SDR AIS available in OpenPlotter 2

[verkerkbr]

At first I tried this on my AMD64 system. Install from the OpenPlotter Settings gave an error about a postinstall.... file missing.

Then I installed the application from Synaptic. No error with the installation. Switched on the Ais application.

It seems to be working. But looking at the "sudo systemctl status openplotter-rtl_ais.service". There the outcome is displayed as "disabled". Switched the autostrart on and rebooted the system. Now the message is "enabled" . However I have not seen any objects passing by. But perhaps there are no ships here at rhe moment.

Then I did the same thing on my RPI4 with the V8 kernel. All seems to work. Message enabled.

But in the end i get the message:

Detected Kernel usbfs nmap () bug. falling back to buffers in userspace.

what was the missing file in your AMD?

That is the expected behavior for enable/disable status

You need to provide the correct ppm to see AIS blanks and to have some ship around of course

I can not help with errors with beta kernel because we use only stable kernels to develop

Just found the missing file with the first install on my AMD64 from the OpenPlotter settings: sdrhtPostInstall file was missing. Error was gone after install via Synaptic.

Everything seems to work. Although no ship to be seen.
