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.

If you don't have any application flashed, the bootloader will detect that and will enter bootloader mode and wait for DFU update. Still could you describe what the problem you have now when following my guide ? Please try to test without any modification, the device should advertise as DFUTarg, you can check it using nRFConnect app on the phone or PC.
