AT+WIPCFG=4,0

Note: Free IP configuration parameters stored in non-

volatile memory

Notes

It is recommended to change the default settings of the WIP stack using +WIPCFG only when it is

required. Changing the parameter values especially the max number of sockets and the max TCP

buffer size with high values leads to over consumption of the stack memory which causes the

firmware to crash. Hence, care must be taken when the default settings of the stack is changed using

the +WIPCFG command.

The following option values set by the +WIPCFG command are taken into consideration at run time.

The option values below (except for AT_WIP_NET_OPT_PREF_TIMEOUT_VALUE and

AT_WIP_NET_OPT_ESC_SEQ_NOT_SENT) will be taken into consideration at the next start up only

if these are saved in non-volatile memory before stopping the stack.

 WIP_NET_OPT_IP_TTL

 WIP_NET_OPT_IP_TOS

 WIP_NET_OPT_IP_FRAG_TIMEO

 WIP_NET_OPT_TCP_MAXINITWIN

 WIP_NET_OPT_TCP_MIN_MSS

 WIP_NET_OPT_DEBUG_PORT

 AT_WIP_NET_OPT_PREF_TIMEOUT_VALUE

 AT_WIP_NET_OPT_ESC_SEQ_NOT_SENT

 AT_WIP_NET_OPT_AUTO_SWITCH
