You can find a simple example <a href="https://github.com/hubuhubu/nRF52-fds-example">here</a>. You should also be able to find some useful snippets on the forum here.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/116398?ContentTypeID=1Tue, 09 Jan 2018 06:58:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:be484af9-dc07-4e19-b8ca-9ec80bb3390eHust<p>Thank you for your qiuck response.
