Zephyr. Issues using kernel Events.

I believe the problem is that the event support was not there in version 2.7.0 of Zephyr, which is the Zephyr version used by nRF Connect SDK v1.8.0.

You would have to upgrade to version 1.9.1 of the nRF Connect SDK, which includes a more up to date version of Zephyr.

Hi,

Sorry for the late answer.

I am using the same board as you are : the nRF52840DK.

I am on the 1.8 version.

Edit : I tried your code and I have the same issue. The build returns me this warning and then fail

warning: attempt to assign the value 'y' to the undefined symbol EVENTS

Which version of the nRF Connect SDK or Zephyr are you using?

Which board are you building for?

I had no problems using the event API in a simple project built for the nRF52840DK in nRF Connect SDK v1.9.1, but I need to set CONFIG_EVENTS=y for it to work:
