AvNav - navigation in the browser

[Kukel]

Thank you, the alarm sound is not the priority for me, activation of the waypoint is much more important. I'll have to wait for the release though, so it will take some time before I can try out the changes.

Yet another question:

I tried to create two new routes for later use, but there seems to be no way to save route #1 and then edit route #2. In Edit New, only existing routes can be chosen, no new ones created.
I exited AvNav after creating the first route and restarted to create no. 2 as a workaround, but I think this could be made easier.

Hmm, was still a bit tricky.
The latest daily already has some improvements...
When you click at the route display in route editing mode you get a dialog.
Just change the name of the route to a new one and click "Copy".
You can also empty the route before clicking on copy...

The new version will have a clearer dialog with "save as".

I am running signal k behind ssl. Is there a description of integration of signal k behind ssl or is it straightforward? Is there a also description of what needs to be done for running avnav itself behind ssl?

[wellenvogel02]

Not sure what exactly you want to know.
Out of the box there is no description for running AvNav behind SSL.
I'm not really sure what the use case would be.
AvNav is not hardened at all - so I would never recommend to expose it to some untrusted network.
In principle you could set up a proxy e.g. using lighttpd.
I guess it will work for most cases - but for sure not for all.
At the end you will always have to struggle with the certificates - either use some really trusted ones - like let's encrypt (requires net connection) - or install some CA certificate on all clients.

There are a number of reasons:
Browsers will be blocking http more in the future.
We're building a docker based platform where the apps on the boat are available through a portal. Its easier to use (and to integrate) if all applications support https.
Third reason is that we make the applications available at home through tunnels which is also best if all traffic is https.

Anyway, we'll try it and see what comes up. Any pointers are welcome.

I created an issue in github for the connection to signalk behind ssl.
When put avnav behind https, the first thing we notice is that the ochart en updater plugins don't work. Is that something worth investigating?

[wellenvogel02]

There is a new Version available for AvNav - see the release docs.
A couple of new functions and especially:
Adaptations to the new o-charts shop.

Any comments / suggestions / bug reports are welcome.

Hi, I have updated to the newest version today, and I have a few questions:

-i run AvNav on the same system as OpenCPN (on a raspberry pi) and I want to use the o-charts maps that I use in OpenCPN. OpenCPN (including o-charts plugin ) updated to latest version. I checked the checkbox for the OpenCPN Charts in AvNav settings. However, it didn't work. I entered chartpad in the XML file, boy still didn't work. The OpenCPN config file is in the right place.


-also, when trying to start AvNav on the RPi itself, I only got an error message in the browser. (Chrome) The same happened when manually entering the AvNav IP address and port.
-finally, AvNav gives me an error message about an error in the config file, something about a wrong character used.

[wellenvogel02]

I think we have to split things up....
(1) I guess you missed to check the release notes. You need to install avnav-ocharts to utilize the new o-chart formats - and you currently don't have it. Easily can be done with the avnav update plugin
(2) Not sure what you changed in the config but the status page gives some hints on where the error is located.
I recommend using the editor in the avnav update plugin as this is already doing basic syntax checking. But there should be no need to do this.
Anyway AvNav did a fallback to the last working config file....
(3) for the last part it's not really clear what did not work when trying to access AvNav from the browser.
So it would be helpful go explain this in more detail.

[Kukel]

Thanks for the quick reply, it seems all is solved.
-i installed the O-charts plugin on AvNav
-I reinstalled the o-charts map in OpenCPN (apparently, something went wrong there because OpenCPN doesn't properly close when you turn off the RPi with OpenCPN running, you have to close it separately first).
That did the trick for the map.

Problem nr 2 somehow solved itself.

Problem nr 3 has to do with chromium. Somehow it won't open any page, including the Chromium Settings page... Very weird, but nothing to do with AvNav.

[wellenvogel02]

Ok, great to here that it works...

I was fiddling a bit with the depth coloring settings, and I saw nothing change in the map. (I am using OpenCPN's o-charts maps in AvNav). Then I changed something in the OpenCPN depth coloring settings, and the colors changed in AvNav as well. Am I right that the depth coloring in AvNav is the same as in OpenCPN if I use OpenCPN's maps?

[wellenvogel02]

Not sure what exactly you did.
If you play with the color definition files, AvNav will not immediately detect that Something changed - so the caches will remain valid with the old colors.
Just do an arbitrary change on the settings page and save this.
This will invalidate the caches an the new color values will become visible.
AvNav does not use the OpenCPN color settings.

I really like what you've done with AvNav. Keep up the good work.

If I'm bored when I retire I'll join your effort.
