MQTT Arduino PubSubClient Bluemix

[Dale Angus]

I am trying to publish to my IoT platform in Bluemix. I have a Bluemix app that confirms that the clients, node-RED, Eclipse Paho, Apache Quarks, Python are all working.

But can't publish with Arduino PubSubClient somehow. It doesn't even work with quickstart.messaging.internetofthings.ibmcloud.com

I am using the sample ino from an IBM developerWorks article.

Here are some lines of code
//char servername[]="quickstart.messaging.internetofthings.ibmcloud.com"; does not connect

char servername[]="pzd5t6.messaging.internetofthings.ibmcloud.com";
String clientName = String("d:pzd5t6:MqttClient:aabbccddee");
String topicName = String("iot-2/evt/eid/fmt/json");

PubSubClient client(servername, 1883, 0, ethClient);
client.connect(clientStr, "use-token-auth", "xxx");   
boolean pubresult = client.publish(topicStr,jsonStr);


Here's the output from Serial Monitor
attempt to send {
"d": {
"myName": "Arduino DHT11",
"temperature (F)": 87,
"temperature (C)": 30,
"humidity": 22
}
}
to iot-2/evt/eid/fmt/json
unsuccessfully sent

Any ideas?

Problem solved. Increased the MQTT_PACKET_SIZE from default 128 to 256.

You are right Dale.

I was stuck on this issue until I discovered your post.

Thanks, Dale!

will try to remember to get back with you when I'm back from vacation.  Just to make sure I get this right.  You're wanting to Publish or Subscribe with an Arduino client?  If that is correct, I may be able to help.
