Hi, very sorry for the wait

I believe the best way to do this would be to disable CONFIG_LOG_BACKEND_RTT, and create your own backend using your functions and LOG_BACKEND_DEFINE()

To see how this is done, read the Backends section of the documentation:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/services/logging/index.html#logging-backends

You might also find it useful to have a look at how the existing backends are implemented:

Hi,

Do you mean the log from the application or the log from the entire system? ie. every enabled call to LOG_INF(), LOG_ERR() etc. Do you want calls to printk() to also be included?
