ADSB & JSON Config

[CaptainSteubing]

Been enjoying AIS-catcher for a few years now (Docker). Thank you!

Moved over to AIS-catcher-control, and noticed that the Docker image is not updated quite as regularly. So I decided to move back to regular AIS-catcher using the JSON Config that was created in AIS-catcher-control.

Is there a way to get the ADSB input when you're using the JSON config file? (-t basestation X.X.X.X 30003)

I've tried it in the "command" stanza of the docker-compose file, but doesn't seem to work in conjunction with "-C /etc/AIS-catcher/config.json".

Thanks!

Hi and thanks! It is a bit tricky syntax-wise as you essentially want to run the program with multiple input streams. This means that you need to create a receiver array in your JSON that is an array with an object for each input stream, defining the source and the settings. At the moment, you might have put the definitions for the RTL-SDR etc in the root section, that is not possible if you have multiple devices. Have a look at this example. Does that help?

{
    "config": "aiscatcher",
    "version": 1,
    "receiver": [
        {
            "input": "rtltcp",
            "verbose": true,
            "rtltcp": {
                "protocol": "raw1090",
                "host": "str",
                "port": 30003
            }
        },
        {
            "input": "rtlsdr",
            "rtlsdr": {
                "tuner": "auto"
            }
        }
    ]
}

a ha! thanks for this. My other comment from today may have been answered here.

[jvde-github]

Same question indeed. Will add to the documentation in the coming days.

@caseyd,

Here's the snippet that worked for me thanks to Jasper's help.
Argh, can't get it to look nicely formatted in the discussion forum though!

{ "config": "aiscatcher", "version": 1, "receiver": [ { "input": "RTLSDR", "serial": "00000161", "rtlsdr": { "bandwidth": "192K", "biastee": false, "freqoffset": "0", "rtlagc": true, "sample_rate": "1536K", "tuner": "auto" } }, { "input": "rtltcp", "verbose": true, "rtltcp": { "protocol": "beast", "host": "127.0.0.1", "port": 30005 } } ] }

Thanks so much @jvde-github that's exactly what I needed!
Worked the first time.
I'm liking JSON config file.
I've dug deep looking for a full sample JSON config file, is there one (especially with some of the newer "features")?

[jvde-github]

Sorry, the closest I have is https://docs.aiscatcher.org/usage/json-configuration/ and then the rest of the documentation should provide details which fields are available.

Planning to include the JSON editor in the main program (and not separate control tool). But that takes some time and requires us to be a bit more strict on the schema.

Glad it works!

Would this be the correct syntax for Beast coming out a flightaware flight feeder. I have most of my config done today by the web interface and know I would have to move to JSON config only.

{
    "config": "aiscatcher",
    "version": 1,
    "receiver": [
        {
            "input": "rtltcp",
            "verbose": true,
            "rtltcp": {
                "protocol": "beast",
                "host": "(HOST IP)",
                "port": 30005
            }
        },
        {
            "input": "rtlsdr",
            "rtlsdr": {
                "tuner": "auto"
            }
        }
    ]
}

Looks good to me!

Can you point me at what I'm doing wrong here? I keep getting: Invalid JSON: invalid character '"' after object key:value pair

You need to add a comma after arrays, to indicate start of new key:value pair:

            }
        },
        {

You can validate JSON with for example this site: https://jsonlint.com.
This gives good error indications.

Thanks, I'm only passable when it comes to JSON.

[jason-a-alexander]

Ok got it working. That is cool as can be. Thanks
