can anyone help me, please?

Please spend some time reading How to get the best out of this forum.

Which version of the IDE? If not 2.0beta, there will be a button 'copy error messages' in the orange bar above the output window.

  1. Click it and the errors will be copied to the clipboard.
  2. Next paste it here in a reply using code tags (the </> button) as explained in above link.

Please post your sketch

  1. In the IDE, tools -> autoformat; this will properly indent your code.
  2. In the IDE, edit -> copy for forum; this will copy the code including code tags to the clipboard.
  3. Past it here in a reply.

oh thanks for information. i'm new member in here. that problem already completed. i upgrade my arduino IDE to new version.

Out of curiosity, from which version to which version? This might also help others that encounter the same problem.

You should have a solution checkbox under the replies; please click the solution checkbox of the most useful reply so others will know that this problem had a solution.

from Arduino IDE version 1.8.13 to Arduino IDE version 1.8.15. and you dont forget change the board with arduino nano 33 ble in Arduino Mbed OS boards , not at Arduino Mbed OS Nano Boards.
