https://devzone.nordicsemi.com/f/nordic-q-a/73668/nrf5-sdk-v16-0-0-nrf-mutex-lock-functionHi there, I am using nrf_mtx_trylock. The explanation of nrf_mtx_trylock is &quot;Try to lock a mutex.&quot;. I would like to lock a mutex forcibly. Does the function which locks a mutex forcibly exist?

Would that not defeat the purpose of the mutex?</span></p> <p><span>Best regards,<br />Jørgen</span></p><div style="clear:both;"></div>
