Nextion Debug Mode

Hi all

I’m debugging my Serial Comms between my Adruino Mega and Nextion Editor (Simulator), with “User MCU Input” selected. All is fine, but I get that sometimes when the Arduino sends something eg: btTest.val=1 (btTest is a Dual-state button) the word “Parse:” would turn red without any error message.

The same when the Simulator sends something to the Arduino eg: prints “DComTest”, “Parse:” would also turn red without an error Message.

Would anyone know why this would happen?

Thanks
