 Using the PPK 2 board I have noticed that sometimes my device does not go into deep sleep mode between two tasks. I had to implement a lot of flash operations using Mesh configuration, saving some data before and after each task execution.</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 15 Jul 2021 09:28:09 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/77405/what-can-prevent-nrf52840-board-to-go-into-deep-sleep-mode" /><item><title>RE: What can prevent nRF52840 board to go into deep sleep mode?</title><link>https://devzone.nordicsemi.com/thread/320191?ContentTypeID=1</link><pubDate>Thu, 15 Jul 2021 09:28:09 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:618a0275-14d6-4bb3-b509-b206848def64</guid><dc:creator>JONATHAN LL</dc:creator><description>&lt;p&gt;Link to errata:&amp;nbsp;&lt;a href="https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/nrf52840_errata.html?cp=4_0_1"&gt;https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/nrf52840_errata.html?cp=4_0_1&lt;/a&gt;&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Mesh v4.2.0:&amp;nbsp;&lt;a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.meshsdk.v4.2.0/md_RELEASE_NOTES.html?cp=8_6_0_0_0"&gt;https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.meshsdk.v4.2.0/md_RELEASE_NOTES.html?cp=8_6_0_0_0&lt;/a&gt;&amp;nbsp;&lt;br /&gt;&lt;br /&gt;We don&amp;#39;t have a list of the that shows what issues is related to what SDK and HW combination.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Regards,&lt;br /&gt;Jonathan&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: What can prevent nRF52840 board to go into deep sleep mode?</title><link>https://devzone.nordicsemi.com/thread/319729?ContentTypeID=1</link><pubDate>Tue, 13 Jul 2021 09:09:26 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:7bd259f6-150c-4245-ada4-de5a946b4f54</guid><dc:creator>Aduka_27</dc:creator><description>&lt;p&gt;No, I have not, but for sure I will try to find the answer there. I am using nRF52840 (PCA10056 2.0.1), and there are 5 different revisions on the Nordic website. Also, I am using nRF5 SDK for Mesh v.4.2.0. Is there any specific website or correlation between the revision of board and version of development kit??&amp;nbsp;&lt;/p&gt;

There are quite a number of them that can intermittently prevent the chip from going to sleep. I would review the nrf52840 errata and associated SDK release notes to determine which workarounds you may need to implement.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
