The Challenge

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

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

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

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.

Our SimpleBLE Solution

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.

01
SimpleBLE Central Mode

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.

02
SimpleBLE Peripheral Mode

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.

03

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 is three steps: reach out with your tier and company details, sign the license agreement we send you the same day, and pay by bank transfer or purchase order on Net 30 terms. Most customers go from first email to fully licensed within one business day. You can also simply issue a purchase order indicating the type of license you want, the product capabilities and business size.

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 is duration. Starter, Growth, and Enterprise licenses are annual: they are valid for one year and renew yearly. The Unlimited license is a one-time purchase with no expiration date, which makes it easier for larger enterprises as they don’t need to renew the license every year. All license types cover your entire company, with no per-seat, per-device, or royalty fees.

There is no kill switch. If your annual license lapses, you retain the right to keep using and shipping your existing applications with the functionality they have at that time. An active license is only required to continue developing, that is, to make changes to how your application uses SimpleBLE or to build new applications with it.

The agreement licenses your legal entity as a whole. It is governed by California law and includes mutual confidentiality. We're happy to send the full agreement text for review before you commit. Just ask, and we'll send it the same day.

Yes. SimpleBLE can be combined with code under permissive licenses such as MIT, Apache 2.0, and BSD-3. Code under GPL or LGPL licenses cannot be combined with SimpleBLE under the commercial license.

At the moment, we only accept payments via bank transfer and checks, on Net 30 terms. We can also work directly from your purchase order. 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.
