Licensing

Since January 20th 2025, SimpleBLE is now available under the Business Source License 1.1 (BUSL-1.1). Each version of SimpleBLE will convert to the GNU General Public License version 3 after four years of its initial release. Qualifying non-commercial users may instead continue using and distributing that version under the original BUSL-1.1 terms under the Non-Commercial Perpetual Use Grant in LICENSE.md.

The project is free to use for non-commercial purposes, but requires a commercial license for commercial use. We also offer FREE commercial licenses for small projects and early-stage companies - reach out to discuss your use case!

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
