Its really important to have that information, and I would really appreciate the information being put back on.

Also I change my boat name, depending on the circumstances, to include "Solo Sailor" to help with safety (at night, etc). I cant tell if the name change is being transmitted without OpenCpn. The software for the AIS doesnt confirm the transmition properly like OpenCpn was doing.

It was a very useful detail on OpenCpn and I used it every time I turn the computer on... To give an idea of that, below is a screenshot of a day at sea and the tracks show when I have the computer on. given I check AIS each time its on, thats about 24 times per day I will be missing vital information.

Dave wrote the code.
He knows what he is talking about.
Read his post again!
What you want back, was all the time, just an illusion.

Thomas,

one issue for Mark was the above one: using ownship AIS listed to control the settings done.
This does not mean of course that any message has been sent over the antenna.......
Listing the own AIS wouldn't make harm - as no alarm is triggered.

Hello Dave,

I am busy on my side to try to explain in my tutorial how to do it to send a route or waypoint to a GPS or autopilot with O.

Not having on hand the right hardware for testing, I have to take the info that drags on the cruisers forum. Not always easy to follow. On a beta version to another, there is always here and the small changes.

There is an item that bothers me in the language file. This is the item "Send to GPS" which appears several times as an alternative to "Send to GPS ...". Obviously, we have translated "Envoyer au GPS" or "Envoyer au GPS ...".

But there is something wrong in it. For example, on my side, on my boat, I do not want to send to GPS. I want to send to the autopilot. Other users have similar problems.

In your opinion, can we go further, and simply translate the language file, with "Envoyer" or "Envoyer ..." ? Without the world "GPS".

B.R. Gilletarom.

Gilletarom....

There is perhaps a difference of terminology here.

One does not normally send an entire route or single waypoint to an autopilot. One may send a route to an external GPS, and the GPS may then be commanded to control the autopilot. Or one defines a route in a chart plotter, and that plotter directly controls the autopilot.

Autopilots typically respond to progress updates along an active route, and these updates are usually sent by a GPS, or by OpenCPN.

OpenCPN will send updates and control the autopilot directly if a suitable output connection is defined, the autopilot is connected to that port, and a route is activated.

This is the usual case. There may be some other very smart autopilots that can input a route, and follow it so. Such an autopilot would need an embedded GPS receiver, however...

Am I missing the point?

Hello Dave,

I would have to bang my head against the wall ... But it hurts. I will avoid.

I just read the manual of my autopilot. Why, I did not do it sooner!

Obviously, you're right. Unable to send a road or even just waypoint.

So you're right, leave the item as you did.

But I have another question.

In the manual of the autopilot I found the list of NMEA sentences he uses.

Suppose a boat very well equipped electronic instruments (This is not the case of mine, but that's another story). Using a connection to a port input and / or output, will my OpenCPN to provide autopilot every sentence he may need? And vice versa, will my OpenCPN NMEA sentences using the autopilot issue.

Below is a list of NMEA sentences. I read this list on the SIMRAD manual (TP10/TP22/TP32) page 26:

6.3 NMEA sentences received
The NMEA 0183 information required for full functionality of
the TP22 and TP32 whilst in Nav mode is as follows:
– Cross Track Error
– Bearing to destination waypoint
– Arrival at waypoint indication
– Magnetic variation
– Boat speed
This information is extracted from the following NMEA 0183
sentences:
Received Data
APA Cross Track Error, bearing to/arrival at waypoint
APB Cross Track Error, bearing to/arrival at waypoint
RMA Speed & course over ground & magnetic variation
RMB Cross track error, bearing to/arrival at waypoint (T)
RMC Speed & course over ground & magnetic variation
BWR Bearing to/arrival at waypoint (rhumb line)
BWC Bearing to/arrival at waypoint (great circle)
VHW Boat Speed
XTE Cross Track Error
Note The Cross Track Error (XTE) information has a maximum
value of 1.2 Nautical Miles. If the XTE exceeds this while using
Nav mode, the Tillerpilot will sound an alarm, exit Nav mode
and return to Compass Auto mode.
The Tillerpilot also extracts the apparent wind angle from the
following NMEA 0183 sentences:
Received Data
VWR Apparent Wind Speed & Angle
MWV Apparent Wind Speed & Angle

Thank you in advance for your answer about this long post. I'll obviously need an answer for me to write with less de'erreur possible, a web page on the website that I provide for OpenCPN. Thank you in advance for your detailed response.

Best regards Gilletarom.

...having a nuisance inserting a waypoint in a route. The nuisance is: what if I wanted to insert a waypoint without changing the courseline? it seems near-impossible. I know that waypoints can be moved when the waypoint dialogue is open and that's cool. But when I insert a waypoint the dialogue is not open, and yet the route will be changed....d'you see? examples to follow if wanted but it's easy to try .

added. My waypoints are "locked" in config

[HappySeagull]

here is a similar bug? from Beta 3.1.915
http://www.cruisersforum.com/forums/...ml#post1037338

it was fixed in next beta as per Jespers comment http://www.cruisersforum.com/forums/...ml#post1037910 ?

Hello Dave,

I complete the issue of the previous post. Here is the list of NMEA sentences that the ST1000 and ST2000 at Raymarine :

NMEA cabling
If required, you can connect a NMEA navigator or wind instrument to the tiller
pilot. It can then use this information for Track and WindTrim modes.
Recognized NMEA data
The following table lists the recognized NMEA sentences.
Information NMEA 0183 data
Cross Track Error APB, APA,RMB, XTE, XTR
Bearing to Waypoint APB, BPI, BWR, BWC, BER, BEC, RMB
Distance to Waypoint WDR, WDC, BPI, BWR, BWC, BER, BEC,
RMB
Waypoint Number APA, APB,BPI, BWR, WDR, BWC, WDC,
RMB, BOD, WCV, BER, BEC
Speed Through Water VHW
Apparent Wind Angle and Speed VWR


If I understand correctly, it is NMEA autopilot that is capable of decoding.

Which ones OpenCPN is able to send him?

Thank by advance.

B.R. Gilletarom.

Gilletarom....

On Route activation, OpenCPN sends:

ECRMB
ECRMC
ECAPB

For reference, you may see these three sentences listed in the Connections Output Filter list. They may be individually disabled. My Raytheon Autopilot is happiest with just ECRMB.

Hello Dave,

Ah Dave, I do not know you but I know you well in this post. Too bad, I will do what is possible with a reply as short. And with me, all who write pages for different website defending OpenCPN.

Best regards. Gilletarom
