Thanks for your reply !
Stupid me, thanks for the correction. But unfortunately that doesn’t solve the issue. The unreliable behavior also occurs if i just send the signal for i.e “btnXForward”.
To describe the unreliable behavior again: The byte stream (in jSon) format gets recieved correctly (im printing it out on the command window), but the “signal lamp” (the red or green circle) does not always blinks red or green when it should be. Its strange, because it always prints the correct stream in real time, but the image does not show according to that.
Maybe the frame rate is to high, that the image could not be loaded fast enough? Any thoughts?
