iOS NRF52832 DFU issue

HI Deadpoolcode,

Judging from the log output it seems that the NRF is encountering a non-zero return code from one of the functions inside nrf_dfu_settings_init(). Can you run the bootloader in a debug session and see if you can identify the function that returns the non-zero return code? Set breakpoints in i app_error_handler() and/or app_error_handler() and then look at the call stack.

Best regards

Bjørn

OK, managed to print debug:

<info> app: Inside main
<debug> app: In nrf_bootloader_init
<debug> nrf_dfu_settings: Calling nrf_dfu_settings_init()...

nRF5 SDK version: nRF5_SDK_15.2.0

iOS version: 12.4.1

update package: SD+BL+APP

it fails immediately.

I have used the boot-loader debug version, I do not see any log, where and how should I get it?

Which iOS version are you running on the iPhone 6? Which nRF5 SDK version are you using on the nRF side?

Please post the log from nRF Connect on the iOS device and the debug log output from the nRF device. Note: You will have to use the debug version of the bootloader to get the log output.

Also a short description of how the DFU fails? When does it fail, immediately, halfway or at the end? Are you performing a application, SD+BL update or SD+BL+APP update?

Best regards
