工业互联项目2MQTT未能连上ONENET

想请教各位大佬还有韦老师的团队，使用工业互联项目2的MQTT代码，修改了一下，想连接ONENET，发现TCP连接成功，MQTT连接不成功，使用MQTTX连接是可以的，想问一下这是因为什么呢
static void test1(void)
{
int subsqos = 2;
Network n;
MQTTClient c;
int rc = 0;

int wait_seconds;

NetworkInit(&n);

while (0 != NetworkConnect(&n, PC_MQTT_BROKER_IP, PC_MQTT_BROKER_PORT))
{
	Draw_String(0, 64, "Re-Connect TCP/Port ...", 0xff0000, 0);
	vTaskDelay(100);
}

MQTTClientInit(&c, &n, 1000, buf, 100, readbuf, 100);

	Draw_String(0, 96, "Re-Connect MQTT Broker ...", 0xff0000, 0);
}

Draw_String(0, 96, "MQTTSubscribe ...", 0xff0000, 0);
rc = MQTTSubscribe(&c, sub_topic, subsqos, messageArrived);

while (1)
{
	memset(&pubmsg, '\0', sizeof(pubmsg));
	sprintf(pubbuf, "msg from H5, %d", cnt++);
	pubmsg.payload = pubbuf;
	pubmsg.payloadlen = strlen(pubbuf);

	rc = MQTTPublish(&c, pub_topic, &pubmsg);
	
	  /* wait for the message to be received */
	wait_seconds = 10;
	while (wait_seconds-- > 0)
	{
		MQTTYield(&c, 100);
	}
	
}
