I have been using the QR reader option on my A22 cell phone without any difficulty since April. The code I use is this:
Code: Select all
QR = barcode.read("Escanear el código QR");
As you can see, CsPro opens the camera for one to look for the QR to detect it. However, about 1 month ago CsPro does not identify the QR. What it does identify on the card is only the barcode but that information is not required.
You may think "maybe the QR is not valid, maybe the image is too small" or something like that, however, if I use the phone camera it does identify the same QR and displays the information.
I can't show you a screenshot of the CsPro when it was working because it was not necessary at that time to save any screenshots, the only thing I could notice is that previously the CsPro when opening the camera did show the small QR identification box and currently it does not show it. I think it could be that CsPro was specifically opening the Qr Scanner on the cell phone because at that time the camera was blocked by a MDM (Mobile Device Management). Now the camera is enabled and does not identify it.
If you have any solution or proposal please let me know and thank you.
