Receive Socket Status indicating closed connection

Finally, due to the "Connection" header in the request, the server should remotely close the
connection.
Field
Frame type
Socket ID
Status
Example Socket Status received from XBee indicating connection lost:
7E 00 03 CF 00 07 29
When Socket Status indicating a connection close is received, the socket ID will have been de-
allocated by the XBee and no further operations are possible or necessary using that ID.

Extended Socket example: UDP

UDP is connection-less, so this example demonstrates that a Socket Connect frame is not required to
begin communication and that multiple peers can be used with a single socket.
