Thanks! I saw that in another case (probably yours), but haven't yet had a chance to try it. I expect to revisit this on Wednesday or Thursday, and will report back here.

I use GCC to compile and I added these flags to my make file to fix the problem. Hope it helps

CFLAGS += -DNRF_DFU_SVCI_ENABLED
CFLAGS += -DNRF_DFU_TRANSPORT_BLE=1

ASMFLAGS += -DNRF_DFU_SVCI_ENABLED
ASMFLAGS += -DNRF_DFU_TRANSPORT_BLE=1

i greped SDK14.2 and SDK15, both seemed to use it in a similar way and i could not find the actual define. Please look into this thread.

seems like there is a missing preprocessor define in your project setting.

Thanks! However, now that I've read the migration guide, I still don't have any clue what is causing these symbols to be undefined. My project compiles unmodified ble_dfu.c, ble_dfu_bonded.c, and ble_dfu_unbonded.c from the SDK directory. They compiled fine with SDK 14.2, but with SDK 15.0 I get the undefined symbol errors.

You need to follow the migration guide given for SDK15. You can find this here
