Hi All ounce the kit is sorted, then it be used on the boat So in terms of Show us your hardware: Don't think it be any anything like Rikky's with a place to make boats and nav room so here is what the bits are going on , I have one of These Mitchell 31BR Alex |

Hi Rik & all
possible see why getting opencpn a problem
latest Buster PI4 ios images march 2021
cut short here :: opencpn web site PHP version
this how I got opencpn in
latest vesion of rpios / march
for raspberry pi4
sudo nano /etc/apt/sources.list
add for Buster
deb http://ppa.launchpad.net/opencpn/opencpn/ubuntu/ bionic main
save the file and exit
then
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C865EB40
sudo apt-get update
sudo apt-get install opencpn
BR
Alex
I added the ttyUSB0 and correct buad rate for my device & viola
BR

Looks like you don't have a problem with Brexit.  I'm overwhelmed by this new Operation System from OpenPlotter. OpenCpn pre installed is just for starters. A lot of crap that you don't need isn't there, and a lot of things I never heard about, but always wanted is pre configured and ready to use. KPlex it is, NOT SignalK, that multiplexes all your data, like the AIS etc, etc A VNC thing to which you can log in remotely to openplotter.local, that I never succeeded to get to work, is preconfigured and ready. A WiFi repeater build in, that can talk to you (your devices) and with for example the Marina, to pass trough the internet, but also apparently to pass through just OpenCpn Did not even know this was possible. I thought you can either connect to a Marina OR connect to your devices, NOT both at the same time. Have NOT tested your gps program though, for I am too scared to break anything. I'm too happy to have something running, without having to buy a big laptop. will prepare an other Raspberry for testing and messing around with soon.  |

Oke my mistake. Kplex is not even installed on my system. In SignalK you can register your AIS, with everything like port /dev/ttyUSB0 baudrate And then it sends the data over the internet at 10.10.10.1:3000 Then on another device you install OpenCpn and configure your AIS port comming from 10.10.10.1:3000 Don't know if it works, but it works using localhost:3000 on the same machine. Haa, now you have your AIS computer headless |

Hi All
have modded the serial port to use exec$ to receive the decode NMEA see first post
Adapt paths to suit . the decoder name here is gpsdc at the EXEC$ in tha Function callback
the serial driver
Adapt Paths cssl.h and the cssl.c
Adapt the serial port and baud rate to suit

Before I broke the sim card I had download a ais decoder in c , it would not compile an hence set a thread Navigation(ais) to use the gpsd Downloaded again and have done some mods to the source code , now it compiles so will be testing that + working on the gui in mean time as regard equipment and access ,, these devices are generally available with usb or can use rs to usb,, as mentioned by members can only access one bit at time and some ideas about network I leave you with some food for thought USBIPwww.linux-magazine.com/Issues/2018/208/Tutorial-USB-IPBack soon BR Alex |

Interesting this usb_ip Will read about it later. But still you can open your device only for one user. Wether locally or remote. So tried this from another Raspi (Told you not to throw away your old Raspi 3('s)) curl -s GET openplotter.local:3000/signalk/response: So we have Don't know what ws:// means or what to do with the tcp or how to use the severnode (yet) curl -s GET openplotter.local:3000/signalk/v1/api/result: a horrible lot extract from the result: UNJSONED result "vessels":

Possible getting a little off beat at this stage :: Add Json weather
can try

Dear Alex,
Thanks for reminding me of wttr.in. That json provides a lot of information - including forecasts and the likelihood of precipitation. Parsing those bits and formatting could give us a nice little weather app without too much work.
With kind regards,
