Dongl Bluetooth Dongle
(Final render coming soon)
Stop guessing what's running on your Bluetooth dongle
Untested edge cases, and no direct line to the team that built it means flaky behavior and hours lost to debugging.
SimpleBLE Dongl changes that.
Get full visibility, direct support from the team behind SimpleBLE, and the confidence of a system fully engineered to work perfectly together.
Opaque Versioning
Most Bluetooth dongles you buy online run completely opaque firmware. You have no visibility into what version is running or what bugs it contain.
No Direct Support
When a dongle fails in the field, you have no direct line to the team that built it. You’re left troubleshooting alone with no real answers.
Lack of Customization
You’re locked into the manufacturer’s firmware with no way to tune behavior, optimize for your use case, or fix issues specific to your product.
The official hardware companion to SimpleBLE
We built both the stack and the firmware, giving you direct support from the team, full customizability, and the confidence that your Bluetooth application will simply work from prototype to production.
Full Customizability
Tune the firmware to your exact needs. Adjust parameters, add features, or fix issues specific to your product.
Direct Support
Get direct support from the SimpleBLE team that built the stack and firmware. You’re never troubleshooting alone.
Built for Reliability
Engineered for the SimpleBLE stack. Consistent, stable performance you can ship with confidence.
