Raspberry Pi help
I bought a Raspberry Pi with a touch screen and Bluetooth keyboard. I installed Raspberian Pixel OS and OpenCPN. But I cannot launch OpenCPN.
When I look for the Application folder it does not exist as far as I can tell. The instructions tell me that the folder should be in usr/local/share/applications/opecpn.desktop but I dont have this folder.
The installation process for OpenCPN went well, it only crashed once.
Anyone have any suggestions on how I can check to see if the program installed properly and how I can launch it?

Re: Raspberry Pi help
Reinstall without crashes but before you do erase the memory card.

Re: Raspberry Pi help
You could just install openplotter, everything you need plus more is in there.

Re: Raspberry Pi help
The first question is: should I have an Application folder?
I have other applications. Is this a standard folder? Or is it one installed by OpenCPN?
To reinstall, do I simply start from scratch? Do I need to update and upgrade the system too? Or just go right to the commands for OpenCPN?
I have no experience with Linux or Raspberry Pi.
How do you know when something is installed properly?

Re: Raspberry Pi help
Are you running openplotter?
If so everything should be already installed working with all the plugins.

Re: Raspberry Pi help
I am not familiar with OpenPlotter. I have used OpenCPN on my Mac.
I bought a generic Raspberry Pi and installed Raspberian Pixel OS.
I followed the instructions here:
King Tide Sailing: How To Install OpenCPN on a Raspberry Pi
I will take a look at OpenPlotter, but I might be in the same boat, as it were.

Re: Raspberry Pi help
Great info. I'm look at it right now. I'll download and install it later today.
Thanks!

Re: Raspberry Pi help
Everything installed flawlessly.
Now I just have to install some charts!
I'm going to order a DC power adapter and an external Lithium batter for my Pi. That way, I can plug it directly to my power system and have the security of battery backup in emergencies.
I have to also have to start reading up on all the support for NMEA and the sensors.
I see all the individual sensors they offer, is there a single package for all of them with some sort of mounting system?

Re: Raspberry Pi help
I've got a touch screen and a bluetooth keyboard, but I can't seem to access the Icons on OpenCPN's toolbar. What's the trick?
Is there a keyboard shortcut? Or do I have to use a mouse?

Re: Raspberry Pi help
Ok, I just noticed that my Pi no longer sees my wifi networks. There is no wifi network icon anymore. It shows a Wired network icon and when you click on the icon it drops down and displays
Ethernet Network
device not managed
Wi-Fi Networks
device not managed
VPN Connections
> Configure VPN
> Disconnect VPN
How do I get back on the Internet?

Have a look in the wifi tab in openplotter, might be set as an access point. Un tick the "enable access point" box if it is ticked.
Or if you get a wifi dongle openplotter can act as a wifi repeater so you just have to log in once to a new hotspot instead of every device.

Re: Raspberry Pi help
It looks like OpenPlotter wants to run the Wi-Fi chip on the Pi to communicate with wireless sensors. Can it do both? Or, do I have to turn off the wireless function to allow it to go on the Internet?
At the moment, I only have wired instruments and will be setting up a wired network on the boat.
