This unsolicited response indicates the status of the created service.
<protocol>
<index>
This unsolicited response indicates an incoming connection is accepted on a TCP server socket
and the TCP client socket has been spawned.
<server index>
<client index>
spawned. This can be done using the <from idx> and <to idx> parameters. Note that the
value set for <to idx> should be equal or more than <from idx>.
It is not possible to create a client socket with AT+WIPCREATE=2, x, y, z when x is already
reserved by a server with AT+WIPCREATE=3,<server idx>,<local port>,a,b if one of the TCP
client sockets indexes between a and b is already reserved, be it by a client or a sever range.
The <from idx> and <to idx> are reserved for the server socket till the server socket and the
spawned sockets are closed explicitly. So when trying to create a new TCP server socket, the
<from idx> and <to idx> should be different from what was used earlier. A parameter used as
<from idx> can’t be used as <to idx> anymore for other TCP server socket creation until
spawned sockets with specified <from idx> and <to idx> are closed along with the TCP
server socket explicitly and vice versa.
When no more client indexes are available in the TCP server’s range (or no more resources
to accept new incoming connections), any peer trying to connect to the server will receive an
"accept" immediately followed by a shutdown (“peer close”).
