DFU example doesn't work. need explain step by step

[Mikhail]

Hi!

nRF52. S132, SDK13.

I try to use ble_dfu_send_hex example.

1. what shoul I do first? via nrf gostudio load SD. correct?

Which SD? from this folder (dfu_test_softdevice_s132) Or usual SD (s132_nrf52_4.0.2_softdevice)

2. what should I do next?

Hi Mikhail,

Please follow the documentation on inforcenter, you can also follow my step by step guide here.

Maybe you should turn on Logging and check what is in the log. You can switch the log on in the SDK_config.h.

Also you can add breakpoint inside the bootloader to check what goes wrong. You may need to set optimization level to 0 to debug.
