Hi All,

I am new to the Nano 33 IoT and web editor game so I don't quite understand why a sketch that compiles in the IDE and loads onto the board fine gives me the following error in the Web Editor. I probably missed something really rudimentary but I can't put my finger on it.

Does the Arduino Web editor use a different compiler? In the IDE i have AVRISP mkII. Does that make a difference?

Any thoughts would be helpful. Thanks!

As a TEST only !

Check if you have any additional security / AV that it is turned OFF
Start up CREATE editor.
Plug the board in.
If you get any pop ups for drivers you should say YES.

See if you can upload one of the example sketches eg blink.

If all went well it would be the extra security that is causing problems.
When posting sketches or error messages please use code tags !

The STICKY posts at the top of each forum section also contain additional help.

Could you take a few moments to Learn How To Use The Forum.
It will help you get the best out of the forum in the future.
Other general help and troubleshooting advice can be found here.
It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google (who would have thunk it ! ) or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.
