[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.

Before you test something like that, please make sure bootloader works, do what i described in the guide, all the step. And let me know if it works. I can't follow you if I don't know what you have tested and what you have not. Also please check appendix 1, you need to create the bootloader setting hex to be able to flash with Jlink.
