care as possible to make Anjay interoperable with many different LwM2M servers available on the market.
Open source
Anjay is a free and open source software available under Apache 2.0 license. Start building your LwM2M client right away with help of multiple code samples, extensive documentation and easy to use API. Later on, if you decide that you need dedicated support or enterprise grade warranty make sure to check out our →commercial option.
Commercial option
Enterprise-level support
In case you encounter any problems during integration, you can ask us directly – our skilled and experienced engineers are ready to help you. They can even help you on-site for rapid training and development.
Simplified testing
Access a dedicated installation of our LwM2M server (→Coiote) to test your management interface in the same way that your customers will. Additionally, you will get additional testing and debugging tools to speed up your development process, not included in the open source package.
Device certification program
Our quality assurance team is ready to check that your devices meet all the requirements of the protocol specification. Our certificate is a guarantee of interoperability with both our →Coiote platform and other popular server solutions.
Advanced features
The commercial license gives you access to additional modules implementing support for bootstrapping from smart-cards and SMS data transport, which are useful for advanced, large-scale deployments.
