peer manager and FDS fullhttps://devzone.nordicsemi.com/f/nordic-q-a/73170/peer-manager-and-fds-fullRecently, I&#39;ve found that the peer manager sometimes wrote specific information so many times until the FDS storage went full. An example data in the storage is as follows: 08C0 0400 01C0 0000 FE14 0000 (FDS header) 0300 0000 0800 1000 0200 0100en-USTelligent Community 13Fri, 26 Mar 2021 04:49:13 GMTRE: peer manager and FDS fullhttps://devzone.nordicsemi.com/thread/302042?ContentTypeID=1Fri, 26 Mar 2021 04:49:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:58d0275a-c98d-413f-9e8f-5143d1ea2915Min-Joon Kim<p>Thank you for your kind answers, Vidar.</p> <p></p> <p>Actually, it&#39;s not easy to catch the right time to do garbage collection.</p> <p>However, according to the articles you mentioned,</p> <p>I guess it would be good to add flash check code prior to starting advertising.</p> <p></p> <p>Best regards,</p> <p></p> <p>Min-Joon Kim.</p><div style="clear:both;"></div>RE: peer manager and FDS fullhttps://devzone.nordicsemi.com/thread/301866?ContentTypeID=1Thu, 25 Mar 2021 10:53:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:409848d1-a2a3-4ea5-a220-c9b87f1854cdVidar Berg<p>Hello,</p> <p>Maybe the GATT client is updating the CCCDs on every re-connect as discussed it this thread: <a href="https://devzone.nordicsemi.com/f/nordic-q-a/64609/peer-manager-and-fds-new-records-at-each-connection">https://devzone.nordicsemi.com/f/nordic-q-a/64609/peer-manager-and-fds-new-records-at-each-connection</a> ?</p> <p>But when FDS is full, do you perform <span><a title="Garbage collection" href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/lib_fds_functionality.html?cp=7_1_3_16_1_2#lib_fds_functionality_gc">Garbage collection</a></span> to free up space again? You can use the fds_stat() function to determine when it&#39;s time to run garbage collection as mentioned in this post <a href="https://devzone.nordicsemi.com/f/nordic-q-a/72920/peer-manager-and-use-of-fds-to-store-app-settings-in-flash">https://devzone.nordicsemi.com/f/nordic-q-a/72920/peer-manager-and-use-of-fds-to-store-app-settings-in-flash</a></p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
