You should be able to continue debugging when the bootloader starts the application after the update is complete. I would also recommend you compile your app with the DEBUG flag so you can catch errors before it starts to reboot.

Yes I did and tested it using Ble_app_uart and then converted that using Nrf_serial_uarte it was working fine, but my product is build using freeRTOS , in that it is sending data first but later not however it is reading on ble correctly

Hi,

Please try to debug your application after completing DFU to find out what causes it to reboot. Unexpected resets are usually caused by errors being passed to the APP_ERROR_CHECK() macros in the app (Error module).

Have you made any changes to the initialization of this characteristic since you started getting his error?
