Example: Accepting / Rejecting Socket Connection Request From Remote Client - Siemens Brodersen MC55 AT Command Manual

10.5.1 Example: Accepting / Rejecting Socket Connection Request
from Remote Client
Host 1 configured as Socket listener with IP address 10.10.0.187 at port 65534 is receiving a connection request
from the remote client 10.10.0.185 (at port 1024). The example assumes that connection and service profiles
have been created as stated earlier.
Start the Socket service in listener mode, then query the IP address dynamically assigned to the Socket listener:
at^siso=4
at^siso?
^SISO: 0, ""
^SISO: 1, ""
^SISO: 2, ""
^SISO: 3, ""
^SISO: 4, "Socket","3","3","0","0","10.10.0.187:65534","0.0.0.0:0"
^SISO: 6, ""
^SISO: 7, ""
^SISO: 8, ""
^SISO: 9, ""
OK

Host 1 opens the Socket service.
Query the current status of all services. All service
profiles are unused, except for service profile 4
which is running
<srvState>=3 (listening) and <socketState>=3
(LISTENER). The response also indicates the IP
address dynamically assigned to the listener. The lis-
tener's access data (IP address and TCP port num-
ber) shall be passed on to the client.
The URC indicates that the listener configured on
service profile 4 is receiving a Socket connection
request (<urcCause>=1) from the remote client.
The last URC parameter
the ID of the dynamically assigned service profile,
here 0.
Query the current status of services.
Indication on host 1 that the connection request from
the remote client has been dynamically assigned to
service profile 0 which is set to Server mode
(<socketState>=4).
Host 1 accepts the connection request, where 0 is
the ID of the dynamically assigned service profile.
The URC indicates that data transmission to the
remote client is possible. If the remote client has
already sent some data the additional URC ^SISR:
0,1 is displayed.
Query the current status of services.
The socket connection between host 1 and remote
client is successfully established.
