generate log file

Postby kishan patel » Fri May 25, 2018 5:37 am

Hello,
We can see all debug print on monitor screen by using "make monitor" command. Now i want to save all that logs in one file. Is it possible means how can generate log file to debug purpose?

Thanks and Regards,
Kishan Patel.

My notes seem to say that all debug/logging is written by calling the function that is registered with the esp_log_set_vprintf() ESP-IDF function. By default this writes to serial but looks like it could be used to write to an arbitrary location.

If you are running on windows then use Teraterm and open a log file. Doesn't get any easier than that.

You can always create a file system on the flash and save it like a normal file. But that will require another block of code to transfer it to a host. Which could be simply reading the file, printing it, and capturing it with Teraterm.

Log files can grow rapidly and take precious flash space. One option is to log in separate log partition or better attach an external SD card which can be read faster in a pc.
