DFU failed with sdk15.0.0

[suhaihui]

This how i make it happend:

1.programe softdevice and bootloader.

2.generate app dfu package.

3.upgarde app via nRF Toolbox

4.It's running, all things is seem ok.

5.do the step 3 again, whit same app dfu package.

6.when the dfu finished,it's crushed.

how to fix this?

OK, The application will state that its complete when the image transfer is finished. The update itself will happen after the image has been transfered so one needs to allow some time for the nRF device to update the firmware internally before removing power.
