connection to plutosdr / soapy remote #59

Closed tmlll closed 4 years ago

tmlll commented 4 years ago

Is it possible to connect openwebrx to plutosdr with SoapyRemote?

I have installed openwebrx on raspberry pi and I would like to connect it with plutosdr in SoapyRemote mode via tcp.

What do you need to enter in /etc/openwebrx/config_webrx.py in the sdrs = {} section?

jketterl commented 4 years ago

It should be possible, even though that specific scenario hasn't been used yet, at least to my knowledge.

The soapy_remote sdr type follows pretty much the same config scheme as the other drivers apart from a few special keys: remote and remote_driver. So a very basic config example woud look like this:

sdrs = {
    "pluto": {
        "name": "Adalm Pluto",
        "type": "soapy_remote",
        "ppm": 0,
        "remote": "192.168.123.456",
        "remote_driver": "plutosdr",
        "profiles": {
            "20m": {
                "name": "20m",
                "center_freq": 14150000,
                "rf_gain": 20,
                "samp_rate": 500000,
                "start_freq": 14070000,
                "start_mod": "usb",
                "antenna": "Tuner 2 50 ohm",
            },
        },
    },
}

I'm not sure if the profile is even useful with a Pluto, I have only quickly adopted another config I had at hand.

As you can see, remote is the target IP or hostname, whereas remote_driver is the soapy driver identifier on the destination machine. remote_driver is optional, if omitted, the destination will choose the first available soapy device.

Thanks for your reply.

The example configuration has worked with PLUTOSDR since the first start. OPENWEBRX worked correctly, I mainly tested how APRS decoding works.

The problem is that when after a while I turned ON the computer again and I opened the OPENWEBRX website, I could not connect to PLUTOSDR again. I spent a long time trying to solve the problem but couldn't connect. Raspberry and PLUTOSDR restarts did not help. Finally I gave up.

The next day I came back to this. After long tests I came to the conclusion that in order to run OPENWEBRX and PLUTOSDR I need to change the IP address with which SoapySDRServer starts.

For example, if it was before:

# SoapySDRServer --bind
######################################################
## Soapy Server -- Use any Soapy SDR remotely
######################################################

Server version: 0.5.2-g03b483ad

Press Ctrl+C to stop the server

next time I launched:

# SoapySDRServer --bind="192.168.20.1:55132"
######################################################
## Soapy Server -- Use any Soapy SDR remotely
######################################################

Server version: 0.5.2-g03b483ad

Press Ctrl+C to stop the server

When OPENWEBRX is working properly, SoapySDRServer only establishes the following connections:

SoapyServerListener::accept(192.168.9.7:44746)
SoapyServerListener::accept(192.168.9.7:44764)
SoapyServerListener::accept(192.168.9.7:44768)
SoapyServerListener::close()
SoapyServerListener::close()
SoapyServerListener::accept(192.168.9.7:44770)

During normal operation, the OPENWEBRX log looks like this:

The above logs show the connection of only one OPENWEBRX client. I tried different connections PLUTOSDR, LAN, WLAN, different IP. All on the local network. The connection can only be established after reboot raspberry and pluto and when the SoapySDRServer address changes.

I use in openwebrx config:

"remote": "192.168.20.1"

I also use this PLUTOSDR with Soapy Remote and SDR Console and I have no problems with it. I have no more ideas. I use experimental repo for raspberry now, but the problem is the same.

I think this is a soapy_connector problem, but maybe I'm wrong.

After issuing the following command, SoapySDRServer behaves similarly, closes the connection repeatedly, and reconnects:

soapy_connector -s 2400000 -P 0 -g 30 -d driver=remote,remote=192.168.20.1,remote:driver=plutosdr -f 438800000 -p 38181 -c 37237

I also did short tests on another machine, running OPENWEBRX in a container but without success.

If you had a problem with it or maybe you had an idea, please help.

well, i don't have any immediate conclusions. the soapy_connector doesn't do much with the information you give it, it mostly just passes them to the soapy libraries. I don't see any errors either, which makes debugging harder.

I see you are running the latest SoapySDRServer version, but I don't see which client library version you have installed. If you did install from the package repository, you're probably running version 0.4.3, which is a bit dated. It might be worth trying the current version (https://github.com/pothosware/SoapyRemote) on the client, but you'll need to install it from source.

Another thing that might help (at least as a work-around) is the "always-on": True option, which will keep the connection open and running. Of course that will cause network traffic at all time in your case, but it should prevent this issue.

Sorry to Hijack this issue but I dont think it is worth its own issue.

I am trying to use soapyremote to connect to an RTLSDR but I get:

owrx.sdr - ERROR - The RTL source type "soapy_remote" is not available. please check requirements.

Have I missed something in the SDR config?

`sdrs = { "rtlsdr": { "name": "RTL-SDR", "type": "soapy_remote", "ppm": 0, "remote": "192.168.0.56",

you can change this if you use an upconverter. formula is:

    # center_freq + lfo_offset = actual frequency on the sdr
    # "lfo_offset": 0,
    "profiles": {
        "70cm": {
            "name": "70cm Relais",
            "center_freq": 438800000,
            "rf_gain": 30,
            "samp_rate": 2400000,
            "start_freq": 439275000,
            "start_mod": "nfm",
        },
        "2m": {
            "name": "2m komplett",
            "center_freq": 145000000,
            "rf_gain": 30,
            "samp_rate": 2400000,
            "start_freq": 145725000,
            "start_mod": "nfm",
        },
    },
},

}`

@Heppie you're probably missing a piece of software. Please check the feature report by appending "/features" to your receiver URL (e.g. http://localhost:8073/features) and make sure that all dependencies listed under "soapy_remote" are available. Depending on what installation method you went with, you'll need some extra packages or need to compile from source.
