BB Logging - Missing Data ?

[CV8IIM6]

Here is another similar problem I'm having whilst recording a BBL to SD.

When I start recording the time, frame count and all PID data displayed on the V2 looks good and appears to save. But, when i upload it to the computer whether it's a 10 minute log or a 2 hour log all i get is this (refer attached). No data just notes dropped each frame?

I've recently noticed that the blue light on the V2 does not flash when this fault occurs. I just stop recording then immediately start again and everything's ok for about another 6 BBL's so it's easy to work around but would be nice to know what's going on. I format regularly and have tried 2 brand new SD cards. I'll try recording to internal memory instead for a while to see if that helps.

The "log full of notes" problem has been noted before. Generally it's due to an existing application using a particular screen function that is incompatible with ScanTool. For example, VNC Viewer will cause this problem. The fix is to shut down applications one at a time and restart ScanTool to see which one is causing the corruption. If all else fails.... reboot.

thanks for the reply swingtan, good to know i'm not the only one to experience the log of notes. i think the problem is BBL/V2 related and nothing to do with ScanTool and other applications running on the laptop as every time it happens the file viewed in EFILive Explorer is only 2KB (when it should be between 2,400KB and 8,800KB for the distance traveled) and no VIN is stored.

i can close every application down one at a time, use a different computer and re-boot as many times as i like, the file will still look the same.

A 2KB file is about the right size for the file header ( 1024 bytes ) and the metadata only. 2KB would probably have little or no real data in there at all. I've had this once or twice and the usual reasons were....

• I'd filled the SD card and there was only enough room to write the file header.
• The ODBII cable connection was interrupted mid log, causing the V2 to abort writing data.
• The SD card was removed from the V2 before canceling the logging operation.
• The SD card suffered a connection loss during the logging process.

There have been one or 2 rare occasions where I have corrupted a file like this by turning off the ignition before stopping a log. But that was a couple of firmware revisions back and I haven't been able to replicate that. So I think it may have been an SD card issue. I've since swapped from using a 2GB card to a 32MB card and found it to be more stable. Perhaps the use of bigger cards may take up more resources and cause an issue?

I think you might be onto something there Simon. Always a wealth of information. ....

Can you please send me some samples of the 2K log files?

Hi Paul,

I attached one of the files in post #19 of this thread.
I never saved any other log files but I could get more within a week or 2 if required.

Cheers.
