Hello Gautham

The problem could be in your  broker setup. I have tested with "test.mosquitto.org" broker.

I am able to send data over mqtt successfully. Please find the code below which I have used for testing,

package main;
import platforms.xdk110;

setup ppWlan : WLAN{
	authentication=Personal(psk = "xxx" );
	ssid = "xxx";
}

setup ppMqtt : MQTT{
	transport = ppWlan;
	url = "mqtt://test.mosquitto.org:1883";
	clientId = "ppMQTT";
	var publishMsg = topic("hello/world");
}

every 100 milliseconds{
	print("Publish sensor data\n");
	ppMqtt.publishMsg.write("sensor data"); 
}

Able to connect to Mqtt broker successfully. Please find the test results below,
