Empty space in first Char of Serial Monitor

Projects Programming

Ok, another one...

For any reason in the first Char of the first line of the serial monitor I always have a blank space.
Any Idea why?

Like:
(Just think of an empty space where the * is. The forum seems to remove empty space at the beginning)

if this means you have another Thread about the same project please keep all the questions in it so that everyone has easy access to all the information.

Any Idea why?

How can we know when you have not posted your code?

And please use the code button </>so your code looks like thisand is easy to copy to a text editor

Print a blank line in setup() to remove any junk data from the buffer.

Another one meant another Question :wink:

I assume this isn't related to my code since I had that with every code until now as far as I remember....

Tried serial.flush but with no result.

Will check if its reallysomething in my code.

Have you tried a Serial.println() in setup() ?

void setup()
{
  Serial.begin(115200);
  delay(10);
}
void loop()
{
  Serial.println("TEST");
  delay(1000);
}

Does it with this code as well.

sure with Println in setup it will look better but that's just a workaround, would like to find the reason.

Ok it seems I found the reason.

I got an ESP8266 hooked up on TX Pin1 (did disconnect Pin 0 already).

as soon as I disconnect Pin 1 it works

It's difficult to spot that sort of thing when you don't tell us or post your code.

Perhaps if your question had been in your other Thread it would have obvious ?
