I am trying to look up the feasibility of this project I have conceived. The idea is to scan a QR code and send the decoded information (text) to an Arduino via Bluetooth. I have tested out a terminal program on an Android device that can successfully send textual information entered through a keyword on the terminal screen to Arduino (displayed on the serial monitor). I am wondering if there's a way to get this info from scanning a QR code instead of typing it in.
James, I think what iqra is trying to accomplish is to scan the QR code with the phone, process it in the phone and then automatically transfer it through Bluetooth to Arduino in simple text form to further process it there.
If that is the case, this is an android programming question and doesn't have much to do with Arduino. The only Arduino part is doing the standard serial stuff to receive data.
