There will be no code generated for those marked lines if NRF_SDH_BLE_PERIPHERAL_LINK_COUNT is set to zero. Which it is in your 7z file in your first post.

If the compiler refuses to generate code, there will usually be a good reason.

For the release notes of each nRF5 SDK you should find which versions of tools were used, I suggest to check if you can download those in specific. Also I suggest to try another example for comparison.

I've tried this way before, but the no code for breakpoint is still in the project.Do you have any other suggestion？

You can either compile with debug configuration and/or change the optimization on specific files like this:

Yes，I open the project as-is without any modifications in options.

[quote user="helen"]2、There is no code for breakpoint in the project and ble_nus_c_string_send() isn‘t called by project.And It is not invalid to set the optimization level to 0.[/quote]

Does it happen if you open the project as-is without any modifications?

1、

The reason is as what you say，thank you.

2、There is no code for breakpoint in the project and ble_nus_c_string_send() isn‘t called by project.And It is not invalid to set the optimization level to 0.

Did you change the code in ble_nus_c.c?

It looks to me like the err_code variable is uninitialized, thus you read a random value off the stack memory.
