SoapySDR remotes aren't matching

[akhepcat]

I'm unable to select a remote device using SoapySDR's driver syntax, even thought SoapySDRUtil can find it:

$ SoapySDRUtil --find="driver=remote, remote=192.168.1.184, remote:driver=rtlsdr"

There aren't any examples, really for doing this type of connectivity with the code, but it seems like it should work as other applications (CubicSDR, for example) can use the same remote sdr source just fine. It's most likely something to do with the driver selection in the command line, but without any good docks here, i'm just trying various combinations and still getting nowhere.

Is this using https://github.com/pothosware/SoapyRemote? I'll add support for this.

[wcampbell0x2a]

Thanks for showing me SoapyRemote, pretty cool application.

Maye I need to make it clearer, but this is already supported and it works on my machine. The --driver already has the driver= by default, so removing the driver= makes this work perfectly.

dump1090 --driver "remote, remote=localhost, remote:driver=rtlsdr"

I'll close this issue, let me know if this doesn't work for you.

[wcampbell0x2a]

A minor point. you would need the following in a config file:

# rtlsdr
[[sdrs]]
driver = "remote, remote=localhost, remote:driver=rtlsdr"

[[sdrs.gain]]
key = "TUNER"
value = 49.6

Sorry was on a plane yesterday, but this still doesn't work here.

And this is after doing a fresh git pull just now.

and yes:

/usr/lib/x86_64-linux-gnu/SoapySDR/modules0.7/libremoteSupport.so

works fine with CubicSDR

Here are all the commands, I haven't tried on a non-localhost so maybe that's the issue?

Yes - i have the server running on the remote host, and the local host is able to see it and bind to it using SoapySDRUtil, as shown in my comment.

I'm unfortunately not in the same state as the remote, so I can't move it between hosts. But the "SDR server" and the "dump1090 host" are on the same local segment with no firewalling, so it does seem that it's an issue with non-local connections.

• forgot to add, also tried with a resolvable hostname instead of the bare IP, and that did not work either/

Not sure if this is useful:

I think my build is working with soapyremote-server on a remote system:

Ah, I see now, i'm using the wrong "driver" :

So, it's just the syntax. Time to update the documentation to make this a bit more obvious.

Thanks, @jfath for the validation and hint toward my actual issue.
