  Wireless MQTT Data Display
Posted by: abarrow - 10-29-2018, 04:41 PM - Forum: How I did it - No Replies

Coding for my first adventure in MQTT is done. I needed a data display for the nav station that always gave me lat/lon speed, etc. Easier to glance up at something when I'm doing log entries.

Now, what is always the harder part - finding a case that looks decent.
(Not understanding why I can't insert an image here...)

  Openplotter settings dialog window too small
Posted by: NaturalBornCamper - 10-29-2018, 09:59 AM - Forum: How do I...? - Replies (2)


when trying to add a I2C sensor or do anything that opens a dialog window in openplotter, the window is too small so the "ok", "cancel" and other infos are hidden. Even if I try maximising the openplotter setting window before, it still opens that small dialog window that cannot be resized.

Not sure if this is a Debian issue or openplotter but I have a feeling there's a way in Linux to force resize windows.. just can't find it on Google.

Anyone knows?

  Openplotter v 0.8.0

Hi, how can I get back the openplotter 0.8.0 version?

  Standard TX/RX Serial to USB for Autopilot with Latest OpenPlotter Release
Posted by: svbalachandra - 10-26-2018, 09:09 AM - Forum: General discussion - Replies (5)

I've got the latest Open Plotter Release on a Raspberry Pi 3B and so far so good. I've had trouble with the cheaper 2-pin Serial to USB connectors where they don't have a unique serial number, and for some reason assigning by port location forced the PI to choose only one (one of three) adapters to favor and ignore the other two. I only paid $4 for these cheap ch341 chipset adaptors, so I ditched two of them and bought a better quality Nextech serial to USB adaptor with the 5 wire pinout and TX/RX led indicators.

I'm using this new adaptor to talk to my Raymarine Autopilot and compas via NMEA0183 in/out wires.
I'm following the documentation in your how to PDF file linked to in this forum to test out my connections using the diagnostic buttons, but the PDF hasn't been updated since the last open plotter release. There is no longer an option under serial port direction for IN/OUT or BOTH - only IN or OUT but my adaptor is a BOTH type adaptor. How do I test out the datastreams on both the RX (IN) and TX (OUT) ports on my single send/recieve adaptor to make sure I've got connection and NMEA0183 data?


  Wind Sensors
Posted by: abarrow - 10-24-2018, 07:46 PM - Forum: General discussion - Replies (9)

Hi all,

I've been searching a lot for a wind sensor that I can use with OP. It appears that the Tindie decoder for the Peet Bros sensor isn't available anymore (although I'm not sure I want a Peet Bros sensor).

What is everyone else using? Anyone tried an ultrasonic sensor? Are sensors like those that come from Davis robust enough to be used on the masthead?

  TCP In from iPad
Posted by: johnwilde - 10-24-2018, 05:52 PM - Forum: How do I...? - Replies (11)


Absolutely loving Openplotter - thanks for all the hard work people have put in.

I have one challenge, I can't get data from iPad (running iSailor) back to Openplotter (mainly autohelm controls so XTE sentances).

I can establish a TCP connection from OP to iPad - works great. If I try to make this bi-directional, it loses connection.

If I try to create a separate TCP connection for iPad to OP (with a unique port), the connection won't establish.

I tried using bidirectional UDP, using the IP address of the iPad and one port (set as both in and out). The OP to iPad connection works and iSailor gets data, but XTE signals aren't sent back (the iSailor trace doesn't even show it).

I can create a separate UDP for OP to iPad UDP  which works, along with a separate iPad to OP connection. On iSailor, this show a trace of XTE being sent (for a period anyway), but on OP Diagnostic it isn't received. This seems to be closest I can get.

Here is my config:







Any help - would be greatly appreciated.



  Getting SDR AIS to work
Posted by: Jodel - 10-24-2018, 04:14 PM - Forum: How do I...? - Replies (1)

I have a Pi3 running OpenpPlotter  1.2.0
I am using an RTL-SDR which worked fine on a previous version of OpenPlotter.
It is recognised and I have calibrated it as described in the Docs. Gain (48 PPM -212)
When I take a look at the signal I have strong vertical lines running down the screen.

The problem is that no AIS data is appearing in OpenCpn (It is enabled)
Do I need to set up an AIS connection in Kplex?

Any suggestions as to how to fault fine this issue?
The boat is in an area where there is lots of AIS transmissions.


  PyPilot Software
Posted by: rramsey - 10-23-2018, 03:11 AM - Forum: General discussion - Replies (1)

Hey Sean, I read a lot about PyPilot hardware. However, I feel it ultimately is the software that will make the difference. Do you have a description of the features? I am not a programmer so please do not refer me to the source code ...

Does it learn itself? How does it deal with waves and swell? Stuff like that. Is there anywhere you could refer me to?

  PyPilot as a Raymarine or Navico AP
Posted by: rramsey - 10-23-2018, 03:08 AM - Forum: Feature Requests - Replies (4)

I have both a Raymarine and a SIMRAD (Navico) mfd's. Both have the ability to control their manufacturer's AP.

Would it be possible to add software to PyPilot to make is masquerade as a Raymarine or Navico AP? Currently there is no standard for AP control, so control is proprietary.

I am not talking about APB sentences etc. I am talking about full control of the AP from my SIMRAD or Raymarine mfd. Left, right, on, off, mode et cetera.

Like a layer over PyPilot sending and receiving proprietary sentences ...

  DIY 10" sunlight readable plotter
Posted by: BellaX - 10-22-2018, 05:42 PM - Forum: General discussion - Replies (8)

Hi all,

i am using OP since beginning of 2016 with a RPi 2 and RPi 3 and the original 7" display
and the 19design enclosure. I am still impressed about the success of OP.

The 7" display is OK for general navigation. But if you want to display some readings,
compass or wind vane the display becomes too small and it is unreadable if the sun shines
directly to it.

So I was looking for alternative displays, monitors, tablets and so on. I am sure some of
you have had the same idea and you have found some overpriced marine monitors and
nothing else. Having a tablet with waterproof case on deck using vnc is not really what i want.

Time to build your own?

Two weeks ago I have ordered a 1200 nits sunlight readable 10.1" display from china.
Together with a touch-screen and hdmi-lvds controller board. Costs are $110, shipping
via DHL included. The LCD alone is around $55 without touch, pcb and shipping.

My idea is to take a Raspberry Pi compute module which is a RPi without all the connectors
and unwanted electronic that fits to a 200pin DIMM socket like the elderly RAM modules.

The disadvantage is you have to build a pcb with all the electronic needed. This means power
supply, usb hub, hdmi to lvds interface and so on.

The advantage is you get access to all the connections of the RPi. And you don´t need any
cables except the power cable if you include all the electronic you want to this pcb.

The goal is basically a sunlight readable RPi enabled monitor.
 It could be improved by compass, imu and other sensors, as well as interfaces like nmea.

If there is some interest we could start a forum project on this.

All the best,
