Nordic FDU Update for Buttonless

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.

  • Thank You, Hung. Also,coming back to my question, is there a way to implement a buttonless DFU in an application where the device is going to sleep using sd_power_system_off? To be specific, I want the device to go into bootloader mode during reset, but that is not possible since I'm using sd_power_system_off which puts it in reset mode every time it goes to sleep. Is there any other way to put the device in bootloader mode?

    Thank You.
