Serial DFU example uses softdevice

[Joe]

Hi,

There is an example of serial DFU without using softdevice, and there is a BLE DFU using softdevice. Is there an example for serial DFU that uses softdevice? If not, what may be the steps to have one like that? Use SDK15.3, nrf52832 and Segger Embedded Studio.

Thanks!

I tried to start from the pca10040_uart_debug project, 

Add defines:
  BLE_STACK_SUPPORT_REQ0
  NRF_SD_BLE_API_VERSION=6
  S132
  SOFTDEVICE_PRESENT

Remove from project:
  components/drivers_nrf/nrf_soc_nosd/nrf_nvic.c
  components/drivers_nrf/nrf_soc_nosd/nrf_soc.c

Add to project:
  components/libraries/fstorage/nrf_fstorage_sd.c

It complies and run in the debugger, but it seems to reset in the middle of writing the objects....

Hi Joe,

I found this similar case:  How to merge serial and BLE DFU without flow control?

Let me know if the information in that case were not able to solve your issue.
