https://devzone.nordicsemi.com/f/nordic-q-a/68008/how-to-check-thread-states-in-zephryHi I have created 4 threads in nRF9160 application, I have to go to sleep if none of the thread is running. For this how do I check whether the created threads are running or waiting for an event. If any documentation or any sample code please pointen-USTelligent Community 13Mon, 09 Nov 2020 13:05:25 GMThttps://devzone.nordicsemi.com/thread/279003?ContentTypeID=1Mon, 09 Nov 2020 13:05:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a4cbec9b-2dc8-4608-8a93-bc4a9e985df4Hakon<p>Hello,</p> <p>when no other threads are running on the nRF9160, the Zephyr kernel starts the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/reference/kernel/threads/system_threads.html">idle thread</a> which will trigger the sleep state by default. You might need to have the&nbsp;<a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/kconfig/CONFIG_SYS_POWER_MANAGEMENT.html#cmdoption-arg-CONFIG_SYS_POWER_MANAGEMENT">CONFIG_SYS_POWER_MANAGEMENT</a> option enabled, but it should be enabled by default as far as I know. I don&#39;t think it&#39;s necessary to manually check if there are any threads running.</p><div style="clear:both;"></div>
