2v06 ESP32 Static IP not available?

I guess this is what you are looking for:

// info about the structure 
typedef struct {
    ip4_addr_t ip;
    ip4_addr_t netmask;
    ip4_addr_t gw;
} tcpip_adapter_ip_info_t;


// STA calls
tcpip_adapter_dhcpc_stop(WIFI_IF_STA);
tcpip_adapter_set_ip_info(WIFI_IF_STA, const tcpip_adapter_ip_info_t *ip_info)

// AP - calls
tcpip_adapter_dhcpc_stop(WIFI_IF_AP);
tcpip_adapter_set_ip_info(WIFI_IF_AP, const tcpip_adapter_ip_info_t *ip_info)
tcpip_adapter_dhcpc_start(WIFI_IF_AP);
