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,

Have you tried the ble_app_hrs_s310_with_dfu example in the SDK ? What did you do in the modification of your application ? Have you followed this ?

Could you point me out to the s310 example in the SDK? I could only find the s130 dfu examples . Which version of the SDK is the s310 used or referred?

Hi vsvdd,

You may want to use SDK v10. You can download it here.

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.

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.
