Monitoring Error.

[DutchOrange]

So I have successfully uploaded and monitored the ESP32 (Hello_World), But now when I try Monitor the the Blink Example I see one message then it gives a Error. Any Ideas why the Blink E.g will do this ?

Code: Select all

Turning off the LED, Test 2
Exception in thread Thread-2:

Hi DutchOrange,
this may be due to:

• use of the wrong serial port
• another program using the serial port
• bad USB connection or cable
• the USB device resetting

Please verify you are using the correct COM port.
If that doesn't help, then try a different USB port and/or another USB cable.
