SimpleRsBLE

The ultimate fully-fledged cross-platform library and bindings for Bluetooth Low Energy (BLE).

Overview

The SimpleBLE project aims to provide fully cross-platform BLE libraries and bindings, designed for simplicity and ease of use with a licencing scheme chosen to be friendly towards commercial use. All specific operating system quirks are handled internally to provide a consistent behavior across all platforms. The libraries also provide first-class support for vendorization of all third-party dependencies, allowing for easy integration into existing projects.

Licensing FAQ

Why are you making this change?

So far, SimpleBLE has been a labor of passion with over 4000 hours invested in multiple iterations. The decision to transition SimpleBLE to a dual-licensing model is mainly driven by the kind of products that have been built around it, in particular around notable names in the medical and industrial sectors, which has been both surprising and encouraging. Providing robust support for these diverse and critical use cases is a resource-intensive endeavor which can't be achieved on goodwill alone, especially so when the underlying APIs are also evolving and life having its own plans. By introducing a commercial license, I'm opening a pathway to dedicate more resources to enhance SimpleBLE. Some of the things on the roadmap include:

  • Bindings into more languages and frameworks.
  • Hardware-in-the-loop test infrastructure.
  • Offering bounties and revenue sharing with other developers who contribute.
  • Providing more comprehensive documentation and tutorials.

Despite this transition, I remain firmly committed to the open-source philosophy. SimpleBLE was grown a lot thanks to the feedback of the open-source community, and that foundation will always be a part of the project. The BSD 3-Clause license option ensures continued accessibility for non-commercial and open-source projects, and I pledge to actively contribute to and collaborate with the community whenever possible. Ultimately, the success of SimpleBLE has been fueled by its open nature, and I believe this dual-licensing model strengthens that success by enabling both community-driven growth and targeted enhancements that benefit everyone.

I'm already using SimpleBLE. What happens to my project?

Please reach out at contact at simpleble dot org and we can discuss the specifics of your situation. It is my intention to make this transition as smooth as possible for existing users, and I'm open to finding a solution that works for everyone.

What is offered as part of the commercial license?

  • Prioritized Support: Your feature requests and bug fixes receive top priority.
  • Company Spotlight: Showcase your company logo on our documentation and website.
  • Dedicated Assistance: Get personalized guidance with a few hours of one-on-one support for in-depth implementation or debugging challenges.

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. The key factor is the use of the library as a component in a revenue-generating or business-advancing context, irrespective of whether the library itself is sold or offered as a standalone product.

What do you consider "derivative work"?

A derivative work, in relation to SimpleBLE, refers to any software or application that includes, builds upon, or modifies any part of the SimpleBLE library. This encompasses not only direct modifications of the library's source code but also software that incorporates the library as a significant functional element. For instance, an application that uses SimpleBLE as a foundational component for Bluetooth connectivity would be considered a derivative work. The commercial use clause applies when such a derivative work is used for commercial purposes, as previously defined. It's important to note that mere usage of SimpleBLE as an incidental component does not necessarily constitute a derivative work, especially if it does not form a significant part of the application's overall functionality or value proposition.

What does the GPLv3 license imply for my commercial project?

The GPLv3 license ensures that end users have the freedom to run, study, share, and modify the software. It requires that any modified versions of SimpleBLE, or any software incorporating it, also be distributed under the GPLv3. Essentially, if your project incorporates SimpleBLE and is distributed, the entire codebase must be open-source under the GPLv3.

You can find the full text of the GPLv3 license at GNU GPLv3.

What does the BSD 3-Clause license imply for my project?

The BSD 3-Clause license is a permissive open-source license that allows you to use, modify, and redistribute SimpleBLE in your project, whether it's open-source or proprietary. It does not require that your project be open-source, and it does not impose any restrictions on how you use SimpleBLE in your project. The only requirement is that you include the original copyright notice and license text in any distribution of SimpleBLE or its derivatives.
