RMB sentence shows wrong waypoint name was created by dwarning
Hello,
I found a problem with the qtVlm (V.: 5.10- generated RMB sentence. The place for starting and destination waypoint name is mistaken:
$GPRMB,A,0.00,R,myBoat,POI12,5226.124,N,01340.598,E,3.4,133.2,0.0,V,A*3E
Here myBoat is the starting place and POI12 the first waypoint, or destination.
From standard:RMB - Recommended Minimum Navigation Information 14
1 2 3 4 5 6 7 8 9 10 11 12 13|
| | | | | | | | | | | | | |
$--RMB,A,x.x,a,c--c,c--c,llll.ll,a,yyyyy.yy,a,x.x,x.x,x.x,A*hh<CR><LF> Field Number:
1) Status, V = Navigation receiver warning
2) Cross Track error - nautical miles
3) Direction to Steer, Left or Right
4) TO Waypoint ID
5) FROM Waypoint IDCan you comment please.
Thank you

Hi,
I remember I have been there already and I think qtVlm is right. There are on the net some documentation that are wrong.
Please check opencpn.org/wiki/dokuwiki/doku.php?id=op...tures:nmea_sentences or campar.in.tum.de/twiki/pub/Chair/NaviGpsDemon/nmea.html#RMB or . gpsd.gitlab.io/gpsd/NMEA.html#_rmb_recom...vigation_information and many other that are stating that 4 is "from" and 5 is "destination"

Interesting! I mean From -> To would be the normal human thinking. But things are different.
This is my link:
www.nmea.de/nmea0183datensaetze.html#rmb
And now openCPN 5.6.2 under Ubuntu:
<BLUE>--> 20:37:32 (TCP:10.1.1.1:10110) $ECRMB,A,0.000,R,002,001,5226.177,N,01340.350,E,3.248,134.405,-0.196,V,A*4C
You see it is vice versa the openCPN documentation. Can you check it.
Made an check with avNav too which also gave To -> From.

The documentation you are using is wrong. As I said I have been trapped already. The correct sentence is 4 = from and 5 = to
