Hi,
I would like to control my board with http page. I created test task:
void http_task(void *pvParameters) {
struct netconn *client = NULL;
struct netconn *nc = netconn_new(NETCONN_TCP);
// check alloocation socket
if (nc == NULL) {
ErrPrint("Failed to allocate socket\n");
vTaskDelete(NULL);
}
netconn_bind(nc, IP_ADDR_ANY, 80);
netconn_listen(nc);
char buf[512];
while (1) {
err_t err = netconn_accept(nc, &client);
if (err == ERR_OK) {
struct netbuf *nb;
if ((err = netconn_recv(client, &nb)) == ERR_OK) {
void *data;
u16_t len;
netbuf_data(nb, &data, &len);
InfoPrint("Received data: %d - %s", len, (char*) data);
snprintf(buf, sizeof(buf),
"HTTP/1.1 200 OK\r\n"
"Content-type: text/html\r\n\r\n"
"Test");
// odeslu page pryc
netconn_write(client, buf, strlen(buf), NETCONN_COPY);
}
netbuf_delete(nb);
}
InfoPrint("Closing connection");
netconn_close(client);
netconn_delete(client);
// necheme vsechen cas pro sebe
vTaskDelay(1);
}
}
And I call init here:
void Init_httpd(void) {
xTaskCreate(http_task, "http_server", 1024, (void*) NULL, HTTPD_TASK_PRIORITY, NULL);
}
And I have a problem. When I try to connect board from web browser, I get this output from my console.

Any idea, why is send RST?
I use: lwIP, FreeRTOS
And I have implement sntp client. And it works very well.
