Most efficient/smart way of persisting characteristic values on nRF52https://devzone.nordicsemi.com/f/nordic-q-a/19759/most-efficient-smart-way-of-persisting-characteristic-values-on-nrf52Hello, Can anyone help me figuring out the best possible way to store certain characteristics which I want to never reset values on the events of controller RESET or power cycle (OFF/ON). The only way to reset those characteristics must be through flashen-USTelligent Community 13Fri, 17 Feb 2017 10:48:49 GMTRE: Most efficient/smart way of persisting characteristic values on nRF52https://devzone.nordicsemi.com/thread/76836?ContentTypeID=1Fri, 17 Feb 2017 10:48:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:20db8b52-1610-4d8c-bcc0-c8691b963800Petter Myhre<p>If you are using Peer Manager you are already using FDS (and Fstorage), so I would recommend to only use this. Device Manager uses Pstorage which could conflict with Fstorage.</p> <p>There are some threads in here on how to use FDS to store application data. I would just update the data in flash every time a characteristic value is written to, and then every time the device starts up set the characteristic values with sd_ble_gatts_value_set().</p> <p>FDS implements wear leveling, so the flash endurance shouldn&#39;t be a problem, this if course depends on how many writes we are talking about here.</p><div style="clear:both;"></div>
