Openbk7231t: Console Log Output to a File on LittleFS in Embedded Systems

Is it possible to write the console (debug) log to a file on the LittleFS (persistent logging)?
AI: Which firmware or software environment are you using with the OpenBK7231T (e.g., OpenBeken, official SDK, or something else)?
OpenBK7231T
AI: Are you looking to redirect all console/debug output automatically to a file, or do you have a specific logging function or library in use?
I want to write all console/debug output to a file automatically.

Well, how big log file would you like to have? LittleFS is a bit limited in size, so even if we tried to store log in the LFS, it would just store few latest messages... Maybe I could try to create such modification for you, but I'm not sure if it would be feasible for your application.

I want to debug why some of my devices (bl602) go offline (My AP shows them as online. So wifi module is working but I guess the http server is not working anymore.) and come back or do a restart via watchdog. I guess it has something to do with "PowerSave". But for now I just wrote a Script to collect all log via "http://xxx.xxx.xxx.xxx/lograw". Maybe this gives already some informations.

I also measured the difference of the "Current" with and without "PowerSave" and it seems not much (about 1 mA). Is this a reasonable value? Is PowerSave meaningful for a device like this (https://www.elektroda.com/rtvforum/topic4020634.html) ?

What exactly is the difference between "PowerSave" and "DeepSleep"? The latter is not implemented for bl602 devices, right?

Do they reboot while using MQTT, or are you not using MQTT?

DeepSleep basically turns device off until given time passes or until an event on GPIO occurs (like a button press).

Which OBK version? We recently had BL602 SDK update.

I am aware of the SDK update (I was part of the discussion on GitHub) and I am using version 1.18.98 with the following startupCommand:


I am also using MQTT. Yesterday I changed the MQTT host from DNS name to IP to exclude DNS resolve problems.
Does MQTT trigger watchdog reboots?
