AvNav - navigation in the browser

[wellenvogel02]

Ohhh - yes, can reproduce this.
Will have a look tomorrow. Most probably an easy fix.
Maybe as an intermediate solution you could try to edit the layer on a desktop browser if you could connect one...

No PC present on board, unfortunately. I'll wait for a fix.
Other question (follow-up question actually): in settings/route i can set the Approach distance, and at the specified distance, the bell alarm sounds. However, the waypoint is not "ticked off", and the next waypoint doesn't get activated yet. This only happens a lot later, usually when I've already gone past the waypoint. Is this supposed to happen? To me, it would make sense if the next waypoint is activated as soon as the approach distance is reached and the alarm sounds.

I'm sailing these days, so more things come up every day...
-I couldn't find this, but is it possible to change the color of the buttons in night mode? They are a bit too bright for me, compared to the map.
-Can I have a visible scale on the map display?

[wellenvogel02]

Ok, some answers:
1. for the dialogs: I just started a daily build with a correction. Maybe you would like to try it out.
2. for the buttons in night mode: You can always tune things with some CSS - e.g. setting opacity - see the user css doc
3. for the next waypoint: yes, intended behavior. It will skip to the next once the distance to the current target gets bigger and the distance to the next target gets smaller. The alarm should give you an "early hint" that things will (potentially) become interesting now. If you feel you would like a different behavior - just file an issue on GitHub - should not bee too complex to be implemented.

I'd like to try out the daily, but I don't know how to install it. I'm on a sailing trip and I only have my RPi, phone and an Android tablet present.
For the same reason, I wouldn't know how to edit the night button color with CSS now, seems a bit complicated for me.
I'll see if I can enter a GitHub request for the waypoint handling when home.
How about a visible scale on the map?

[wellenvogel02]

For the scale:
Maybe just alsoa GitHub issue - will help to not forget about...

Installing a daily will require some command line access. So it would be possible with the tablet and an ssh app on it - but maybe rather inconvinient.
For the buttons I will just prepare something that you could copy and paste - editing the user.css is possible on your phone/tablet.

[wellenvogel02]

For the buttons you could add to your user.css:

.nightMode .buttonContainer .button {
    opacity: 0.5;
}

Just use the edit function on download page/user tab at the user.css.
Do not forget to reload the app (web page). Sometimes mobiles devices cache css - so maybe try it with another device.

[Kukel]

Thanks, that was easy to do. I'll let you know if it works OK.

In the meantime, i think I have encountered another new issue:
When navigating along a route with the screen off (i use a headless RPi with an Android tablet, chrome browser), sometimes no alarm is sounded when i am near a waypoint. Also, a new waypoint never gets activated.
If i turn on the screen after i have passed the point where the alarm should have sounded, the alarm sounds as soon as screen turns on, and a new waypoint is activated shortly after.
If i don't turn on the screen, however, i keep being pointed to the waypoint that i have already passed.
I like to be able to sail with the screen off to save battery, but that's not possible right now.

[wellenvogel02]

For the alarm sound:
Which kind if sound device do you have connected to the pi?
For the switching part I will check....

[Kukel]

The alarm sound comes from the Android tablet that i use as display.

[wellenvogel02]

Ok, so how do you switch off the screen?
Not sure if chrome would do anything (like playing a sound or communicating) while in standby.
And how do you see that you are still pointed to the old waypoint with the screen being off?
For sure it could take some seconds for a device when coming from standby to fetch the newest route and waypoint info.
Maybe you could go for BonjourBrowser on the android tablet and enable all it's features (including it's internal browser).
This will e.g. give you a dim button in AvNav just dimmung the screen for power saving but still running everything. And with one touch it will get you back to normal operation.

[wellenvogel02]

Ok, could reproduce half of the issue:
Switching to the next WP does not work.

But the waypoint alarm on the server should work.
see https://github.com/wellenvogel/avnav/issues/157.
Daily with a correction is just building.

[Kukel]

I switch off the screen just by short pressing the on/off button on the tablet.
I should point out that i have a Nasa Clipper GPS repeater connected to the RPi that shows me bearing/distance to waypoint, COG and SOG, so that's how i see that something goes wrong when passing a waypoint. I usually only turn on the tablet to steer around shallow areas.
I will install Bonjour Browser, see what that does.

[wellenvogel02]

Ok,
As mentioned:
The next waypoint issue is corrected in the daily version, a release will need some time.
The alarm will only be available on your tablet if it is not in standby.
So either Dim mode in BonjourBrowser or an audio device at the pi.
