Introducing the SimpleBLE Dongl

SimpleBLE Dongl is finally live!

TLDR: We're releasing the SimpleBLE Dongl—a suite of hardware and firmware products. Say goodbye to obscure OS quirks and hello to an extremely consistent BLE experience across every platform.

Deep dive into the SimpleBLE Dongl

Today, we're sharing something a bit different from a normal library release. Instead of depending on whatever Bluetooth behavior Windows, Linux, or macOS decides to expose on a given machine, Dongl moves that complexity out of the host and into a system we control end-to-end.

If you’ve worked on BLE products for a while, you already know the problem. Your application behaves differently depending on the OS, the adapter, the driver version, or some obscure stack quirk that only shows up on one customer's machine. That is where a massive chunk of development and debugging time disappears.

Dongl is our answer to that.

What’s included in the suite?

• Firmware (N Series): Available right now. You can flash it onto any board based on the nRF52840 chipset. It is completely free for prototyping, testing, and non-commercial validation.
• Hardware (N Series): Coming soon. This will be our official dongle engineered from start to finish for production-grade reliability.

This means you can start validating ideas right away with hardware you may already have on your desk, and later move to an official, production-oriented option without changing direction. For Dongl specifically, the N Series firmware is free for prototyping, testing, and non-commercial validation. Commercial licensing is available for production environments.

Why does this matter?

By bypassing the host BLE stack entirely, Dongl gives you a much more predictable foundation for BLE products and internal tools.

That means:

• More consistent behavior across platforms.
• Full visibility into what the firmware is actually doing.
• Fewer hours lost trying to figure out whether the problem lives in your code, the adapter, or the operating system.

For teams using Dongl in commercial environments, it also brings the ability to tune parameters, add product-specific behavior, and get direct support from the team that built both the software stack and the firmware.

A lot of Bluetooth tooling is good enough for prototypes, but production is where things get painful.

Our goal with Dongl is to remove that guesswork and give developers something they can actually trust.
