Hi,

Please use the insert code function when attaching build logs. It makes it far easier to navigate your case if you do so. And also thank you for providing steps to recreate what you see unprompted. That helps speed up the process.

[quote user="snowuyl"]Thanks for your reply! I try to build mcuboot_smp_ble project as you suggested. But it failed to build with a lot of undefined symbols.[/quote]

This is due to the sample not being compatible with NCS v2.4.0 as I mentioned, which is also the reason for why I supplied you with the second bluetooth smp sample from the zephyr, sample repository:) The error messages you see is due to there being changes in between version and due to missing configurations.

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/subsys/mgmt/mcumgr/smp_svr/README.html

The zephyr sample I mentioned works out of the box for nRF5340DK and in NCS v2.4.0. What you need to do know is to use this knowledge and these two samples to create your application. Everything you have to make it work is mentioned here.

You can base your application on the Zephyr sample alone
You can use the Zephyr sample to cross examine mcuboot_smp_ble sample from the github repository and see what requirements you need to make it work.
1. For instance, one step to make mcuboot_smp_ble to work is to copy the contents of prj.conf and overlay-bt.conf from the zephyr sample and paste it in mcuboot_smp_ble's prj.conf.

2a. will leave you with something like the following configuration. Do note that this configuration is in no way optimal, but it shows how you can easily use something from one sample, to make another sample compile, build and test for you to continue debugging and developing.

Hi,

I see you're using NCS v2.4.0. The blog you mention is quite old now and the samples and modifications are not relevant for anything newer than NCS 2.0.0 at best. I recommend you have a look at the samples at https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples, for instance the smp over bluetooth sample here https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/smp/mcuboot_smp_ble as well as https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/subsys/mgmt/mcumgr/smp_svr/README.html to see how to add DFU support over BLE to your application.

Let me know if you're able to get the smp_ble sample from the git repository I linked to work in NCS v2.4.0. Currently it is verified to work with v2.3.0 and v2.2.0 depending on the tag you check out from the repo.

Kind regards,
Andreas
