DFU over Bluetooth - Modify the Peripheral LBS sample error

[selfcontrol]

Hi,

I have a question regarding the DFU example

---

Board used: nRF7002dk
Toolchain used: v2.6.1
SDK used: v2.6.99-cs2
OS used: Windows 10

---

I was following the process of 'DFU over Bluetooth - Modify the Peripheral LBS sample' from the link below, and encountered a build error starting from step 2a
(I think I saw a similar example in the intermediate course at the academy.)
https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/software/posts/ncs-dfu#mcetoc_1h90kb1ii2

It is stated that if you use NCS version 2.5.0 or later,

CONFIG_BOOTLOADER_MCUBOOT=y

CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y

only need to add the above.

Below is the build failure log.

Please share a solution for this.
(It seems like the example adding MCUBOOT configuration is encountering the same error.)

Hello,

Apologies for the delayed response. I was reviewing the sample in the DevAcademy, and it appears you need to modify the sample for the nRF7002DK. I recommend checking the Matter sample, which supports FOTA. Please refer to its configuration, as you can adapt it for a non-Matter application. Additionally, refer to this old thread where my colleague shared a working FOTA DFU sample for the nRF7002DK.

Kind Regards,

Abhijith

Hello again, Abhijith.

How will this matter proceed in the future?

It seems that the link for this is incorrect.

I attempted the additional configuration for entering the bootloader as mentioned in the thread, but I encountered build failures, possibly because I did not fully understand the setup method. I have posted about this issue in the thread.

Additionally, there are not many mentions of "dfu with nrf7002dk board" in other threads, which makes it difficult.
Could I request a more detailed guide for BLE OTA, by any means necessary?

Hello,

I apologize for the inconvenience with the previous link I provided for the Matter sample. The issue might be due to ongoing updates on our documentation.

Please try accessing the sample through the link below. Additionally, I am attaching the link for the same sample from GitHub.

Matter light bulb: with FOTA support.

GitHub link to the sample.

Kind regards,

Abhijith
