  problem with the wind signal
Posted by: HALLEY - 03-10-2019, 05:55 PM - Forum: General discussion - Replies (1)

I have a problem with my openplotter .... I have always received the wind signal in OPENCPN, speed and direction and one day without doing anything it stopped working ...
It marked the direction and the speed and suddenly it stopped. Then he marked the wind speed he wanted, almost always more than normal.
Now I just check the address and it does not show me the speed, and from time to time it stops
Some help?

Thank you

  AP gone after upgrade
Posted by: PaddyB - 03-10-2019, 07:44 AM - Forum: Bug Reports - Replies (8)

Just did an apt-get update/upgrade and now the Pi access point isn't there anymore. There was a warning about hostapd which I didn't pay much attention to, installing this by the looks of it >
hostapd:armhf (2:2.4-1+deb9u2, 2:2.6-21~bpo9~rpt1)
Anyone else seen this? Is there an easy fix?

That was easy Cool

$ sudo su
# apt-cache madison hostapd
hostapd | 2:2.6-21~bpo9~rpt1 | stretch/main armhf Packages
hostapd | 2:2.4-1+deb9u2 | stretch/main armhf Packages
# apt-get install hostapd=2:2.4-1+deb9u2 -V

Back in action again.

sudo systemctl enable hostapd.service
seems to work as well without rolling back.

Exclamation Wrong baud rate
Posted by: Acer - 03-09-2019, 12:38 PM - Forum: General discussion - Replies (2)

I just got the can.usb stick and it worked fine, but then I made a mistake: in the openplotter Setup menu /can there is this tx pgn enable list….and there is set the baud rate to 230400. No I just receive nonsense and I cannot enter tx pgn ebable list to set the baud rate back to 115200.

Any help is welcome


  Update problem on RPi 3+
Posted by: Bill_ Maxwell - 03-08-2019, 07:19 PM - Forum: General discussion - Replies (22)

My installation of OpenPlotter on my two RPi has proceeded smoothly, using the NOOBs package downloaded from the homepage. In the end, having found the RPi3 I bought a year or so ago, I used that for one system, a RPi3+ for the second. 

Having gotten that all working, after a few days I grew tired of the start-up message telling me that a later upgrade was available, so I set the RPi3 version off on that task. It performed flawlessly. 

I then tried to have the second system, on the RPi3+ perform the upgrade. It got through most of the process, up to the point of asking for my input as to whether to proceed or not, whether to read the Change Log etc. On my entering "Y", it started to install but then aborted, asking for an "enter" t exit. On getting that, it goes back to the previous version but not without producing some strange results there too, including on one occasion, the loss of the OpenPlotter icon. Fortunately, the NOOBs Restore function reproduces a normally operating older version.

I tried this upgrade numerous times, before reformatting the SD card and transferring the NOOBs files to that, then reinstalling OpenPlotter. Same result, an aborted update.

In frustration I then took my second RPi3+, brand new in its carton, downloaded the NOOBs package afresh, unzipped it, took a brand new 32Gig SD card, formatted that, copied the NOOBs content files over, set up the fresh RPi3+ and let it build the system. That worked as expected, so without doing anything else to that fresh install, I then requested OpenPlotter to update. Same failure at the same spot. Happily OpenCPN updates without issues.

If I had any hair remaining I think it would be torn out about now Huh . Can anybody offer any suggestions on this problem? I can certainly operate on the version NOOBs gives me but that is at least 2 behind the current release, which OpenPlotter itself tells me is a major upgrade, so I certainly want to use it.


  How do I get gmail working

New user.  I setup a high water alarm and followed up with an action to email.   I setup the account on gmail and enabled.    It is trying to send but saying authorization failed bad credentials.
Obviously I have confirmed them and I can sign on manually.    Is there something else I can do?

  MOB Feature
Posted by: quetzal - 03-06-2019, 07:00 AM - Forum: Feature Requests - No Replies


It will be good if we have a feature on pypilot to stop the boat, like in nke pilot.
I think a signal-k sentence to stop the boat can make this:
 - if there is a windvane, the boat face the wind
 - if there is no windvane, the boat go to heave to

Il would allow to use some cheap bluetooth tracker, and, with a separate process, when the link is lost, the process stop the boat. In solo sailing, this will potentially allow a man overboard to come back in the boat.

  Apple Client
Posted by: mikeh - 03-05-2019, 04:03 AM - Forum: How do I...? - Replies (2)

would anyone be able to share their knowledge of connecting an app to the rpi as a client? I would like to build an app that displays Engine data but am unable to connect to the rpi server. I am using the signal k script for apple since javascript into the Android base code is not clear to me. The code provided by signal K for apple client was used and cocoa pods were installed correctly shown on the following link.

host used is: "10-1-1-40.local"
port used is: 3000

why would the error code: "Request timed out" keep appearing? Running into my browser opens up signalk. Also, is there better instruction for running a client to retrieve data in an Android app then is provided by SignalK website?


  CPU temp fan controll
Posted by: Didier B - 03-04-2019, 12:15 PM - Forum: Feature Requests - No Replies

Angel  It would be soooo nice to have an option to control fan speed based upon CPU temperature. I know the dev team is willing to keep OP as lean and clean as possible, but this is a real need as any enclosure will see temp rising and rising, and these mini fans are so painfully nosy ... Angry

  Adding environment.rpi.temperature in trigger list
Posted by: topodom - 03-03-2019, 09:29 PM - Forum: How do I...? - No Replies

Hi everyone,

I had a problem this summer, my pi temperature processor got high.

I want to add a fan to lower the temparature in the pi box.

For that i will use a relay plugged on the GPIO and swich the GPIO on 1 when CPU temp is too high.

I made some tests with a fake value (environment.inside.temperature) and it's working well with openplotter actions (define a gpio output, then a trigger then an action).

Now i want to get rpi cpu temperature.
For that i have installed a plugin on signal k serveur to monitor the cpu pi temperature who's addin a "environment.rpi.temperature" key.
i can see the value and the key in signalK diagnostic in OP.

But when i a am going to action > add trigger, i don't have the Signal K key (environment.rpi.temperature) in the list
how can i set that ?


PS: i know there is an option with red node but i'd like to manage in OP:


  Documentation links not working?
Posted by: Bill_ Maxwell - 03-01-2019, 11:33 PM - Forum: General discussion - Replies (8)

I am a newcomer, setting up 2 RPi3B+ with OpenPlotter. I have both installs working but am having some difficulties in completing the setups, because some of the pages in the Documentation are without content, just giving the buttons to go forward to the next page or backwards to the previous page. Examples include "Charts", which would seem fairly significant, Signal K Server, Diagnostics, Signal K to NMEA0183 etc. etc. I have had this problem for the past week. Are the links perhaps broken? Huh
