Joins the multicast group specified by [code]multicast_address[/code] using the interface identified by [code]interface_name[/code].
|
|
You can join the same multicast group with multiple interfaces. Use [method IP.get_local_interfaces] to know which are available.
|
|
Note: Some Android devices might require the [code]CHANGE_WIFI_MULTICAST_STATE[/code] permission for multicast to work.

|
Makes this [PacketPeerUDP] listen on the [code]port[/code] binding to [code]bind_address[/code] with a buffer size [code]recv_buf_size[/code].
|
|
If [code]bind_address[/code] is set to [code]"*"[/code] (default), the peer will listen on all available addresses (both IPv4 and IPv6).
|
|
If [code]bind_address[/code] is set to [code]"0.0.0.0"[/code] (for IPv4) or [code]"::"[/code] (for IPv6), the peer will listen on all available addresses matching that IP type.
|
|
If [code]bind_address[/code] is set to any valid address (e.g. [code]"192.168.1.101"[/code], [code]"::1"[/code], etc), the peer will only listen on the interface with that addresses (or fail if no interface with the given address exists).

Enable or disable sending of broadcast packets (e.g. [code]set_dest_address("255.255.255.255", 4343)[/code]. This option is disabled by default.
|
|
Note: Some Android devices might require the [code]CHANGE_WIFI_MULTICAST_STATE[/code] permission and this option to be enabled to receive broadcast packets too.
