https://devzone.nordicsemi.com/f/nordic-q-a/47001/how-safe-is-it-to-use-fds-long-term-on-nrf9160It looks like that 1Mb flash is useful for people like me who don&#39;t want to worry about external flash. The question I have is how aggressively I can use the storage? It only has so many writes, just like anything. Is it safer than rewriting to eepromen-USTelligent Community 13Thu, 09 May 2019 09:16:47 GMThttps://devzone.nordicsemi.com/thread/186122?ContentTypeID=1Thu, 09 May 2019 09:16:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0f16c30d-b990-4403-96ae-13bb8cc7916eSimon<p>There is an example using NVS located here:&nbsp;ncs\zephyr\samples\subsys\nvs.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/185824?ContentTypeID=1Wed, 08 May 2019 05:53:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4c5f65d0-a2c8-468a-b9f4-232b3d4850cfrkguy<p>Great thank you.
