Hi,

This is not fixed in the deprecated nRF5SDK, but is fixed in nRF Connect SDK. when I look into the sources of the latest NCSv2.6.0, I see this fixed.

Since you are using the nRF5SDK, you need to comment this assert manually in your project.

Hi,

In what SDK was this fixed?

Thanks!

There is a bug in nrfx_timer.c->nrfx_timer_init where there is a check

    NRFX_ASSERT(timer_event_handler);

This check is a bug and you need to comment it our or remove it. It is later fixed in later versions of the nrfx as you can see here.
