connection produce an error and to close a closed socket or a listening socket
produce
OK

AT#SH=?
Test command reports the range for parameter
<connId>
.
#SCFG - Socket Configuration
AT#SCFG=
<connId>,<cid>,
<pktSz>,<maxTo>,
<connTo>,<txTo>
Set command sets the socket configuration parameters.
Parameters:
<connId>
- socket connection identifier
1..6
<cid>
- PDP context identifier
1 - numeric parameter which specifies a particular PDP context definition
<pktSz>
- packet size to be used by the TCP/UDP/IP stack for data sending.
0 - automatically chosen by the device.

<maxTo>
- exchange timeout( or socket inactivity time); if there’s no data

0 - no timeout
n
- timeout value in seconds (default 90 s.)
<connTo>
- connection timeout; if we can’t establish a connection to the remote

Note: these values are automatically saved in NVM.
