https://devzone.nordicsemi.com/f/nordic-q-a/62801/how-to-read-all-the-data-stored-in-the-flashI have written two functions to write and read data from the flash using flash_fds module. In this way I am calling the function to write the data to flash : fds_write_record(1243658723, 39, &quot;AABBCCDDEEFF&quot;); fds_write_record(2243658723, 29, &quot;AABBCCDDEEFFen-USTelligent Community 13Mon, 22 Jun 2020 13:36:18 GMThttps://devzone.nordicsemi.com/thread/256209?ContentTypeID=1Mon, 22 Jun 2020 13:36:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:35515c49-5555-4d5f-a225-6e85ccb20c8bEdvin<p>Hello,</p> <p>So what does your fds_write_record() look like? I assume it uses&nbsp;fds_record_write() in some way? And hence that it uses some sort of record descriptor,&nbsp;fds_record_desc_t?&nbsp;</p> <p>What do you pass on to fds_record_open? Remember that it will look for the record with that same descriptor.&nbsp;</p> <p>Have you seen the <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.0/lib_fds_usage.html" rel="noopener noreferrer" target="_blank">user description on infocenter</a>?</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
