When a BleuIO Dongle is connected to the USB port, the BleuIO Dongle will start advertising. It will then act as a terminal, taking input and sending data to the Arduino Virtual Com Port. We have used an Arduino Uno Rev. 3 with SparkFun’s USB Host Shield (DEV-09947) for this example. You can get project HERE https://github.com/smart-sensor-devices-ab/arduino_bleuio_example This project based on the ‘acm_terminal’ example in the Host USB Shield Library 2.0 What you will need A BleuIO dongle with firmware version 2.1.0 or later An Arduino Uno Rev. 3 (https://store.arduino.cc/products/arduino-uno-rev3) An USB Host Shield (https://www.sparkfun.com/products/9947) The Arduino IDE (https://www.arduino.cc/en/software) Host USB shield library 2.0 Read more about this project at https://www.bleuio.com/blog/details.php?id=1363&title=Bluetooth-Low-Energy-(BLE)-Tutorial-for-Arduino-using-BleuIO
