#SD - Socket Dial
effect (if used) for TCP connections.
Note: if we set
<connMode>
to
online mode connection
and the command is
successful we enter in
online data mode
and we see the intermediate result code
CONNECT
. After the
CONNECT
we can suspend the direct interface to the
socket connection (nb the socket stays open) using the escape sequence (
+++
): the
module moves back to
command mode
and we receive the final result code
OK
after the suspension. After such a suspension, it’s possible to resume it in every
moment (unless the socket inactivity timer timeouts, see
#SCFG
) by using the
#SO
command with the corresponding
<connId>
.
Note: if we set
<connMode>
to
command mode connection
and the command is
successful, the socket is opened and we remain in
command mode
and we see the
result code
OK
.
Note: if there are input data arrived through a connected socket and not yet read
because the module entered
command mode
before reading them (after an escape
sequence or after
#SD
has been issued with
<connMode>
set to
command mode
connection)
, these data are buffered and we receive the
SRING
URC (
SRING
presentation format depends on the last
#SCFGEXT
setting); it’s possible to read
these data afterwards issuing
#SRECV
. Under the same hypotheses it’s possible to
send data while in
command mode
issuing
#SSEND
AT#SD=?
Test command reports the range of values for all the parameters.
Example
Open socket 1 in online mode
AT#SD=1,0,80,”www.google.com”,0,0,0
CONNECT
…
Open socket 1 in command mode
AT#SD=1,0,80,”www.google.com”,0,0,1
OK
3.5.5.2.8.
Socket Accept - #SA
#SA - Socket Accept
AT#SA=<connId>
[,<connMode>]
Execution command accepts an incoming socket connection after an URC
SRING:
<connId>
Parameter:
<connId>
- socket connection identifier
1..6
<connMode>
- Connection mode, as for command
#SD
.
0 - online mode connection (default)
1 - command mode connection
