Waypoint not received from Garmin GPS

[andrewvik]

Hi, I'm trying to transition from MacENC to OpenCPN 5 on my MacBook Air. I can't figure out the following required feature:

My GPS source is a Garmin 180 or 72 at the helm. OpenCPN receives position data just fine. When I do GOTO WAYPOINT on the Garmin, OpenCPN does not seem to do anything with this information.

With MacENC, upon hitting GOTO WAYPOINT on the Garmin, a little window pops up with the waypoint name, distance, XTE, VMG, etc. And MacENC draws the path on the chart. This just happens automatically - never had to configure a thing.

NMEA headers for the active waypoint seem to be GPBOD, GPRTE, GPWPL.

Anybody with a solution for me?

I've also had zero luck sending waypoints to the Garmin 180 from OpenCPN. MacENC sends multiple waypoints at once without flaw.

Cheers,

I use both 128 and 76 with OpenCPN

These threads may help.

I typically use O for route plotting and then upload to GPS and subsequently goto on the AP. The acquired WP then displays as active on O.

You may need to check "output on this port (for AP or NMEA)" in settings - connections.

There is an issue with early Garmin in way they accept wp / routes.

Tupaia, thanks so much, the first link you mentioned was a great help! I'm now able to upload waypoints with ease, and entire routes (in a clumsy workaround).

But... when I activate a waypoint in the Garmin 76, there is no reaction in OpenCPN. MacENC, and my ST4000+ autopilot receive all of the DTW, XTE, etc. info just fine.

How do you get the WP to display as active in O, as you wrote above?

Cheers!

Hi Andrew,

Although I use both GPS's only the 128 is wired in so not sure if the 'Active WP' works with the 76. In the case of the 128 the 'Active WP' MIGHT only show on OCPN when the AP is actually in TRACK mode and or the GPS is in GOTO mode. I am unable to get to the boat at the moment (CV19) so if the above doesn't solve it here are a couple of things that might help. Can't remember but could be down to 'repeater setting' or feedback signals see below.

1. I seem to 'remember' that there was an issue with the connection setup with OCPN. Play around with these first.

Use Garmin GRMN (Host) mode for uploads - NOT Checked
Use Garmin (GRMN) mode for input - NOT Checked
Output on this port (as autopilot or NMEA repeater) - IS Checked

2. My ST5000 (this is the same as ST4000 with different firmware) is connected through Raymarine e85001 interface and there are several ways of wiring the PC/AP/GPS to this.
