on T20 with cameras IDecodeReaderListener onRecvData infinite loop after qr scan

Question

I have two different T20s, one without cameras, one with. Both are running the exact same application and code.

On the T20 with cameras, after successful QR scan,  onRecvData goes into an infinite loop without scanning any further QR codes and the data received = "??".

The T20 without cameras does not do this. It works as expected and waits for another QR scan before onRecData is triggered. 

Do you have any advice on why this happens and how i can prevent it?

Answer 1

Does this happen on our example code as well?

No. I referred to demo code to fix my issue, thank you.
