The ultimate fully-fledged cross-platform library and bindings for Bluetooth Low Energy (BLE).
The SimpleBLE project aims to provide fully cross-platform BLE libraries and bindings for Python, Rust and C++, 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.
NOTICE: Since February 20, 2024 the license terms of SimpleBLE have changed. Please make sure to read and understand the details below.
- SimpleBLE: C++ cross-platform BLE library.
- SimplePyBLE: Python bindings for SimpleBLE. See the SimplePyBLE PyPI page for more details.
- SimpleRsBLE: Rust bindings for SimpleBLE. See the SimpleRsBLE Crates.io page for more details.
- SimpleBluez: C++ abstraction layer for BlueZ over DBus. (Linux only)
- SimpleDBus: C++ wrapper for libdbus-1 with convenience classes to handle DBus object hierarchies effectively. (Linux only)

Since February 15th 2024, SimpleBLE is now available under the GNU General Public License version 3 (GPLv3), with the option for a commercial license without the GPLv3 restrictions available for a fee.
More information on pricing and commercial terms of service will be available soon.

NOTICE: The following projects are allowed to use SimpleBLE under a GNU Lesser General Public License version 3 (LGPLv3), due to their past contributions: BrainFlow, InsideBlue, NodeWebBluetooth.

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 GPLv3 license option ensures continued accessibility for 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.
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.
Commercial use in the context of SimpleBLE refers to any usage of the SimpleBLE or any of its language bindings 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.
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.
