NCS OTA DFU failed in nrf52832

[Sunil vignesh]

Hi,

 I am trying to test and develop the DFU-OTA in nRF CONNECT SDK for nRF52832

I followed these link to develop  i am using NCS v1.4.2

1. I have copied the peripheral_lbs code to my workspace

2. Based on the link i have added few things and here i attached the related files

main.c

also added full .zip file here

1447.dfu_app.zip

3. After successful compilation of the code uploaded to the Empty nRF52 DK (there is no bootloader separately added before )

4. Successfully showing the services in the nRF connect APP while entering into DFU

5. On the other-side i have just changed the device name to dfu_nrf_blinky

6. taken the build and app_update.bin is taken to mobile device

7. While initialize the DFU it asked for pairing and also paired with the device with valid key.

8. And on entering to start DFU it was disconnected like this and video is linked below with respective log
