#SI - Socket Info
<connId>
-
socket connection identifier, as before
<sent>
- total amount (in bytes) of sent data since the last time the socket
connection identified by
<connId>
has been opened
<received>
- total amount (in bytes) of received data since the last time the
socket connection identified by
<connId>
has been opened
<buff_in>
- total amount (in bytes) of data just arrived through the socket
connection identified by
<connId>
and currently buffered, not
yet read
<ack_waiting>
- total amount (in bytes) of sent and not yet acknowledged
data since the last time the socket connection identified by
<connId>
has been opened
Note: not yet acknowledged data are available only for TCP connections;
the value
<ack_waiting>
is always 0 for UDP connections.
Note: issuing
#SI<CR>
causes getting information about data traffic of all
the sockets; the response format is:
#SI: <connId1>,<sent1>,<received1>,<buff_in1>,<ack_waiting1>
<CR><LF>
…
#SI: <connId6>,<sent6>,<received6>,<buff_in6>,<ack_waiting6>
AT#SI=?
Test command reports the range for parameter
<connId>
.
Example
AT#SI
#SI: 1,123,400,10,50
#SI: 2,0,100,0,0
#SI: 3,589,100,10,100
#SI: 4,0,0,0,0
#SI: 5,0,0,0,0
#SI: 6,0,98,60,0
OK
Sockets 1,2,3,6 are opened with some data traffic.
For example socket 1 has 123 bytes sent, 400 bytes received,10 byte waiting to be read and
50 bytes waiting to be acknowledged from the remote side.
AT#SI=1
#SI: 1,123,400,10,50
OK
We have information only about socket number 1
3.5.5.2.3.
