Usage

See examples/ for examples on how to use async_upnp_client.

upnp-client

A command line interface is provided via the upnp-client script. This script can be used to:

  • call an action

  • subscribe to services and listen for events

  • show UPnP traffic (–debug-traffic) from and to the device

  • show pretty printed JSON (–pprint) for human readability

  • search for devices

  • listen for advertisements

The output of the script is a single line of JSON for each action-call or subscription-event. See the programs help for more information.

An example of calling an action:

$ upnp-client --pprint call-action http://192.168.178.10:49152/description.xml RC/GetVolume InstanceID=0 Channel=Master
{
    "timestamp": 1531482271.5603056,
    "service_id": "urn:upnp-org:serviceId:RenderingControl",
    "service_type": "urn:schemas-upnp-org:service:RenderingControl:1",
    "action": "GetVolume",
    "in_parameters": {
        "InstanceID": 0,
        "Channel": "Master"
    },
    "out_parameters": {
        "CurrentVolume": 70
    }
}

An example of subscribing to all services, note that the program stays running until you stop it (ctrl-c):

$ upnp-client --pprint subscribe http://192.168.178.10:49152/description.xml \*
{
    "timestamp": 1531482518.3663802,
    "service_id": "urn:upnp-org:serviceId:RenderingControl",
    "service_type": "urn:schemas-upnp-org:service:RenderingControl:1",
    "state_variables": {
        "LastChange": "<Event xmlns=\"urn:schemas-upnp-org:metadata-1-0/AVT_RCS\">\n<InstanceID val=\"0\">\n<Mute channel=\"Master\" val=\"0\"/>\n<Volume channel=\"Master\" val=\"70\"/>\n</InstanceID>\n</Event>\n"
    }
}
{
    "timestamp": 1531482518.366804,
    "service_id": "urn:upnp-org:serviceId:RenderingControl",
    "service_type": "urn:schemas-upnp-org:service:RenderingControl:1",
    "state_variables": {
        "Mute": false,
        "Volume": 70
    }
}
...

You can subscribe to list of services by providing these names or abbreviated names, such as:

$ upnp-client --pprint subscribe http://192.168.178.10:49152/description.xml RC AVTransport

An example of searching for devices:

$ upnp-client --pprint search
{
    "cache-control": "max-age=3600",
    "date": "Sat, 27 Oct 2018 10:43:42 GMT",
    "ext": "",
    "location": "http://192.168.178.1:49152/description.xml",
    "opt": "\"http://schemas.upnp.org/upnp/1/0/\"; ns=01",
    "01-nls": "906ad736-cfc4-11e8-9c22-8bb67c653324",
    "server": "Linux/4.14.26+, UPnP/1.0, Portable SDK for UPnP devices/1.6.20.jfd5",
    "x-user-agent": "redsonic",
    "st": "upnp:rootdevice",
    "usn": "uuid:e3a17dd5-9d85-3131-3c34-b827eb498d72::upnp:rootdevice",
    "_timestamp": "2018-10-27 12:43:09.125408"
}

An example of listening for advertisements:

$ upnp-client --print advertisements
{
    "Host": "239.255.255.250:1900",
    "Cache-Control": "max-age=30",
    "Location": "http://192.168.178.1:1900/WFADevice.xml",
    "NTS": "ssdp:alive",
    "Server": "POSIX, UPnP/1.0 UPnP Stack/2013.4.3.0",
    "NT": "urn:schemas-wifialliance-org:device:WFADevice:1",
    "USN": "uuid:99cb221c-1f15-c620-dc29-395f415623c6::urn:schemas-wifialliance-org:device:WFADevice:1",
    "_timestamp": "2018-12-23 11:22:47.154293",
    "_address": "('192.168.178.1', 1900)",
    "_udn": "uuid:99cb221c-1f15-c620-dc29-395f415623c6",
    "_source": "advertisement"
}
