How to see LOG_INF, LOG_WRN messages, preferably in real time

[DiBosco]

Al over these example programs there are all these messages like

LOG_INF("Filters matched. Address: %s connectable: %d",

addr, connectable);

How do you actually *see* them? The best bet would be have them spit out over the USB

connection that's

used for the built in debugger. I've seen some pages suggesting this might be true,

but I just can't

understand what any of them are saying.

I've seen this for example:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.4.99-dev1/kconfig/CONFIG_LOG_DEFAULT_LEVEL.html

And it casually says things like this:

At <nRF>/samples/Kconfig:33

Included via <Zephyr>/Kconfig:8 → <Zephyr>/Kconfig.zephyr:9 → <BuildDir>/Kconfig/Kconfig.modules:1 → <nRF>/Kconfig.nrf:24

Menu path: (Top) → Modules → Nordic nRF Connect

I have absolutely no idea what this is saying.

Are there some explicit instructions somewhere that says:

You need open this menu up from this part of VSC, click here, go to sub

menus X, Y & Z to this line and change it say

DEBUGGING_OUT_OF_JLINK=y

Or whatever it should be.

All I want to see is what these messages are saying in real time. With any normal

debugging system

I'd set a breakpoint and single step though looking at registers to see

what's going on. Or in extreme cases use

a UART to spit out some info, but I'm already using the UART to

[try to] send info in and out over BLE.

Hi!

The nRF52840 has 2 UARTE instances, so you can use one for logging and the other your application.

Thanks, but that doesn't really help in terms of how you'd assign it, set it up, point the debugging info/LOG messages etc to the different UART  and it doesn't address whether it's possible with minimal effort with the segger interface.

How do you actually *see* them?

If you are already using a sample that uses LOG messages, and looking for a tool that sees the logs, then I suggest either:

1) If you are using VS Code, we have the nRF terminal:

https://marketplace.visualstudio.com/items?itemName=nordic-semiconductor.nrf-terminal

2) You could also use our Serial Terminal app:

https://docs.nordicsemi.com/bundle/nrf-connect-serial-terminal/page/index.html

I do have the extension pack installed, but there's no nrf terminal available. There's nrf  serial  terminal and nrf debug.

Sorry to mither, but any chance of a reply on this please?
