Continuous logging not working on Crazyflie with micro SD card deck

[amitx64]

Description:
When using the micro SD card deck with the Crazyflie, I encountered an issue with continuous logging. Initially, upon connecting the Crazyflie with the cfclient, the micro SD card was detected, and successfully mounted. However, despite the console indicating that the configuration file was read successfully and logging was enabled (usd: Logging to: log00), no data was being logged to the file.

Upon deleting the log file and reconnecting the Crazyflie with the cfclient, I noticed that logging only occurred after updating the usd.logging parameter to zero, effectively stopping and restarting logging. This raises the question of why continuous logging does not occur without stopping logging first.

Expected behavior:
Continuous logging should occur without the need to stop logging first and restart it.

Actual behavior:
Continuous logging does not occur unless logging is stopped and restarted.

I think the problem is that the "file closing" is not written to the sdcard if usd.logging is not set to 0 to stop it. I think this also should happen when powering down though, so you might have found a bug.

@tobbeanton Actually, my aim is to log data during flight. This way, I can analyze the data after the flight if the drone behaves unexpectedly.

I've created an issue so we can investigate the problem. Workaround is to manually stop the logging using the usd.logging variable.

Hi, did you solve it ? I encounter same problem. No data in the log file ~

Hi!

I answered in this thread as well.
Please come back if the workaround mentioned here does not work for you.

The issue is not resolved yet.

@CalvinKoung Not solved yet!

Or how can I store the plotter data ?
