Open CPN

[sailaboutvic]

Opencpn two question
1 Have any one found a way to run Open cpn off an iPad and if so how?
If not

2 how can you use a remote connection, so you can use the PC to run CPN , while remotely viewing it on an iPad? Or is this not possible?

Just check question isn't breaking any rules

1. Opencpn won't run on Ipad AGAIK.

2. Should be able to, I run O on an android tablet but can use VPN to echo the screen of the Raspberry Pi as well. Bit low and clunky but it works. Really handy having such a good AIS display available in the cockpit. The Raspberry Pi creates a WIFI network or you can use a mobile phone to run a network and log everything onto that. .

About £90 will buy a 10" Lenovo tablet that will run OpenCPN, better than mirroring the PC, which is very "slow and clunky" as GHA says.

I've never heard of OPenCPN being ported to iOS.

As Paul Rainbow says, easier to run it on a cheap tablet and to leave the iPad somewhere safe.

Another option is to run opencpn on a raspberry pi and then use a remote desktop to view on an ipad. Pretty easy to setup if you have a pi, and all the software is free.

i dont mine buying a raspberry ( or a strawberry ) if you dont mine posting here or PM me instruction what i need and how to get it to work.

Works but not fantastic, not too bad just for viewing but doing any mouse work could lead to language banned on here

Not too hard to set up initially, then extremely powerful if you want to dig deeper. Doubt if there is a more comprehensive suite of software tools for a sailing boat computer around.

Then mirroring onto your ipad *should* work pretty much straight away, assuming there's a real vnc or similar app available for download on an Ipad. You'll still need to get gps/ais etc data into the little Raspberry Pi computer, but after that it beams it all around the boat over wifi so a laptop can see all the same stuff without any wires trailing around the place. Just charging.

What would it cost to get one to display OpenCPN on an iPad ?

35 for a pi3, 11 for a usb hub, say 3 quid for a 12v-5v buck power supply, maybe 15 for a couple of sandisc X10 16Gb SD cards, say tenner for couple of serial/usb converters if you don't have any already. And maybe a little case.

Software - free. But we're all generous so would send a donation VNC set up ready to go, most other set up via menus. Convert NEA-Signalk or vice versa, send/receive with MQTT then convert to signalk, masses in there mostly fairly accessible using menus rather than getting sleeves rolled up with command line stuff. Opencpn & all plugins pre installed.

For that you get AIS/GPS nmea0183 multiplexed and output over wifi as nmea & signalk, add maybe a tenners worth of sensors and you could have engine/exhaust etc temperature, barometer, compass maybe a fiver? Accurate voltmeter about a fiver. With wifi then monitor the boat, send email/mqtt/tweet for alarms of under voltage or whatever, or via a mobile phone usb link thing which I haven't tried.

January has been rumoured for release of a plug-in board with a load sensors -

• High-sensitivity dual channel AIS receiver with SMA antenna connector.
• High-performance GNSS receiver with integrated patch antenna and external antenna support via BNC connector.
• 3 status LEDs.
• Barometric pressure, humidity, temperature, gyroscope, accelerometer and magnetometer sensors. Sensors
  are directly accessible via Raspberry Pi. In standalone mode the sensors are controlled by the host micro-controller.

Thanks for that. I think that using it just to get OpenCPN onto an iPad doesn't make much sense, the cost is about the same (or maybe a touch more) than a cheap Lenovo tablet and it's a lot more messing around to set up.

It does start to make sense if the other stuff you mention is used as well. What options are there for display ? I do have a 12" tablet running Win 10, Laptop running Win 7 and a 24" LED TV, used to display the laptop output.

You say "For that you get AIS/GPS nmea0183 multiplexed and output over wifi as nmea". Where is that coming from, onboard systems ?

I run O on Mac MBPro. It is by far the best navigation kit to use, although a bit fuzzy in operation some times. But given the addition of an GPS/Glonass U-blox7, we navigated the very tricky waters of the San Blas Islands in Panama. We have also downloaded Google overlays for the Marquesas, our next destination.

My sole comment: get good kit, you'll be glad you did when you get experience on the software.

Merry Christmas

If you already has an AIS and GPS multiplexed in say GPS input to an AIS like the NASA device could you not use a RS232 to bluetooth of wifi and on your W10 laptop / tablet find that data into OpenCPN.

Using something like this

Don't want to cause any confusion, i already have a MUX/router that broadcasts all onboard data via wifi to the tablet and laptop, both of which can also be used stand alone.

Reasons i asked about the Pi were ;

a) is it really a cost effective and viable alternative to a cheap Android tablet. I don't think it is if it's only used for based nav.

b) Out of interest as a bit of a project. If i can find the time to play with it.

My thinking may not be of interest to you but is of interest to me and may be others.

Anyway this was a reply to GHA so I was asking him

I am already playing with the Arduino and used the old 8051 microcontroller in projects before retiring.

I also follow GHA's threads with interest.

Sorry, my crystal ball is offline, i thought you were replying to my post

I also read his threads about what he's doing with the Pi with interest.
