### Class

# GUPnP Context

#### Description [src]

    class GUPnP.Context : GSSDP.Client {
      parent_instance: GSSDPClient
    }

Context object wrapping shared networking bits.

`GUPnPContext` wraps the networking bits that are used by the various GUPnP classes. It automatically starts a web server on demand.

For debugging, it is possible to see the messages being sent and received by setting the environment variable `GUPNP_DEBUG`.

Will set the new boot-id for this SSDP client. Does nothing if the UDA version used by the client is UDA 1.0

###### gssdp_client_set_config_id

The config-id is used to allow caching of the device or service description. It should be changed if that changes.

###### gssdp_client_set_network

Sets the network identification of `client` to `network`.

The network this client is currently connected to. You could set this to anything you want to identify the network this client is associated with. If you are using `GUPnPContextManager` and associated interface is a WiFi interface, this property is set to the ESSID of the network. Otherwise, expect this to be the network IP address by default.

###### GSSDP.Client:port
