The “log” command can be used for temporary changes, if you change the configuration, it will
be applied as a whole, replacing your temporary setup.
If a maximum file size >0 is configured, the file will be closed and archived when the size is
reached. The archive name consists of the log file name with added suffix of the timestamp, i.e.
“/sd/logs/log.20180421-140356”. Using a logs directory will keep all your archived logs
accessible at one place.
Take care not to remove an SD card while logging to it is active (or any running file access). The
log file should still be consistent, as it is synchronized after every write, but the SD file system
currently cannot cope with SD removal with open files. You will need to reboot the module. To
avoid this, always use the “Close” button or the “log close” command before removing the SD
card.
You don’t need to re-enable logging to an SD path after insertion, the module will watch for the
mount event and automatically start logging to it.
