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?

@Mikhail: Please create a new case, this case is pretty long now. If you see something doesn't work you need to explore the code and figure out why. I can't explain everything for you step by step. If you want to switch from application to bootloader, please try to test with the buttonless example included in the SDK and use exactly the same what we do there.

Thanks for Your help.
