  Can not set time from NMEA
Posted by: s99kalle - Yesterday, 02:05 AM - Forum: How do I...? - Replies (2)

I have set up a Rasberry Pi 3 with OpenPlotter and a Garmin 128 GPS connected with a serial to USB converter. It works quite well and i get NMEA data to OpenCPN but there are some problems, one of them beeing setting the Rasberrys time. When I click the 'Set time from NMEA' button I get Error 111 - Failed to connect with localhost: 10109.

Another problem is with the compass. OpenPlotter recognizes the compass chip but when i press the 'calibration' button nothing happens...

OpenPlotter is updated to the lates version

Do anyone have any ideas?

  How to filter double sigK keys in klpex?
Posted by: Alpenskipper - Yesterday, 01:19 AM - Forum: How do I...? - Replies (3)

Hi,

I installed the USB-N2K converter for the seatalk ng network.
The problem is, that I receive a lot of double sigK keys.

There are e.g. two SOG keys in sigK diagnostic, one is valid, the other one produces faulty values, that disturb the SOG reading.

Both values seem to come from the USB adapter. When I have a look on the PGNs directly, there are no double values.

I got the hint, here in the forum, to filter the faulty keys in kplex. I tried to set up a filter in manual section of the kplex.conf, but it did not work.

Could someone please point me into the right direction and give me a example how the filter is used?

Martin

  Update problems
Posted by: Kaya3 - 05-19-2018, 04:40 PM - Forum: General discussion - Replies (9)

I was just starting to get things working well and now I seem to have broken it.

The openplotter login screen said there was a new version available (10.0.17 I think). I tried updating using the openplotter GUI not the command line and got an error message saying something didn't work and did I want to exit the LXTerminal which I did.
I then changed the Pi User password and the Openplotter wifi password and rebooted when it said it was recommended. This reboot seemed fine I then changed the VNC password and tried rebooting again and nothing happens. The same thing if I try the shutdown option, the logout works but not the other 2.

Any ideas of what I've done?

If I use the reset option (shift key on startup) will that take me back to a fresh install state. (I haven't really set much up and it's still fresh in my memory so could probably run through it again)


  ultrasonic antifouling
Posted by: samdam - 05-19-2018, 05:30 AM - Forum: General discussion - No Replies

hello, I'm samuel from France and new on this forum Smile

I just started to build an electronic ultrasonic antifouling. If some makers are interested I can share what I found (electronic, source code, efficiency studies...)
My system is from the kit described in epe sept 2012: http://www.epemag3.com/proj/0912.html
It is based on a PIC microcontroller 12f675 (12F615 for mine), and seems to work nice...on the test bench [Image: 1f61b.png]:p
By the way I'm a happy raspberry / opencpn user since a few months (in fact opencpn added on a SDRplay system for meteofax and navtex, ais, NOAA sattelite images...).

I'm opening this OpenPlotter thread because the ultrasonic board may be easily modified for a raspberry or arduino instead of the PIC. That could be interesting to monitor and optimise frequencies (to find the best resonnances mode for each hull)..., manage power against battery state, I think we could even add a "receive" mode with a different transducer at higer frequencies (or harmonics?) to use it as a deepth sounder...(but what about dolphins? :p )
I 'm not very good at linux/programming so it will take a long time for me to integrate this on my RPI, but maybe someone else is interesteded to also test and develop this system?

  ESP32
Posted by: quetzal - 05-17-2018, 05:58 AM - Forum: Feature Requests - Replies (8)

Hello,

I've an esp32 and a board "m5stack" which include a mpu9250. I've bought planning to code an autopilot with it, but then i discovered pypilot.

Do you think it will be difficult to port pypilot to these boards ? (i've not yet looked the code of pypilot). Since m5stack support micropython, have a screen, the mpu9250, wifi, etc... it would be a good choice to keep a pilot without raspberry. I know python but i don't know the limitations of micropython (perhaps you don't know too Smile


Congratulations for making this pilot, it's the missing opensource part of sailing for the moment.


  Newbee question about AIS ans NMEA2000
Posted by: seawolf - 05-16-2018, 03:34 PM - Forum: General discussion - Replies (4)

I have spent som time looking at the documentation and i just want to check one thing. 

With a AIS from an SDR dongle, will that info be relayed to the NMEA2000 bus so i can display the ships on my plotter?

  Mikrotik Groove and Openplotter
Posted by: Kaya3 - 05-15-2018, 02:28 PM - Forum: How do I...? - Replies (7)

I'm having an issue trying to set up my Mikrotic Groove wifi extender with openplotter. I've managed to get it working connected directly to my win10 laptop using a static IP of 192.168.88.2
Subnet Mask         255.255.255.0
Gateway               192.168.88.1
DNS                      192.168.88.1
I was the able to access the groove using winbox (a windows utility provided by Microtik)

I'm both a linux and networking noob, but I was able to set up the same static IP in openplotter and was able to access the Groove via http://192.168.88.1/webfig/ which appears to be very similar to winbox but works outside windows.

I was able to view a list of available wifi networks but when I selected one and gave the password then tried to connect all I got was a status of searching and nothing happened.

I'm wondering if this might be a permissions thing in Openplotter that I'm doing wrong, or possibly something in the firewall that's stopping connection.

Does anyone have any ideas?

Any help would be greatly appreciated.

Colin


  Monitor sleep mode
Posted by: Kaya3 - 05-15-2018, 12:47 PM - Forum: Feature Requests - Replies (2)

Apologies if this is requested already.

In my setup and I assume most non-headless installs the main power user is the monitor. It would be great if there was a setting to put the monitor into sleep/standby mode (way less power usage) after a user set number of minutes then wake after a key press.

Our general usage would have one of the crew check the chart plotter whenever they pass the nav station say every 5 or ten mins possibly even longer if in clear water. The rest of the time the monitor would be drawing a lot less power.

The monitor can be powered on and off manually, but if this is an easy feature to add it would be a lot more elegant.
