Where is nrf_dfu_set_adv_name_init defined?

[rolandash]

Seems i can not find where nrf_dfu_set_adv_name_init is defined? It seems not in SDK source files, neither can find any sign on SDK documents.

Thank you.

Hi Rolandash,

nrf_dfu_set_adv_name_init is defined by the Asynchronous supervisor function interface NRF_SVCI_ASYNC.

You can find this macro in ble_dfu_unbonded.c

NRF_SVCI_ASYNC_FUNC_DECLARE(NRF_DFU_SVCI_SET_ADV_NAME, nrf_dfu_set_adv_name, nrf_dfu_adv_name_t, nrf_dfu_set_adv_name_state_t);

"The async interface provides a method to call into a external application through the SVCI interface without relying on allocated or reserved memory inside the external application."

Basically it's the call from the buttonless application to the bootloader to write the advertising name that the application want the bootloader to advertise. You can find the call nrf_dfu_set_adv_name() in set_adv_name() inside ble_dfu_unbonded.c. This call will trigger nrf_dfu_set_adv_name_on_call() inside nrf_dfu_svci_handler.c in the bootloader.

I would assume the queuing of the log would be delayed because the SVC call but I don't think the log would get lost. But be aware that we usually call the SVC to write bond information and advertising name right before we reset and switch to bootloader, could it be the reason you see the log missing ?
