Hello, environmental engineering is D: Lianxi nrf522 nRF5_SDK_15.2.0_9412b96 examples ble_peripheral ble_app_buttonless_dfu

You can't run this ble_app_buttonless_dfu after you download the protocol stack

Return error at breakpoint

Use this project to test DFU upgrade.

Looking forward to your reply, thank you.

Hello,

The bootloader must be present in order to initialize the SVCI interface to bootloader. I'd recommend you to go through the blog post here to get started with DFU: https://devzone.nordicsemi.com/b/blog/posts/getting-started-with-nordics-secure-dfu-bootloader

1.Hello, thank you for your reply, but there are still some problems. A warning appeared when using D: Lianxi nrf522 nRF5_SDK_15.2.0_9412b96 examples dfu secure_bootloader pca10040_blebleblet to do settings.

Use the command nrfutil.exe settings to generate -- family NRF52 -- Application nrf52832_xxaa_bootloader.hex -- application-version 3 -- bootloader-version 2 -- bl-settings-version 1 bootloader_settings.hex

Help to find out what the problem is, feel your reply, thank you.

2.When -f is downloaded, there is no such command.

Is the edition low? How to upgrade the new version?

Yes, that's a pretty old version. You can download the latest one here: https://www.nordicsemi.com/eng/nordic/Products/nRF52-DK/nRF5x-Command-Line-Tools-Win32/51499
