bootloader ble example doesn't work.

[maK]

Hi.
When I make flash bootloader_secure_ble, it does advertising well.
And I run DFU by making bootloader_secure_ble into .zip file.
However, it does not advertise bootloader_secure_ble.
So I have to force Button4 + Reset.
I referred to devzone.nordicsemi.com/.../.
Why does not it advertise?

Did you flash the softdevice before you flashed the bootloader? Have you taken a look at the comments in the blog post you mentioned? Have you tried restarting bluetooth on your phone & start scanning again in the nrf connect app on your phone? Also, have you taken a look at the Nordic Infocenter regarding this SDK example?
