_u8 outLen =
sizeof
(SlNetAppDhcpServerBasicOpt_t);
dhcpParams.lease_time
= 4096;
// lease time (in seconds) of the IP
Address
dhcpParams.ipv4_addr_start =

// first IP Address for allocation
dhcpParams.ipv4_addr_last
=
SL_IPV4_VAL(192,168,1,16);
// last IP Address for allocation.
Status
= sl_NetAppStop(SL_NETAPP_DHCP_SERVER_ID);
// Stop DHCP server before
settings
if

// error
}
Status
= sl_NetAppSet(SL_NETAPP_DHCP_SERVER_ID, SL_NETAPP_DHCP_SRV_BASIC_OPT, outLen, (_u8*

// error
}
Status
= sl_NetAppStart(SL_NETAPP_DHCP_SERVER_ID);
// Start DHCP server with new

DNS Server
The SimpleLink device has an internal DNS server which runs in AP mode and Wi-Fi Direct mode (GO).
The DNS server is enabled by default and can be disabled. The DNS server resolves the SimpleLink
device IPv4 address. The default domain name is
mysimplelink
and it can be configured.
Example:
_i16 Status;
Status
= sl_NetAppStop(SL_NETAPP_DNS_SERVER_ID);
// Stop DNS server
if
( Status )
{
// error
}

IPv4 interface is available for
traffic. The event includes IPv4
parameters such as gateway
mask and DNS server address.
After Wi-Fi connection, two
options:
• Immediate event: static
configuration or DHCPv4
opportunistic renew
configuration.
• Delay between the
connection and the event:
DHCPv4, DHCPv4, fast
renew or LLA.
