The reality is, if you're not an software engineer (which I'm not) chances are the data will not be usable "as is" ! The explanations for the ID filter are gibberish to me. The news functions from the last firmware could have improved slightly my experience, but sadly I bought mine in 2017 and I have no idea how to update the firmware (if that is even possible).
It would be so much better if we could set filters to get post-processed data instead of just the raw values. That would make it match the description of "simple logger" to me. Right now it more a "basic logger".
Nicely built CAN logger with excellent support. Make sure your SD card has a msdos (standard) partition table, not GPT. No problems logging at 500kbit/s @ ~35% (canbusload can0@500000) to a Class 10 SD card.
