LOG_REPLAY caught my attention while examining the parameters related to logging. After that I set LOG_REPLAY=1 and implemented the instructions in this site https://ardupilot.org/dev/docs/testing-with-replay.html .
A new xxx.BIN file created and it is a little bit different for EKF messages. There are NKF, NKF, NKF, NKF etc. What are these? What should I understand these values? Actually, What are the advantages of LOG_REPLAY?
Thanks for answers!
