OpenCPN for Android Beta test 4.1.530

[HappySeagull]

Two problems (Xperia Z3 compact A5.0.2)
1) Newly created and imported route doesn't appear in route manager. Need to exit from O and
start to see it in RM

I have seen this happen now too. ..even a crash or two can be caused by looking for the new route "too soon" in RM . O seems to need to find the "spare time " from other tasks to incorporate it there?

Lines between wpts are there now too

The Xoom MZ601 3G has a BCM4750 IUBG AGPS chip.

The GPS works independent of networks, and is operating properly. If not, how could I have used the tablet GPS in the middle of an ocean hundreds of miles from the nearest wireless or network tower?

I researched this issue of usability with OpenCPN over three years ago and discovered there are two types of output by android GPS chips. Position or nmea. I can't find the source of this information at the moment, but at the time emailed Motorola asking which type of data output was produced by the Xoom. The answer was unequivocal, position. OpenCPN requires nmea data and the only solution I've found to date that permits using GPS 'positional' data with OpenCPN is the android app GPS Share WIFI. So, unless OpenCPN incorporates a method for using or converting 'position', lat/long data to nmea internally, people with chips that do not produce nmea data will have to use the android app GPS Share WIFI. Just the way it is...

This chip is also used on the iphone. Found this:

Question: "I am looking for a way to get NMEA data from the builtin gps receiver of a iPhone. Is there a way to access this data without using CLLocationFramework?"

Answer: "I don't see why you wouldn't be able to forge your own $GPGGA sentence based in information that can be retrieved from CLLocationFramework. Obviously you won't be able to set then number of satellites and HDOPs value will be approximated. If you must have NMEA0183 sentences, you could create them yourself."

Greek to me, but may provide a clue to someone who understands how this can be worked into OpenCPN.

I too, found the toolbar buttons a bit small on the LG 8.3 tablet. Above reference for 'sliders'. Can someone explain please?

Many thanks and thank you for this implementation, I can now use one app for all navigation needs.

Thanks, was on the way to post about it after discovering it myself. Great app!

Have just downloaded on a samsung tab 4

Is ais on network feed disabled, as on ais target list ships names show , but not their positions so they are not clickable on center view, however basic name is shown from target info. own ship gps position is carried across though.

selected all sentences
Or more likely it is something I missing in the stream.

We are receiving the complete AIS data stream via Wifi perfectly.

Do you have another system - normal PC - to double-check?

Without this slider, I could not use the toolbar that was ridiculously small. It was also impossible to zoom with two fingers.
With this slider, set up completely at right, it's OK.

There is a second slider. I'm pushing the right or left, it changes nothing. In all cases, buoys and other marks are ridiculously small.

I could create a mark, create a route. I could create the route name, export the route. But I could not change the line width of the route.

I was able to measure a distance.

As the GPS my tablet does not work, can not be used with OpenCPN. I think qu'OpenCPN nothing to do.
I tried to put my GPS ND 100, GlobalSat product, in the USB port on my tablet, GPS is not seen. Can not create a connection.
I tried to put in the same port USB GPS data coming out of my VHF 550 AIS RT, it is useless. Unable to establish a connection.

Best regards. Gilletarom.

Will dig it out later & re read the networking instructions!

Thanks for your help, it is not the easy answer!

[bcn]

What I wanted to express is that the settings are the same as for any other device.
When it works with your PC the same setting for Ethernet/Wifi should work for Android.

Hello Dave,

During my trial creation of a road, that is not immediately appeared in the road manager.

Contrary to what was said in this thread, another intervener it is not necessary to stop and restart the O.

Strangely, I found tracks dating from previous trials (????).

I have deleted and then the route appeared in the route manager !!!!

Best regards. Gilletarom.

Installed on a tiny Samsung GT-S7710 phone with 4' diplay.

Installs fine.

Internal GPS works "out of the box"
CM93 charts installed at /mnt/extSdCard/maps

This phone is a very low spec phone so I'm impressed that Opencpn will run on this entry level phone. ( but it's waterthight)

from an Acer z220 Android 5.0.0
can confirm Ptizef's 2) no track written in route manager ( http://www.cruisersforum.com/forums/...ml#post1837408 )
but tracking works...

However while testing that, this display oddity not seen before(you will have to make it bigger!)


O continued to function

note also another new but more common display oddity in the above: the change to black in chartbar may appear whenever charts are changed via chart bar, not just in the above instance. (per above screenshot, I thought "is this A raster issue or a vector issue?" and attempted to change to vector but it did not fix)

Also, in case it's useful
Here is a log , but it is not from the moment of the above. It is merely a crash from a bit later. Entries are typical per open gl and read-only issues(?)opencpn06-01.log.doc

Happy...

The black chart bar is by intention. It gives immediate feedback that a touch on the chart bar is bringing up a new chart. The chart itself may take a second or two to load...

Maybe it should be grey, or some other less morbid colour?

The odd, fuzzy chart display is new, though. Do you see this often?

Thanks
Dave
