The SimpleLink device can return a list of peer services, which are stored in the device, without issuing any queries (relying on previously collected data stored in the cache). The list is in a form of a service structure, which can include full-service parameters with text, partial-service parameters, or short-service parameters (port and IP only), dedicated for hosts with memory limitations (for different size of buffers). The list size can store up to eight services, and when a new service is discovered, the oldest service entry is replaced. The list is cleared when mDNS service is disabled or if Wi-Fi disconnects.

The host can retrieve different levels of detail to support memory reduction in the host application:

• IPv4/IPv6 full-service parameters – IP address, port, service name, service host, and service text
• IPv4/IPv6 partial-service parameters – IP address, port, service name, and service host
• IPv4/IPv6 minimal-service parameters – IP address and port only

Example:

_i16 Status;           
SlNetAppGetShortServiceIpv4List_t  listMdns[6];
 /* Get a list of discovered services */
Status = sl_NetAppGetServiceList(0, 6, /* Maximum number of services to receive */
         SL_NETAPP_FULL_SERVICE_WITH_TEXT_IPV6_TYPE, /* receive full ipv6 services with text */
         (_i8*) &listMdns6[0], sizeof(listMdns));
if( Status )
{
    /* Error */
}
