Xtimer error with Nano 33 BLE

Hi,

In my code I’m doing something like:

whileloop

which I think makes sense and should work

Anybody have an idea as to why I’m getting this error?

Hi @FrankO! Have you included the xtimer module in your application? This means including USEMODULE += xtimer in your application Makefile.

That was it, thank you so much
