hi~~~，我测试发现。在smartconfig_ack.c 的方法sc_ack_send_task中我修改了这个方法。

static void sc_ack_send_task(void* pvParameters)
{
    sc_ack_t* ack = (sc_ack_t*)pvParameters;
    tcpip_adapter_ip_info_t local_ip;
    uint8_t remote_ip[4];
    memset(remote_ip, 0xFF, sizeof(remote_ip));
    struct sockaddr_in server_addr;
    socklen_t sin_size = sizeof(server_addr);
    int send_sock = -1;
    int optval = 1;
    int sendlen;
    int ack_len = (ack->type == SC_TYPE_ESPTOUCH) ? SC_ACK_TOUCH_LEN : SC_ACK_AIRKISS_LEN;
    uint8_t packet_count = 1;
    int err;
    int ret;
    int remote_port = 0;

    if (ack->type == SC_TYPE_ESPTOUCH) {
        remote_port = SC_ACK_TOUCH_SERVER_PORT;
    } else if (ack->type == SC_TYPE_ESPTOUCH_V2) {
        uint8_t port_bit =  ack->ctx.token;
        if(port_bit > 3) {
            port_bit = 0;
        }
        remote_port = SC_ACK_TOUCH_V2_SERVER_PORT(port_bit);
    } else {
        remote_port = SC_ACK_AIRKISS_SERVER_PORT;
    }

    bzero(&server_addr, sizeof(struct sockaddr_in));
    server_addr.sin_family = AF_INET;
    memcpy(&server_addr.sin_addr.s_addr, remote_ip, sizeof(remote_ip));
    server_addr.sin_port = htons(remote_port);

    esp_wifi_get_mac(WIFI_IF_STA, ack->ctx.mac);

    vTaskDelay(200 / portTICK_RATE_MS);

    while (s_sc_ack_send) {
        /* Get local IP address of station */
        ret = tcpip_adapter_get_ip_info(TCPIP_ADAPTER_IF_STA, &local_ip);

        if ((ESP_OK == ret) && (local_ip.ip.addr != INADDR_ANY)) {
            /* If ESP touch, smartconfig ACK contains local IP address. */
            if (ack->type == SC_TYPE_ESPTOUCH) {

            }

            send_sock = socket(AF_INET, SOCK_DGRAM, 0);

            if ((send_sock < LWIP_SOCKET_OFFSET) || (send_sock > (FD_SETSIZE - 1))) {
                ESP_LOGE(TAG,  "Creat udp socket failed");
                goto _end;
            }

            setsockopt(send_sock, SOL_SOCKET, SO_BROADCAST | SO_REUSEADDR, &optval, sizeof(int));

            if (ack->type == SC_TYPE_AIRKISS) {
