Multiple definition error in Arduino demo code

I have a student attempting to compile the nano_ble33_sense_accelermeter example sketch. They get a “multiple definition” error. The entire build output can be found here:

I do not believe they have modified the sketch, and I’m unable to reproduce the error. Any ideas on how to correct this issue?

Hello @ShawnHymel,

Not really sure either where the error comes from but I’d suggest to first try removing all the boards from Arduino IDE and add the Arduino Nano BLE 33 sense again. If the error still persists he should try to do a clean uninstall (removing all the boards and libraries and the IDE) and install only what is necessary again.



I’ll let them know. Thank you!
