#SH - Socket Shutdown
Parameter:
<connId> - socket connection identifier
1..6
Note: a socket connection can be closed only when it is in suspended mode
(with pending data too). Trying to close an active socket connection will
produce an error.
AT#SH=? Test command reports the range for parameter <connId>.
3.5.7.2.5. Socket Configuration - #SCFG
#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..5 - 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 – select automatically default value
1..1500 - packet size in bytes.
<maxTo> - exchange timeout( or socket inactivity time); if there’s no data
exchange within this timeout period the connection is closed
0 - no timeout
1...65535 - timeout value in seconds (default 90 s.)
<connTo> - connection timeout; if we can’t establish a connection to the
remote within this timeout period, an error is raised.
10..1200 - timeout value in hundreds of milliseconds (default 600)
<txTo> - data sending timeout; data are sent even if they’re less than max
packet size , after this period.
0 - no timeout
1..255 - timeout value in hundreds of milliseconds (default 50)
Note: these values are automatically saved in NVM.
AT#SCFG? Read command returns the current socket configuration parameters values
for all the six sockets, in the format:
#SCFG: <connId1>,<cid1>,<pktsz1>,<maxTo1>,<connTo1>,<txTo1>
<CR><LF>
. . .
#SCFG: <connId6>,<cid6>,<pktsz6>,<maxTo6>,<connTo6>,<txTo6>
