So from what I understand, you are continuously sending the string where it updates each section of your screen. For instance, Checking XF sets the image on region 1030,665:
Yes exactly.
First question: Are you holding XF in “1” state during a long period?
No, if I push the button, it gets sent only ONE time.
Notice you are using btnXForward.equals(“1”). I suggest that when you extract the value in the parsing process, you also add the trim() function to remove space characters.
Ok thanks! I’ll give it a try. But I think the data is always valid. I printed out the value and the size of it (1 character). So I think, that doesn’t solve the issue.
Meanwhile thank you very much for your advices !
