Becareful!! Read the information below and you need to download examples on Github: https://github.com/S2I71/usb_otg_bridge_app_inventor/
Demo: Try it before buying the full app but a screen display with 10 secondes delay between each comunication. Baudrate at 115200.
Full Version :
Possibility to change BaudeRate: BAUD300,600,...57600,115200... en App inventor 2
No screen with tempo ; transparent bridge .
Create in 10 minutes your application on your android tablet that communicates with your Arduino USB board.
Download the following example: https://github.com/S2I71/usb_otg_bridge_app_inventor/
Students, teachers, passionate communication discover the first application to control devices FTDI UART with USB connector (Arduino Uno, Mega, Yun, FTDI XBee ...) directly from the development tool APP INVENTOR 2 . (No need for extra Host Shield or Bluetooth. All you need is a Micro USB OTG to USB Adapter.)
USB Bridge for App Inventor 2 allows through a USB OTG cable to achieve a seamless interface between a USB device and the development tool APP INVENTOR 2.
You'll be able to develop your own new applications using the power of app inventor 2 (graphic, sensors, databases ...) and the powers of your devices available (LED RGB, Servo, AX12A, DC Motor...) equipped with a USB UART at 115200 bauds
Use and recycle your old phone using its internal functions instead of using multiple Arduino shield: touch screen display, MP3 player, SD card reader, SMS sending, GPD, GSM,QR Codes, NFC, bluetooth, wifi, various sensors .. .. for your microcontroller based applications. (Arduino, Teensy, XBee ...)
If your device is not recognized, please send me the references Vendor ID and Product ID as the following example to the arduino uno: Vendor ID: 0x2341, Product ID: 0x0001
USB Host mode support on android device and Android 3.1+ are required
Example:Control an arduino uno card with otg usb and APP INVENTOR 2
(Test OK 115200 bauds with an arduino méga ADK board)
In the demo version juste change in app inventor the start activity like this:
change : bp.usbbridge.appinv to bp.usbbridge.appinvDemo
and : bp.usb.bridge.appinventor to bp.usb.bridge.appinventorDemo
Send and receive datas from Arduino with Serial.println(), Serial.print() , Serial.read() in 115200 baud rate or other (full version).
Version Arduino program with Ardublock
