First of all, congratulations on the scanner and thanks for sharing.

I have created a QR code with colors and the reader does not read it. Can it be configured in any way?

If I try to read the code with the iPhone camera, it does recognize it.

I have done the test at https://www.qrcode-monkey.com. If I create a code in black on a white background, the scanner reads it. If I take, for example, yellow over red background, the scanner is not able to read it.

Thanks!
