Timeout means, no answer from the Flight Controller to the LOG_REQUEST Mavlink command.
0. Check if there are any other mavlink devices connected, and make sure that the flight controller is selected in the connection dropdown.
check if there are any logs on the SD card and they are readable (remove SD card and check)
Check if USB cable.
Use MavFTP to download log files (it is much quicker than the Mavlink Download)
the Cube has been enclosed, It is difficult to access. Downloading a 3.3MB log took hours.
Is there a way to speed it up? connected via the USB port on the carrier board.
[Edit]
No, it seems how quickly I do a USB connection from the window MP to the FCU, go to the Dataflash Logs tab, and start to do a Download Selected Logs. if I slow down the steps using the same USB port, multiple log files can download very fast.
