tcp_client例程为何去掉发送后，一直接收就会容易出现数据粘包

[fatcatLA]

Code: Select all

while (1) {
            //int err = send(sock, payload, strlen(payload), 0);
           // if (err < 0) {
             //   ESP_LOGE(TAG, "Error occurred during sending: errno %d", errno);
             //   break;
           // }

            int len = recv(sock, rx_buffer, sizeof(rx_buffer) - 1, 0);
            // Error occurred during receiving
            if (len < 0) {
                ESP_LOGE(TAG, "recv failed: errno %d", errno);
                break;
            }
            // Data received
            else {
                rx_buffer[len] = 0; // Null-terminate whatever we received and treat like a string
                ESP_LOGI(TAG, "Received %d bytes from %s:", len, host_ip);
                ESP_LOGI(TAG, "%s", rx_buffer);
            }

            vTaskDelay(2000 / portTICK_PERIOD_MS);
        }

代码如下，当我使用tcp_client例程，并且把发送数据注释掉，再接收数据就很容易出现TCP数据粘包，求助

这两者应该没有直接的关联，TCP 粘包总是会存在的。你可以启用 socket option TCP_NODELAY 来避开 TCP 粘包
