nrf_dfu_set_adv_name_init returns 1

[Jeremy]

I'm trying to add the ble_dfu service. During services_init(),

err_code = ble_dfu_buttonless_async_svci_init();
APP_ERROR_CHECK(err_code);
err_code = ble_dfu_buttonless_init(&dfus_init);
APP_ERROR_CHECK(err_code);

In the call to ble_dfu_buttonless_async_svci_init, nrf_dfu_set_adv_name_init returns 1, causing an error.

I have #define NRF_DFU_BLE_BUTTONLESS_SUPPORTS_BONDS 0 in sdk_config.h.

Any help would be great.

Please make sure that NRF_DFU_BLE_BUTTONLESS_SUPPORTS_BONDS is set to 1 in the application sdk_config.h fileand that NRF_DFU_BLE_REQUIRES_BONDS is set to 1 in the bootloader sdk_config.h file.

Why is setting NRF_DFU_BLE_REQUIRES_BONDS required to be set to 1?  I want to support both bonding and not bonding DFU and it sounds like I have to pick one of the other. BTW, I'm finding that if  NRF_DFU_BLE_REQUIRES_BONDS is 0 and NRF_DFU_BLE_BUTTONLESS_SUPPORTS_BONDS is 1 the app hangs forever.

relavak: If NRF_DFU_BLE_REQUIRES_BONDS is set to 0 then the bootloader will notcompile in the asynchrounous SVCI function nrf_dfu_set_peer_data which is used in the ble_app_buttonless_template. If the nrf_dfu_set_peer_data function is called from the application with out being present in the bootloader, then the SVCI call will never return, i.e.e the app will hang forever. 

Yes, you either have to allow DFU with un-bonded peers or only allow DFU with bonded peers.
