BLUETOOTH LOW ENERGY USB DONGLE
BleuIO Pro – Advanced BLE Development Dongle
Bluetooth 5.2 USB dongle for fast BLE application development
BleuIO Pro is an advanced Bluetooth Low Energy USB dongle designed for developers building BLE applications without complex embedded setup. It supports Bluetooth 5.2, extended advertising, AT commands and cross-platform workflows so you can scan, advertise, connect and prototype faster.
Use BleuIO Pro with terminal commands, Python scripts, JavaScript applications or custom desktop tools to build and test BLE workflows on Windows, macOS and Linux.
WHY BLEUIO PRO
Advanced BLE programming without embedded complexity
BleuIO Pro gives developers a practical way to build and test Bluetooth Low Energy applications from a computer. Instead of setting up embedded SDKs and toolchains, developers can use simple AT commands or libraries to control BLE behavior directly from USB.
Extended advertising
Work with extended advertising packets for more flexible BLE communication workflows.
32Mbit QSPI Flash
Store application data and custom settings with more available memory.
Cross-platform development
Use the dongle on Windows, macOS and Linux.
AT commands
Scan, advertise, connect and test BLE behavior from a terminal or application.
Programmable LED
Use LED control for status indication, debugging and visual feedback.
PROGRAMMABLE LED
Visual feedback for testing and debugging
BleuIO Pro includes a controllable LED that developers can use for status indicators, alerts and debugging feedback. This is useful when testing BLE workflows, creating prototypes or building applications that need immediate visual response.
