Nordic FDU Update for Buttonless

[vsvdd]

Hello, I have been working on a customised Nordic Board ,and I can't be able to do a DFU. The DFU App_dfu_dualbank doesn't display the DFUTarg Bluetooth profile on the board. Can anyone help? Is there any tutorial to do a customised buttonless DFU?

Softdevice used is s310.

Hi vsvdd,

I assume you want to set the device in system off mode as the application stop, and when you wake the device up the device should enter bootloader ?

To do that you may want to write a flag into flash before you enter system off instead of using GPREGRET. When you wake up, in the bootloader, you can check that flag to know if you need to do DFU or should you start the application.
