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?

I need to know how familiar you are with the SDK to know how detail the instruction should be.

You understanding about micro ecc library was correct. Also, you don't have to do anything with your application if you don't plan to do buttonless DFU. If you want to do buttonless DFU you need to follow Appendix 2 in the blog.

What exactly the issue you are having now ?
