So apparently it's better just to send straight signalk strings..

So, I realize this is more of a signalk thing but I feel I'm so far over my head any info is useful - so does openplotter just push whatever it sees on the nmea comm ports to signalk or is it just nmea sentences with a good checksum?
I'm assuming that's where signalK gets the com port data from.
Any tips how I can survive this rapid JSON learning curve are most grateful

At this moment OpenPlotter just converts all the NMEA data from the main and multiplexed stream into signalk. When signalk development is done we will give to sensors the option to create either NMEA or signalk and we will add tools for multiplexing signalk sources. So, if you want to work with OpenPlotter I recommend you to do the opposite, create NMEA data and let openplotter to convert into signalk. Creating NMEA you will have wind data in opencpn, trigger/action system, signalk panel instrument... but creating signalk data you will have just signalk panel instrument.

To be honest I can not help you with JSON because I am not an expert. Signalk still needs a lot of work and the documentation at this moment is really confusing, I know they are working hard. I am waiting for signalk to be done to start that battle.

OpenPlotter don't. OpenCPN I think so but I am not sure.

Yes
/home/pi/.config/openplotter/sensors_b.py

I use VDRplayer to test many Opencpn plugins. I've set up the plugin Launcher with 4 or five different test files to provide easy access to VDRplayer with the different files and settings.

Thanks. The problem I'm hitting with using NMEA 0183 is not having sentences for the likes of battery voltage and engine temperature.
SignalK doesn't seem to recognize XDR. It would be great to have the signalk instrument panel display these on a tablet.
I know nearly nothing about nmea 2000 - could an arduino transmit a NMEA2000 PGN down serial to openplotter?
Thanks anyway, I shall persevere and at the very least hopefully learn something

I am afraid not. They are completely different interfaces and you will need always an expensive converter.

There is a better way to access winlink with ARM Linux using BPQ and a a Mail client.

Here is the downloads page for BPQ:
BPQ32/LinBPQ Download Links

On there you can find the executables for windoze and Raspberry Pi.

Here are the instructions for installing on the Rpi:
Notes on installing and running LINBPQ

Note that there are differences for auto-starting on Debian Jesse vs. Wheezy.

Here are some notes on the installation process, including links to a configuration file.
Amateur Radio Station AG6QO - Notes on Installing pilinbpq

You can download this as a place to start if you like.
It's got more ports and capabilities than you'll need. More than likely you'll need only two ports, the PACTOR one and the Telnet one (you'll need telnet if you want to do control/configuration over your LAN). Also got an AXIP port, two 2m AX25 ports, and one 1.25m AX25 port.

You can also find some notes on the main configuration screens here:
BPQ SYSOP Notes - AG6QO

BPQ seems overly complicated, and only mentions KissTNC.

Will it give me access to WinLink2000 using an SCS PTC ?

That is really all I want, the functionality of AIRMAIL running on ARM.

Right now I have an X86 laptop running Navagatrix that I use for Winlink, and as a backup to my ARM based ships computer.
The ARM based ships computer is always on while underway (screen mostly off).
I would like to relegate the laptop to backup for Winlink as well, and put it in deep storage.

Is anyone else looking for this functionality ?

Cheers,
JM.

Now is a little complicated to setup, but does provide full access to winlink2k. What needs to happen is to add this to the image with a mail front end that provides a settings page and ice pack hf propagation tools like sail mail has and document the setup. I have a pastor II modem and it will work with it or any tnc apparently or the signaling sound card.

Why is BPQ better than the PacLink Unix software recommended by airmail ?

Do you have BPQ working ?

Can you give step by step instructions ?

Thanks,
JM.

Paclink Linux has not been worked on for quite a while. BPQ is being used by Hans for bulletin boards regularly and definitely works on arm and is supported by winlink.

Thanks. The file was not in this directory. Just created the file and changed it. After executing I got the sentence that I want.

After reboot the scripts is not executed. What is the correct way to start this script when booting the PI?

If the file was not there you are running a really old version of openplotter. Try to download and update the last release and all will work right.

I updated it last week already.

When I check the help in openplotter it has version 0.6.0. That is the latest version right?

Just tried again an update, but after that the file is still not in the directory. These files are available:

1w.py fine_cal.py message.py README.md wifi_drivers
calculate.py graph.py monitoring.py sounds wifi_server.py
classes i2c.py openplotter.conf startup.py
connection.py imu openplotter.ico time_gps.py
ctrl_actions.py LICENSE openplotter.py waterfall.py
docs locale output.py weather_log.csv

Yes it is. What a strange thing. That file should be there.
To be sure you have all the files connect to internet and type:

cd 
cd .config 
rm -rf openplotter/ 
git clone https://github.com/sailoog/openplotter.git

Then do your modifications again, enable the checkbox that you will found in the "1W" tab and the script should start at startup.

Ops! you are updating with the development version

Follow the steps in my last post to update with the stable version.
