MqttException when receiving commands via IotDevice

[James Cancilla <ca...@gmail.com>]

Hello,


I have Quarks running on an Android application. The application is setup
similar to the following:

DirectProvider dp = new DirectProvider();
Topology t = dp.newTopology("Monitor");

TStream<MyData> jsonStream = ...

IotDevice device = new IotfDevice(t, getIotfOptions());
device.events(jsonStream, IOTF_EVENT_ID, QoS.FIRE_AND_FORGET);

device.commands("viz").print();

dp.submit(t);


When I run the Android app, the events are successfully published to IoT
but I am unable to receive any commands from IoT. The Android logcat is
filled the following messages/exception:

I/LoggerUtility: MQTT Call: d:my_org_id:my_device_type:my_device_id:

Any thoughts as to what the problem may be?

Thanks,

It’s not an area I’m particularly familiar with but in hopes of gaining a toehold I tried a simple search of the current Watson IoT Platform code and couldn’t find any of those messages.

I see that quarks has version 0.0.9 of the library (connectors/iotf/ext/com.ibm.iotf.client-0.0.9.jar) and it’s now up to 0.0.11 (https://github.com/ibm-messaging/iot-java/releases <https://github.com/ibm-messaging/iot-java/releases>).  maybe try pulling and using that to quickly see if it helps?  if not maybe the post a question/issue to that project to see if they can provide some clues.

@djd has all of the experience with this connector.
