Hello, New owner here, just what I discovered a few seconds ago :
the GPS logging format is broken (but not unusable).
First of all the files are named ".gpx" but aren't gpx files at all, they're nmea logs with custom messages. Due to the custom messages (and their lack of CRC), most - if not all - the software dealing with GPS data won't be able to make much sense out of it.
So far I've spotted 2 custom messages :
$GPSCAMTIME 20160817195248
at the beginning of the files, it gives a hint about the date, as all the other messages are only GPRMC, lacking any date information (which is normal for GPRMC messages).
$GPSEVT,N,N_20160817195237_0058_L.jpg
When I press the remote (funny because I get no jpeg when I do so), I have no idea about the signification of those fields (apart from the obvious date and time).
It would be really great that if DDPAI would actually (1) name the file correctly (2) add CRC to their messages (3) document their custom message (4) use standard message and get rid of this nonsense (there are already enough messages format in the NMEA norm)
Have you spotted any other messages in the gps logs yourself ?
