In this tutorial, we will look at how the BleuIO USB dongle can add Bluetooth Low Energy communication to an RP2040 or RP2350 development board.
The project uses the open-source Pico I/O Bridge firmware. It allows a supported development board to work as a USB host for BleuIO. BleuIO scans nearby HibouAir sensors, and the board displays the latest sensor data through a simple browser interface.
The board also creates a small USB network connection with the computer. This means the dashboard can be opened directly in a web browser without installing a desktop application or connecting the board to Wi-Fi. The firmware is written in Rust and exposes its interfaces through a local .local address.
