Help for Azure IoT Hub Connector Demo Issue

[DavidShen]

Hello everyone,

I'm try to practice the Azure IoT Hub Connector, I follow the guide at http://support.ptc.com/help/thingworx_hc/thingworx_cx_services/#page/thingworx_cx_services%2Fazure_connector%2Fc_azure_connector_hc_top_level_page.html%23 , the connector service is work as well.

but when I try the next step to launch the "Edge Device Demo", I got error as below. can anyone help me to identify the problem?

Hi, David.

Can you tell me just a bit more about your setup; like what version of ThingWorx and what DB you are using? I'm going to follow the same procedure and see if I can reproduce the error.

Thanks!

[DavidShen]

Hi Craig,

Tanks for your respond,

The environment is ThingWrox 8.1 with H2 DB on windows7.

Thanks!

David

[CRArko]

Okay, it will take me a bit to set up a test system, but then I'll walk through the documented process and see if I get the same error.

[DavidShen]

Thanks, Craig,

these more information is when I just launch the Azhre IOT Hub Connector( still not run the edge demo), the TWX report a issue:Could not dispatch async service request [NotifyPropertyUpdate] : Service not implemented. more detail please reference the attachment.

[ShengLiangQiu · Accepted solution]

Seems a bug of the Groovy JsonBuilder of Azure IoT Connector 2.0, I have recompiled the code and please unzip attachment and copy the jar file to replace the same one under demo\edge-device-demo\lib, everything is OK.

[DavidShen]

Hi Chris,

Thank you very much!

Everything is OK now!

Hi,

Whenever I am running the windows bat file edge-device-demo.bat after setting environment variable EDGE_DEVICE_DEMO_OPTS="-Dconfig.file=../conf/edge-device.conf" I am getting below error 

Error: Could not find or load main class C:\ThingWorx-Azure-IoT-Hub-Connector-2-0-0\Thingworx-Azure-IoT-Hub-Connector-2.0.0.141\demo\edge-device-demo\conf\edge-device.conf

Please let me know what I am doing wrong here.

Thanks,

Azim

You may put the parameter in the bat file like below to see if it works or not:

@rem Add default JVM options here. You can also use JAVA_OPTS and EDGE_DEVICE_DEMO_OPTS to pass JVM options to this script.
set DEFAULT_JVM_OPTS=
set EDGE_DEVICE_DEMO_OPTS=-Dconfig.file=C:\Working\AzureIoTConnector200\demo\edge-device-demo\conf\edge-device.conf
@rem Find java.exe
if defined JAVA_HOME goto findJavaFromJavaHome

I got past the same error but I don´t see the values refreshing in the Thing I´ve created, 

this is what I see from the edge-device-demo:

13:00:10.724 [pool-3-thread-1] INFO c.t.p.a.i.d.AzureIotEdgeDeviceDemo - Send e
vent response: status=OK_EMPTY, context={}

Is this correct?, why is it not updating the values? any help?

[ShengLiangQiu]

Please make sure that you follow the azure IoT connector guide strictly first, then if you happen to see:

Exception in thread "main" groovy.lang.MissingMethodException: No signature of m
ethod: java.lang.Long.call() is applicable for argument types: (java.lang.Long)
values: [2]

in the client console, then use the zip file I posted, unzip it and copy the azure-iot-edge-demo-2.0.0.141.jar file  to replace the original one (remember to backup first), then restart the client, it should be OK. Otherwise please provide the log file for further debug.

@ShengLiangQiu,

Could you explain more for your building tools?

Are you also using the Groovy JsonBuilder with a different version?

This will help us understand more for the issue and note it down in our knowledge base.

Thanks,

Anna

Anna, the building tool is eclipse, groovy-all-2.4.5.jar to build the new version.
