License

=======



Since January 20th 2025, SimpleBLE is now available under the Business Source License 1.1 (BUSL-1.1).

This means that the project is now free to use for non-commercial purposes, but requires a commercial

license for commercial use. Each version of SimpleBLE will convert to the GNU General Public License

version 3 after four years of its initial release.



**Why purchase a commercial license?**



- Build and deploy unlimited commercial applications

- Use across your entire development team

- Zero revenue sharing or royalty payments

- Choose features that match your needs and budget

- Priority technical support included

- Clear terms for integrating into MIT-licensed projects



**You can find more information on pricing and commercial terms of service at www.simpleble.org**



For further enquiries, please contact us at ``contact at simpleble dot org``.



**We also offer FREE commercial licenses for small projects and early-stage companies - reach out to discuss your use case!**



Licensing FAQ

-------------



**What does the Business Source License 1.1 allow and restrict?**



The Business Source License allows non-production use, such as development and testing in isolated

environments. However, any use that could be considered production (including internal tools,

revenue-generating projects, or customer-facing deployments) requires purchasing a commercial license.



After four years of the initial release of a given version of SimpleBLE, the license automatically

converts to the GNU General Public License version 3.



**What do you consider "commercial use"?**



Commercial use in the context of SimpleBLE refers to any usage of the library or its derivatives in

a commercial setting where it contributes, either directly or indirectly, to financial gain. This

includes, but is not limited to, incorporating SimpleBLE into commercial software products, using it

in the development of services offered for a fee, or deploying it within internal tools or software

in a for-profit organization where it adds business value.



**Why do I need to pay for commercial use?**



Commercial licensing enables us to sustainably maintain and enhance SimpleBLE, particularly given

its growing adoption in critical sectors like medical and industrial applications. The revenue

from commercial licenses allows us to provide robust support, maintain compatibility with evolving

underlying APIs, and invest in improvements that benefit all users. This includes expanded

language support, better testing infrastructure, and more comprehensive documentation. While

SimpleBLE remains freely available for non-commercial use, the Business Source License ensures we

can continue providing the level of reliability and support that commercial applications require.



**I already have a commercial license. What happens with this latest license change?**



Nothing changes. You can continue using SimpleBLE under the terms of your commercial license.



**I'm using SimpleBLE commercially, but don't have a commercial license. What should I do?**



Please reach out at ``contact at simpleble dot org`` and we can discuss the specifics of your

situation. We have a free commercial license option for small projects and early-stage companies

and very flexible commercial licensing options for larger projects.
