Rolf Stefani replied to Dan Gray's discussion APM Log Visualizer Source Code"Hello Dan,
Interesting software. I see that the app only works on .log and not .tlog files. Are they different formats?
What I was wondering was if the logs look the same as mavlink messages? I have tried to decode the gps…"
Andrew Fernie replied to Dan Gray's discussion APM Log Visualizer Source Code"The format of some of the parameter packets has changed - for me it was the NTUN and CTUN lines. Everything else worked fine for me with 2.8.1 using version 1.34.
I have made the necessary mods and sent Dan a message telling him where he can pick…"

Dan Gray replied to Knut Graf's discussion Could use log analysis help."Hi Knut,
I looked at your log file, and I think I have a couple of clues.
Whenever you went to RTL, it looks like the copter started returning in every case, but the last time it did something interesting.
One explanation would be that you put some…"
Dan Gray replied to Silvio's discussion Free fall from 600 Meters"Hi Silvio,
It looks like the APM rebooted.
There's 5 minutes missing from the GPS log, plus a lot of stuff that looks like a re-boot, right during your crash.
It would be good if you could turn on your motors for logging, it's easier to…"
