How to make a BLE/ESB APP for DFU？

[wzszzxj]

Hi，All：

  I have  finished  a DFU  updater,  But  how to make a  BLE/ESB  application  to test it  with SES?    I just  want to  do it with no util.

Hi 

Do you mean you want to implement a DFU client with a Nordic DK, and transfer the DFU data from one Nordic device to another over BLE or ESB?

Best regards

Hi，Overbekk:

     thank you! Now  I  just  make a USB  bootloader.  But how to make a BLE image by SES?  When I compile the project,It does not combine the softdevice! how?

Hi

You can use nrfutil to combine the SoftDevice  and application hex files. 

nrfutil is documented here. 

Best regards
