Hi Pau,

No need to change anything in prj_release.conf, it just disables functions and hardware used for debugging purposes which will help your development. They will not be used for a formally released product.

Best regards,

Charlie

The actual light switch prj_release.conf, I copied the ligth bulb above by error

Hi Charlie,

I am running Toolchain Manager to execute nRF Connect SDK v2.1.1 with Visual Studio Code.

There is a prj_release.conf file indeed that I believe it is used when I build the project configuration with the nRF Connect extension from VSC.

I will try to apply the changes in the configuration file you are mentioning and hopefully this week I will go to the place where I can measure the current and tell you about the results.

May I ask what disabling the RTT does to the build, if it makes the scenario of light-bulb light-switch stop working or simply it reduces the response from the bulb. It may have nothing to do with what I just said so I would like to know surely.

I can also attach my current prj_release.conf without applying the changes just to have the logs.

Hi Pau,

Did you build with prj_release.conf? It has some configurations to disable RTT, log system and so on to save power for formal release products.

Best regards,

Charlie
