I'm sorry. I closed this question and can't reopen. I need more answer. If I solve all problem I'll close this question.
As you mentioned I'll try HW version modification. And I'll add the result.
Hello,
I have some problem in DFU. I ask this again. I did as below.
-

-
bootloader_secure compile with dfu_public_key.c(made in process 2) and bootloader setting file make nrfutil settings generate --family NRF51--application nrf51422_xxac.hex --application-version 3 --bootloader-version 2 --bl-settings-version 1 settings.hex

I try DFU in android phone. I can see DfuTarg. But, It fails to DFU app_dfu_package.zip(made in process 3).
What’s wrong? I don’t know.
**I want DFU process as below.
- my application run when power on
- bootloader enter(using buttonless_dfu projecs - Already I merged with my application.) after some key input (This key is in my custom board.)
- upload my new F/W using bootloader_secure in android phone.
- my new application run again after DFU done.**
I need your help eagerly.
