or was afraid of.
Let me ask this:What happens if I add one Serial.readBytesUntil() to the program to wait for serial input; not knowing when the input will be received?
It's all the things that you don't want but I guess that you already figured that out.
You have received a lot of advice that you do not seem to have been able to make use of so you need to post your complete program so we can understand what you are having a problem with....R
Actually I haven't received any "advice...to make use of".
Maybe read reply #3 again.
OK. Read it again. Still haven't received any "advice...to make use of". Reply #3 is almost irrelevant at Robin2 doesn't like serialEvent() and provides no examples to that end.
