[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,

Just want to clarify you want to use the examples .zip file inside ble_dfu_send_hex ?

If you want to test the examples, you can follow my guide but skip the keys generating part, you only build the bootloader with the default publickey.c and do DFU via nRFConnect with the .zip samples. Basically you skip step B2 and step C in the guide.

thanks for answer. I just want flash my .hex file by simple method. Without pyton, any key generation... Can I use from ble_dfu_send_hex example for it?

may be possible use some files from this example?

No, there isn't a way to simplify that. It seems to be complicated with all the keys. But when you get used to the routine it shouldn't be too difficult. I suggest you to go ahead and follow my tutorial in the blog, it shouldn't take too long.
