A simple program allows to upload compiled sketches (Intel Hex) to Arduino using only Bluetooth or USB

A Hex file is selected with integrated file manager or shared directly from other applications and transmitted over the Bluetooth connection or USB Cable via the bootloader.

Tested on Arduino Uno, but it should also work on other boards.

IoTool Arduino Sketch (hex) Uploader is part of IoTool - The smartphone IoT platform (www.iotool.io).
