Monitor messages on Raspi

[SFSailor]

I have the program running on a Pi Zero W. New at this. Some questions

• Is there a way to monitor the actual messages coming in? I get counts in the GUI but not the actual messages.
• The Webviewer does not work but gives the message "10.0.0.95 refused to connect."
• I connect to the RTL-SDR v3 on USB when using the GUI, but it says it cannot find the device when using the command line interface...
  Any advice?

Well, I got it working now, and am seeing the values on Putty. But still no webviewer

Ok, so you are running on a RPI and have the program running (assume starting it via Putty) and you see the NMEA on the screen?
When you add -N 8100 to the command line (or activate in the GUI) what does the program say when you start it?
You are trying to open the web interface (with the map) from another machine I assume. In the browser, if you go to http://<IP of the Zero:8100 what do you see?

Bit more logs and details would perhaps help to clarify

When I start via Putty yes, I see NMEA on the screen.

Starting via gui from my windoze laptop, here is the log:

That is at xx.xx.xx.xx:8110 which all works fine except for the webviewer tab. That SHOULD give me a map or chart and instead gives me a little sad face and eventually the "refused to connect" message.

I am running on a raspi zero W, using the precompiled debian distribution as the program won't compile on my device, stalling at 40%

Ok, I suspect the webviewer is not switched on. Can you go to Output -> Webserver:

Ensure that the webserver is active at port 8100:

Then scroll to the bottom and press Save to store the new settings. And then go back to Control to Restart the program. You should then see something in the log like:

If that is the case, you will have the webviewer at the same location as the GUI but then at port 8100.

Is that perhaps the issue? The webserver does not run by default.

Well, that was precisely it. I did not realize it needed to be on. It's working now and I am getting a very nice set of signals from a very slapdash installation! On to the next issue!
