By forwarding the correct ports on your router, you can connect to the VNC service over the internet, everything is already installed on the pi, you just need to open the port and install a VNC client on the computer.

You need to know the outside IP of the pi's internet connection.
Be aware that forwarding ports come with some risks, so use a good login password etc, and only open the VNC port.

Hi Alekoy

Thanks for your reply and it will immediately be obvious to yoou that you are dealing with a newbie. If I go ifconfig I get this:

which ip address do I use, as i tried all of them but get o loopback"errors with VNC'many thanks and apologies,

[Alekoy]

No problem, I used to be a noob myself

Just open a browser (works on any computer using the same internet connection) and visit www.whatismyip.com the external IP will be in big bold numbers

Your connections IP might change, so you might want to set up a DynDNS or aomething, but that is another story

[richarddaneel]

thanks for the help, tried it and got the error, failed as receiving computer actively denied it, how do I enable OP on the RPi to allow VNC, thx

[hwater]

You are behind an so called NAT Router. If you really forward the VNC Port you have so set this Router translate his adress/port to your private (not routable) adress. in your case (ifconfig) 10.10.10.1

But it is an really big security hole as the password is only hashed and not crypted in the internet.

Better try to setup your aund your pi to connect to an VPN Server and therefore meet on your own network without hassle. You should find the docus to setup an VNC-Server on the VNC Usergroups.

Good Luck

Much as I hate to throw a spanner in the works, in post #9 sailoog mentioned that when configured as an access point 10.10.10.1 is the default ip address openplotter assigns itself.

Is richarddaneel's pi even connected to the Internet?

I have built my own MCP3208 fuel sender reader and bargraph display.
It runs off the SPI interface and is connected to my resistive fuel gauge sender. I've shamelessly copied code from others in order to write a little python prog which captures fuel level data and displays it on an Adafruit LED bargraph over I2C. (Works just great)

I'm installing my OpenPlotter Pi on my boat on Friday but I don't want to go too far "off-piste" with my developments as Id rather stick to the Openplotter framework

You are right, The Cloud won the position to the analogue sensors but now I have already come down from the clouds. We have done some work on it and I say "we" because there are more people involved now. There is a guy helping with code and another one working on a ADC board. These was the good news, the bad ones are that we have realized that we need to do some work before...

Nowadays we have some non NMEA standard data from sensors: heel, pitch, pressure, air temp, humidity and temp from multiple 1W sensors normally from engine. We are streaming this data in XDR sentences in a non standard way. When we implement analogue sensors this list will increase. So, we have exciting data but we do not have much to do with it. By this moment all this data can be managed by the trigger/actions system but we do not have a way to visualize it, yes the famous gauges again.

Then we have decided that first of all we need to do the obvious step, totally implementation of signal k. That means allow the user to select what signal k property wants to assign to each sensor.

I will try to work in parallel, implementing signal k to sensors and creating the SPI analogue interface.

Sorry, I know you have been waiting for long time. No more Clouds, SMS...

In the "WiFi AP" tab there is a column named "Addresses" where you will find always all the active IP and ports on your system.

If you want to access to OP from internet you need your public IP (as Alekoy suggested) and to open the ports on your router (difficult thing if you are connected to the marina router).

Hi sailoog

I have a barometer and accelerometer hooked up to i2c and if I go to sudo i2cdetect -y 1 I can see it picks it up, no problem. If I go to the OP i2csensors page I can see it has picked up the sensors. I then select them but no data and NMEA strings appear in the inspector page. Is there a command I can use to see the data coming from the sensors (i2cget ???). thx

[Didier B]

In my case,I had to reset all sensors, restart OP and reselect the sensors, then they appeared in the inspector window.

Hi Sailoog

Please could you let me know which version will work on which RPI. For example, on my RPi 2 I used ver 6 but I see it does not work on RPi 3 not sure why I just get the start-up colourful block then nothing. Also, will the newer ver 7 and 8 work on RPi 2? thx

The "start-up colourful block" is likely an issue with your power supply being under-powered; The Rpi3 uses a lot more power than it's predecessors.

Version 7 works on My Rpi3 but I did have to sort out problems with the power supply.

Cheers,
JM.

[Saqqara]

I don't think that's correct advice: when the Pi3 came out the then-current version of openplotter that did exactly that rainbow on boot, and support was later added. Start with the latest images and you will be fine.

Of course the Pi3 DOES demand more power, so it could be both things.

With a "reverse public tunnel" (my expression) tool like https://ngrok.com/ you can create a tunnel from a publicly accessible host to a server running locally behind a NAT + firewall + service provider restrictions. I've successfully published onboard sailing data with a Signal K server + sailgauge/instrumentpanel.

Another option for private remote access is setting up a VPN. I can access my onboard SK server or the RPi via ssh by opening a VPN connection to the onboard VPN server. Access to your MFD with the tablet apps should also be possible, but can't yet vouch for it.

For those willing to go with Ansible setting up a VPN over 4G uplink: https://github.com/tkurki/marinepi-p...ia.yml#L29-L43

Maybe OpenPlotter could include either or both of these techniques as options?


Maybe OpenPlotter could include such functionality as an option?

Hi guys,

I have created a version of RTIMULib2 to handle my IMU MPU9255.

So how do I replace/update the libraries within openplotter?
I have compiled the RTIMULib , RTIMUDrive* , RTIMUDemo* libraries.

Openplotter can see the bmp180 sensor but not the IMU (greyed out), when I "reset and then calibrate " the RTIMUDemoGL sees my sensor.

I am using a Raspberry pi 2 and version 0.8.0 beta.

Any ideas and help grateful accepted.

Thanks
