Hi Pavan,

the steps to perform DFU with the sample DFU images in the SDK are given on this Infocenter page.

Best regards

You need to flash both the bootloader (found in examples\dfu\bootloader_secure_ble\pca10056) and the S140 SoftDevice (found in components\softdevice\s140\hex) to your board in order to perform a DFU with the sample images found in examples\dfu\ble_dfu_send_hex\test_images_update_nrf52840.
