The Mac processor and I/O is a little bit faster than the little esp32.

You can try to set to 20000 then reboot. Should be about 5 times faster than default. But if running old hardware without 5v usb connected, then may crash. Recent modules, or when you have USB connected, can operate at high speed.

Now i remove the SD card in my Mac the speed is 10MB/s / 80MB /s (W/R).
I have a 1.5 year old modell with the following numbers (2018020219PTWU)
If run ‘config list sdcard’ only show 'sdcard (readable writeable)'
if i run 'config set sdcard maxfreq.khz 16000' now show this value for ‘config list sdcard’.

For download, if i copy the log to another folder than sd root, i can browse the folder tree, and download directly.

Tamás,

Yes, it seems SD CARD is too slow.

Can you check ‘config list sdcard’ and see if you have a ‘maxfreq.khz’ value set? The default is 16000.

If you have a reasonably modern OVMS module, or are running from USB power (even if 12v is connected as well), you can set:

config set sdcard maxfreq.khz 20000

and reboot, to improve the SD CARD write speed.

The 1R11 means reception of a 11bit (standard) CAN message on CAN1 bus. A 1T11 would mean transmission. I think you should be able to download via the browser - personally, I just scp the files off the module over wifi.

Regards, Mark.

I want to create log file from can messages while Lexia connected to obd, but many message has dropped. My sd card is too slow to write all data?

I start logging with can log crtd /sd/lexia.crtd command

Closing log: Type:crtd; Path:'/sd/lexia.crtd'; Filter:off; Vehicle:MI;

Statistics: total messages: 3334194, dropped: 2707476 = 81.2%


In can log i can see the incoming messages?
This is a RX message:
175594.785 1R11 346 27 10 40 00 00 00 00 42
if 1R11 is 1T11 this is a TX message on CAN1?
How can i download the log file, the easiest way, because if i use browser and add the file url (ip/lexia.crtd) the browser load its content.
