Intercepting log and printf messages

[Deouss]

Is there a way to intercept/queue all logs and printfs to some buffer?
This is to display later on some screen or send over network for diagnostics.

Thanks

So this brings up a question I have been putting off asking.
When looking at the above link, and you see something like

Code: Select all

vprintf_like_t esp_log_set_vprintf(vprintf_like_t func)

What is the next expected step to learn how to use it?
That and others in that section in and of itself is IMHO useless information.

You are searching for the repositories type? You really need to specify "&type=Code" "https://github.com/search?q=esp_log_set ... &type=Code"

When I use that URL , that image i sent is what I get.

You must be signed in to search for code across all public repositories.

But it works for me in private browsing so not sure what to say.

The URL given was:
https://github.com/search?q=esp_log_set ... &type=Code

Signed or not that URL does not work, what did work was this one. Notice the "/espressif/esp-idf" part in the URL link.
