ble_app_buttonless_dfu example.

[maK]

Hello.
Please understand that I'm not good at english.
I can't put device to buttonless example.
Execution environment :

• nrf-sdk 13.1.0
• softdevice 4.0.2
• nrf52832
• macOS
  sequence :

1. flash softdevice : nrfjprog --program s132_nrf52_4.0.2_softdevice.hex -f nrf52 --sectorerase
2. build public_key.c + bootloader_secure_ble = bootloader_secure_ble.hex
3. flash bootloader_secure_ble.hex
4. build experimental_ble_app_buttonless_dfu : ble_app_buttonless_dfu.hex
5. flash ble_app_buttonless_dfu.hex
   then, I can't find an entry in list that DEVICE_NAME is "Nordic_Buttonless".
   but, instead of steps 4~5, If I do the following, Nordic_Buttonless App will work.
6. ble_app_buttonless_dfu.hex + private.key = ble_app_buttonless_dfu.hex.zip
7. DFU through the Android app nRF Connect.
   then, I can find a "Nordic_Buttonless".
   Q1. In above and below methods, I want to know how to do it in the above method.
   Q2.
8. mergehex -m ble_secure_bootloader.hex ble_app_buttonless_dfu.hex -o output.hex
9. flash output.hex
   then, I can't find a "Nordic_Buttonless".
   Why not?

Q1: Have you followed the secure dfu bootloader blog post? These two links could also be useful: link 1 & link 2. Let me take a closer look and get back to you.

Q2: See the secure dfu blogpost I mention above. It is not possible to merge the Bootloader and application and flash the output hex file at the same time. You will need to create two separate zip files and flash them separately to the device.

I solved problem, I missed to generate bootloader settings file. infocenter.nordicsemi.com/index.jsp

Great! Good to hear you figured it out. And thanks for updating the case! Could be helpful for other people in the future. :)
