connect 시 Sn_SR 값이 0x10 이 되는 경우 문의

TCP/IP Chip W5100

socket() 함수와 connect() 함수 사이의 delay 가 현상을 줄여주기는 합니다만 완벽하게 없어지지는 않습니다.

//create socket
ret = socket(CLIENT_SOCKET, Sn_MR_TCP, localPort++, 0);
if(localPort == 0xFFFF) {
	localPort = 50000;
}

if (ret < 0) {
	HAL_GPIO_TogglePin(LED_RED_GPIO_Port, LED_RED_Pin);
	printf("socket failed{%ld}.\n", ret);
	close(CLIENT_SOCKET);
	osDelay(500);
	continue;
}

osDelay(20);

//connect to the server
ret = connect(CLIENT_SOCKET, serverIP, SERVER_PORT);
if (ret < 0) {
	HAL_GPIO_TogglePin(LED_RED_GPIO_Port, LED_RED_Pin);
	printf("connect failed{%ld}.Sn_SR()={%d}\n", ret, getSn_SR(CLIENT_SOCKET));
	close(CLIENT_SOCKET);
	osDelay(500);
	continue;
}
