@Erel,I had those two lines code,The board is UNO,I think the log function should call the serial print in debug mode,but the BXR IDE only have release mode,No any message output in log window.
Bye the way,which bootloader should be the best choice in B4R?I had installed the optiboot in my target.
I don't get any output to the log window (B4R 1.50)
Board is Nodemcu 1.0
I have included as recommended
Serial1.Initialize(115200)
Log("AppStart"
The baud rate is set to the same value.
Log is set to "IDE".
The code itself works as seen by the updating graph on an OLED.
With a simple test code it worked.
After that it also worked with the original program, strange.
The reason could not have been the rebooting of the PC this morning. I had tried that yesterday too (but yesterday not switching off power unlike this morning).
Thank you.
