Bluetooth capabilities in minutes.
Not months.
SimpleBLE is the fully supported, cross-platform library designed to get your Bluetooth product to market without the headaches.










































Most Bluetooth libraries aren't built for production.
Many popular libraries work well enough for experiments or prototypes, but struggle when you need reliable, production-grade results. This translates to weeks or months spent troubleshooting instead of delivering your product.

Unreliable Performance
Free libraries are notorious for edge cases. Code that runs fine during testing can break in production due to subtle system differences, leading to panicked hotfixes and unreliable user experiences.

Lack of Vendor Support
When a library error halts development, there is no support team to call. You are left relying on the goodwill of strangers or debugging obscure source code yourself while your deadline ticks away.

Limited Platform Support
Partial platform support forces you to act as a wrapper developer. You end up maintaining three different libraries with three different APIs, creating a tangled mess of conditional logic just to connect a device.
The complete toolkit for Bluetooth development.
From connecting to devices to building custom peripherals, access the most versatile API that standardizes Bluetooth behavior on every OS.
Connect, control, and manage devices across any platform
Stop porting code between platforms. Write your connection logic once and deploy native performance seamlessly across Windows, Linux, macOS, iOS, and Android.
Scan & Discover
Locate peripherals and view their advertising data.
Connect & Pair
Manage active connections and device security.
Read, Write & Stream
Send and receive data via standard GATT operations.
Turn your computer into a virtual Bluetooth device.
Don't wait for hardware prototypes. Use your laptop to mock peripherals, automate app testing, or build unique PC-to-mobile experiences without a single microcontroller.
Broadcast & Advertise
Define custom advertising payloads and control visibility.
Manage Connections
Accept incoming links and handle connection events.
Host Custom Services
Dynamically create GATT services and characteristics.
Take your product to production
Accelerate your roadmap with professional support and specialized hardware designed to work seamlessly with our stack.

Consulting & Support
Direct access to the core team. Don't let technical blockers delay your launch. Get priority support, custom feature development, and architectural guidance directly from the engineers who wrote the code.

Frequently asked questions
SimpleBLE provides a cross-platform, consistent API that works across Windows, Linux, Mac, iOS, and Android, allowing developers to write Bluetooth code once instead of maintaining separate implementations. With native bindings for C, C++, Java, Python and Rust, SimpleBLE is trusted by companies in medical, automotive, entertainment, and security industries. Our clients have consistently reported saving hundreds of development hours, and all feedback highlights the smooth implementation and reliability of our platform.
SimpleBLE offers true cross-platform compatibility, working seamlessly across Windows, Linux, Mac, iOS, and Android operating systems. This means you can develop your BLE applications once and deploy them everywhere without maintaining separate codebases for each platform. Our unified API handles all platform-specific complexities behind the scenes. Additionally, we have some interesting integrations that we’re working on. Stay tuned!
SimpleBLE provides native bindings for C, C++, Java, Python and Rust for Bluetooth Central functionality and C++ for Bluetooth Peripheral functionality, with more language support planned for the future. These bindings are designed to be intuitive and consistent across languages, allowing you to work in the programming language that best suits your project needs while maintaining the same simplified BLE interaction model.
SimpleBLE is widely used for developing cross-platform device management tools, firmware update systems, and product configuration interfaces. It's particularly valuable for building automated test suites, quick firmware validation tools, and product SDKs. Our platform has proven especially successful in medical, automotive, entertainment, and security industries.
You need to purchase a license if you’re using SimpleBLE 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 process to obtain the license for SimpleBLE is easy and straightforward. You can simply issue a purchase order indicating the type of license you want, the product capabilities and business size. You can also contact us to sign the License Agreement and we’ll go from there.
Yes, even in the case where you qualify for the Startup package, you need to sign the License Agreement to obtain the commercial license for SimpleBLE.
The main difference between the Development and the Unlimited license is its duration. The Development license is valid for 1 year, while the Unlimited license has no expiration date, which makes it easier for larger enterprises to purchase as they don’t need to renew the license every year.
At the moment, we only accept payments via bank transfer and checks. We are working hard to offer more options in the near future.
We do provide discounts if you purchase multiple products or multiple capabilities for a given product. Please contact us to find out more information.
SimpleBLE offers two different consulting services specifically tailored to meet your development needs. SimpleBLE Consulting provides guidance for integrating SimpleBLE into projects, while AdvancedBLE Consulting offers end-to-end solutions. Whatever your BLE development goals, we have the expertise to help you succeed.
