https://devzone.nordicsemi.com/f/nordic-q-a/76047/ncs-1-5-1-esb-rx-event-doesn-t-wake-zephyr-from-idleWith current ESB implementation I&#39;m not able to delegate radio event to other thread or workqueue. Kernels stays in idle (tickless kernel) and all radio frames are lost. One solution is to disable tickless kernel or implement direct ISR according to Zephyren-USTelligent Community 13Thu, 17 Jun 2021 14:58:13 GMThttps://devzone.nordicsemi.com/thread/315937?ContentTypeID=1Thu, 17 Jun 2021 14:58:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:95a748db-b9e9-4edc-98ad-28c91951b49aovrebekk<p>Hi again</p> <p>The developer confirmed your findings, and will ensure that we patch this in a future update.&nbsp;</p> <p>Once again thanks a lot for bringing this to our attention <span class="emoticon" data-url="https://devzone.nordicsemi.com/cfs-file/__key/system/emoji/1f642.svg" title="Slight smile">&#x1f642;</span></p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/313970?ContentTypeID=1Mon, 07 Jun 2021 14:19:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f443db82-7e34-4f1b-995a-a71cb4d7c52aovrebekk<p>Hi Wojciech</p> <p>Thanks a lot for the heads up <span class="emoticon" data-url="https://devzone.nordicsemi.com/cfs-file/__key/system/emoji/1f642.svg" title="Slight smile">&#x1f642;</span></p> <p>This might be an oversight when the ESB library was ported from the nRF5 SDK.
