Not working without connection to PC

[schms27]

Hi,
great project first of all, thanks a lot :-)
I'm using it with a XIAO ESP32 S3 and it works great so far.

But I noticed, that the code is only working when connected to a PC/Notebook, but not when charged only through USB-C.

I think the issue is here:

void setup() {

  Serial.begin( 115200 );
  while( !Serial );   // TODO - rework all Serial outputs to log_info, log_error, log_debug
  ....

If there is no Serial present, it will wait forever. I commented the line while( !Serial ); in my code and now it works.
Just wanting to let you know :-)

Hmm, I did wonder why is that but since XIAO board gets quite hot I stopped actively testing it.
Gonna research this a bit more, thank you very much!
