Undefined identifiers in ble_dfu_unbonded.c when upgrading from SDK 14.2 to SDK 15

[Eric Smith]

I'm upgrading a client project from SDK 14.2 to SDK 15, and running into some undefined symbols in ble_dfu_unbonded.c:

Error[Pe020]: identifier "nrf_dfu_set_adv_name_svci_async_t" is undefined C:\nordic\nRF5_SDK_15.0.0_a53641a\components\ble\ble_services\ble_dfu\ble_dfu_unbonded.c 61

Error[Pe020]: identifier "nrf_dfu_adv_name_t" is undefined C:\nordic\nRF5_SDK_15.0.0_a53641a\components\ble\ble_services\ble_dfu\ble_dfu_unbonded.c 67

The lines in question are

61  NRF_SVCI_ASYNC_FUNC_DEFINE(NRF_DFU_SVCI_SET_ADV_NAME, nrf_dfu_set_adv_name, nrf_dfu_adv_name_t);

67  static nrf_dfu_adv_name_t   m_adv_name;

78  static uint32_t set_adv_name(nrf_dfu_adv_name_t * p_adv_name)

I don't really understand the details of what NRF_SVCI_ASYNC_FUNC_DEFINE does, but it look like it should be defining nrf_dfu_set_adv_name_svci_async_t.

In sdk_config.h, I have BLE_DFU_ENABLED defined as 1, and NRF_DFU_BLE_BUTTONLESS_SUPPORTS_BONDS defined as 0.

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

[Eric Smith]

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.

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.

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

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.
