Re: Sending GX2150 AIS NMEA data to chart plotter over Bluetooth
what did you do to get opencpn to to load charts faster?
I created a separate chart directory that has vector and raster directorys in it and then I pointed opencpn to the top level chart directory.
I accidentally had two copies of the charts in two different subdirectories that OpenCPN was accessing through the top level directory. This was confusing the program and causing slow loading and crashes. Eliminating the duplicate copies was the single biggest improvement I made.
In addition to that, I minimize the number of charts that are available to OpenCPN by moving them out of the directory if I don't need them. Also, you will have noticed that OpenCPN needs to build some support files the first time a chart is accessed, so I make sure to do that ahead of time, so it doesn't have to do it when I'm relying on it for real-time use.
With those tweaks, OpenCPN has no problem running on my little netbook with Atom processor.
