You can achieve most rtos features by just using SDK modules like timers, critical sections and interrupts at different priority levels.</p> <p>See <a href="https://devzone.nordicsemi.com/question/78419/freertos-vs-rtx-nrf5-sdk-v11/">this thread</a> for a related answer.</p><div style="clear:both;"></div>
