@awwwwa 好的,感谢我试试

R128作为AP,电脑作为STA连接上R128的WIFI之后,
R128作为TCP的客户端,电脑作为TCP的服务端,在R128这边创建socket之后,进行connect的时候,一直连接失败,用wireshark抓包看,R128这边好像发不出任何TCP的数据包然后就返回connect失败了,
connect() 返回的错误码是103,
然后R128自己输出的LOG是 [WAR:1612]drop=1341, fctl=0x00d0.

电脑端IP地址:

tcp客户端连接代码:

void app_tcp_open_socket(char* ip_addr, uint16_t port)
{
    printf("[AppTcp] create a socket\n");
    tcp_sock = socket(AF_INET, SOCK_STREAM, 0);
    if (tcp_sock < 0) {
        printf("[AppTcp] Unable to create socket: errno %d\n", errno);
        return ;
    }

    tcp_dest_addr.sin_family = AF_INET;
    // tcp_dest_addr.sin_addr.s_addr = inet_addr(ip_addr);
    tcp_dest_addr.sin_port = htons(port);
    if (inet_aton(ip_addr, &tcp_dest_addr.sin_addr) == 0) {  
        printf("Error: Invalid server IP address\n");  
        close(tcp_sock);  
        return;  
    }  
    


    printf("[AppTcp] Socket created, connecting to %s:%d", ip_addr, port);
    int err = connect(tcp_sock, (struct sockaddr *)&tcp_dest_addr, sizeof(tcp_dest_addr));
    if (err != 0) {
        printf("[AppTcp] Socket unable to connect: errno %d\n", errno);
        return ;
    }
    printf("[AppTcp] Successfully connected");
}

@awwwwa LWIP找了几天,没有找到dhcp服务端获取已分配ip的例子,可以提供一个简单的例子吗?

@awwwwa wifi -l ap 这个指令我也试过了,它调用的就是wifi_ap_get_config()来获取,它返回的ap的地址是对的,但是返回的sta信息好像是mac地址,不是ip地址.
而且很奇怪,我明明只有一个设备连接,但是获取到的sta_num却有4个

R128的WIFI在AP模式下,其它设备连接这个WIFI,怎么在R128这边获取到分配给连接设备的IP地址呢?
官方的文档里没看到有提到具体方法,代码里水平有限也找不到接口
