How to disable booting log at ncs2.7.0 Serial LTE modem?

[Jeffery]

Hi

Built and flashed ncs2.7.0 SLM application at NRF9151 DK. It will log booting log messages and then "Ready" as below.

Before ncs2.7.0, I found SLM application only logged "Ready" to indicate power on.

I also tried Quick Start apps to program latest SLM to NRF9151DK. It also only logged "Ready" without redundant booting log.

So, how can I modify prj.conf file to remove these log messages?

Hi,

Can you point to exact log messages which you want to get removed?

Can you show the differences between log outputs of flashed SLM from NCS v2.7.0 and SLM from Quick Start?

Best regards,

Hi 

1. Remove blue color part. For ncs2.7.0 SLM application, it showed extra blue color log.

2. For Quick Start SLM, it didn't.

So, how to do to remove the logs?

Hi,

I have tested the SLM sample in NCS v2.7.0 and after building with sysbuild in VS Code I got only "Ready" as a response. You could try to clean up your terminal before restarting the nrf9151-dk board.

Hi Dejan

When shall we build with sysbuild? And, when shall we build with no sysbuild?

With sysbuild, it did remove the logs at booting.

Hi Jeffery,

Here is what NCS v2.7.0 Release Notes webpage states in its Highlights: "All samples and applications in the SDK are built with sysbuild by default. Applications that are outside the SDK are not built with sysbuild by default."

Hi Dejan

Did SLM application belong to SDK?

If yes, building with "Build system default" is same as building with "Used sysbuild". Right?

As you mentioned, default is sysbuild.

How come log message except "Ready" shown up if checking "Build system default"?

Hi,

I have reproduced this behavior. This might be related to the place where your application resides. You could try to build SLM sample in NCS v2.7.0 using VS Code and "Build system default" when your application is located inside NCS and when it is located (copied) outside of the NCS. Is there any difference in the output in these 2 cases?

Hi Dejan

You are right. 

In VS code, "Open an existing sample" to SLM application inside ncs2.7.0. Then, build with system default.

=>

Only "Ready".

As I tested before, "Create a new sample" to copy SLM application to outside folder of ncs2.7.0. Then, build with system default.

=>

Booting logs + "Ready"
