I am looking to read and write a small amount of data to the flash for non-volatile storage. I have seen multiple support threads suggesting that when using a softdeviceen-USTelligent Community 13Thu, 09 Dec 2021 12:48:51 GMThttps://devzone.nordicsemi.com/thread/342715?ContentTypeID=1Thu, 09 Dec 2021 12:48:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a681a58a-76c9-4e41-9c0b-b49bf3c4e9addavege<p><a href="https://devzone.nordicsemi.com/members/aryan">Susheel Nuguru</a> could you please follow-up here?</p> <p>It would be great to have a confirm, thanks a lot!</p> <p>D</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/336905?ContentTypeID=1Mon, 01 Nov 2021 14:42:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5445feb8-33d7-4231-b3ed-f9d0534a7ae1davege<p>Hello everyone,</p> <p>I came across this question while looking for exactly the same detail.</p> <p>We are implementing an application based on Nordic Connect SDK v1.7.0 for nRF52840 chip, and using SoftDevice Controller for BLE.</p> <p>The documentation on nrfxlib states that NVMC shall be accessed only via the SoC API provided (here&nbsp;<a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/softdevice_controller/doc/api.html#softdevice-controller-soc">https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/softdevice_controller/doc/api.html#softdevice-controller-soc</a>).</p> <p><a href="https://devzone.nordicsemi.com/members/aryan">Susheel Nuguru</a> can you please confirm that, in case of non bare-metal application, we can directly use standard NVS API from Zephyr to write to Flash?</p> <p>Do you think we can either use NVS backend API(<a href="https://docs.zephyrproject.org/latest/reference/storage/nvs/nvs.html">https://docs.zephyrproject.org/latest/reference/storage/nvs/nvs.html</a>) or the Settings subsystem API(<a href="https://docs.zephyrproject.org/latest/reference/settings/index.html">https://docs.zephyrproject.org/latest/reference/settings/index.html</a>) without any risk of conflict with Radio activity?</p> <p>Thanks a lot.</p> <p>D</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/318328?ContentTypeID=1Fri, 02 Jul 2021 05:04:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6f446eec-d5d3-40e9-a72a-3f31ae1acbe9JustinL<p>Great!!</p> <p>Thanks</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/318253?ContentTypeID=1Thu, 01 Jul 2021 13:45:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8f93cfcb-1287-4775-828e-64b61758a3baSusheel Nuguru<p>Hi,</p> <p>In Zephyr all non volatile memory access makes sure that it schedules the flash operation in between the radio events.&nbsp;</p> <p>In short, you can still call the non volatile API at any time and the internal implementation of that API will make sure that the operation works safely when BLE is enabled.</p><div style="clear:both;"></div>
