The nRF52832 chip and SDK12.3.0 implement the buttonless DFU function.

[Aser]

The nRF52832 chip and SDK12.3.0 implement the buttonless DFU function.

First, as you are guided by the DK board, you have already completed the tutorial.

I tried to run it in the source of my project,
My project device is stopped during the initial setup of the application and it seems to run in bootloader mode.

In my project, I did not call the bootloader mode setting function, but only added the header file and C file.

I want to know the exact reason for this and how to solve it.

Why do I enter this mode when I did not call the bootloader mode function?

 

bootloader mode is running but not advertising.
I'm guessing now that my device's state is bootloader mode, but I'm not sure.

Hi,

I think you are following an old tutorial.  

We have a buttonless DFU tutorial for SDK 15.0.0 which is more up to date here -> https://github.com/gamnes/nRF52832-buttonless-dfu-development-tutorial

Best Regards,

Answer Thank you so much.
I am very happy to receive an answer.

I was watching this tutorial yesterday.
There are two things that I saw when I read this article.
first,
Step 2 - Create our own bootloader using out own private / public keys
In Step 4
"Compile C: \ nRF5_SDK_15.0.0_a53641a \ examples \ dfu \ secure_bootloader \ pca10040_ble \ ses \ secure_bootloader_ble_s132_pca10040.emProject, which is the secure BLE bootloader for nRF52832".
I do not know exactly how this part should proceed with Compile.
Could you tell me more?

second,
The tutorial I gave above is SDK version 15.0.0.
The SDK version I need to implement is 12.3.0.
I have checked the differences between the two SDK versions, but I am not sure if it is possible to implement the DFU functionality in the same tutorial.

Could you help me with these two parts?
