Hi Johan - I was hoping you could enlighten me on which of your barcode libraries I should be using, and perhaps entice yo to edit your original posts on some of the older libs so we don't spend time on them. I found QRCodeReaderView and NewQRCodeReaderView but had issues with both.
I use B4A to write applications for geophysical equipment. Runs on tablet, connect to Arduino mega using Bluetooth. Arduino used as data logger/controller.
My email is email@example.com I can email you more info.
