Hi,
yesterday i blinked for a first time.
Today i tried different codes and with that i couldnt connect to Blynk server.
Then i tried with yesterday’a working sketch(minimal blink example for USB) and i got same error at script.
Error code is 11001.
Did you check which COM port the Arduino is using and edit your USB script?
The COM port number may change if you are using a different USB port on your PC.
Pete.
Thanks Pete.
You cant get error 11001 with that.
So yes, i’ve checked it and no problem there.
