#SI - Socket Info

#SI: <connId>,<sent>,<received>,<buff_in>,<ack_waiting>

where:

- 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>

…

#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

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

1 2 ... 239 240 241 242 243 244 245 246 247 248 249 ... 317 318
