I implement it with sdk 11.0 and a third party core-board.Firstly,I program s132_nrf52_2.0.1 SoftDevice by nRFgo Studio,then I open ble_app_hrs s132_with_dfu(arm4) project by Keil(V4.73),and programen-USTelligent Community 13Wed, 17 Aug 2016 12:32:37 GMThttps://devzone.nordicsemi.com/thread/60261?ContentTypeID=1Wed, 17 Aug 2016 12:32:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:39180f1e-353c-4bde-9ce8-fb6a7efb3f0fAmbystomaLabs<p>Try simplifying the dfu zip generation by not using all the options. Then slowly add back options. Try for starters: nrfutil.exe dfu genpkg --application yourapplicationname.hex yourapplicationname.zip Where of course, &quot;yourapplicationname&quot; is just the local name for the hex file from your build. I&#39;ve have good luck with the nrfutil so it should work for you. Also, if you haven&#39;t tried you should make sure that your program build loads and runs before you zip it by installing via dfu using master control panel on a PC. On the PC version it doesn&#39;t have the check for the dat file that the droid and ios versions have. So using it you can load just the hex file without creating a zip.</p><div style="clear:both;"></div>
