Problems with decoder / receiver / backend #3

Closed bi3mw closed 7 months ago

bi3mw commented 8 months ago

Hello, I have a problem when starting tar1090. The following error message appears:

Problem fetching data from the server: Seems the decoder / receiver / backend isn't working correctly !

I have connected a SDRplay RSPdx. Is this device not supported ?

I've only tested the snap with an RTL-SDR device, not sure if it works with others

It seems the device is not supported:

ads-b.dump1090[122139]: Sat Jan 20 15:55:32 2024 CET dump1090-fa unknown starting up.
ads-b.dump1090[122139]: rtlsdr: no supported devices found.

All right, thank you.

You could try finding out if the device can actually be supported by dump1090, and what compile options are needed in that case.
