BLE DFU Issue

[jawadk]

Hi,

I am trying to develop the DFU capability for my device.

I added the necessary code from the example ble_app_buttonless_dfu to my application.

then started as explained in this step by step guide:

https://devzone.nordicsemi.com/nordic/short-range-guides/b/software-development-kit/posts/getting-started-with-nordics-secure-dfu-bootloader#h23sjziacp7vrw0scs2t3tua1ax0426

I flash the softdevice then the bootloader, then DFU the application successfully, but the application doesn't start up at all,

then I tried to debug the application and it is also doesn't start up, it behaves like when flashing the application without the softdevice.

I noticed in the.

when I flash only the softdevice and the application everything works fine when I comment the DFU service and the ble_dfu_buttonless_async_svci_init function.

seems like the bootloader not jumping to the application even after a successful DFU.

Please help

Hi,

tried to DFU the example ble_app_buttonless_dfu with no success.

flashed the softdevice, then the bootloader, then DFU using the nrf connect app on mobile, the application DFUs successfully but the bootloader not activating the application.
