Hi,

I need to find a way to update my Kura bundle[1] (deployed on RaspberryPi) remotely. I know the kura's web gui is works perfect but the point is, the device is not my network. Simply, I can't reach my device. But luckily, device can connect to the internet (mosquitto broker).

So, I thought that if I write another bundle[2] that listens specific mqtt-topic for my commands. And if I need to update bundle[1], I can talk my device via bundle[2] , update my bundle or change settings of Kura.

I want to hear your thoughts. Maybe I'm missing some point.

Thanks,
Said.

Hello Said,

Configuring Kura via MQTT is already supported in Kura. Take a look at this document [1] and let me know if you have any questions.

Hi Dave,

This document really saved my days. I took a look before but not completed, my bad Sad

Here what I understand. I need to write a bundle to control my all bundles in all devices. Simply I need "account_name" and "client_id" to send directives to device. But what I don't understand is, how can I set the topic name with my CloudClient instance? To make a request to this topic "$EDC/[account_name]/[client_id]/DEPLOY-V2/GET/download" in example. When I use my CloudClient's controlPublish method, it always add bundles name to topic. Without CloudClient, I don't know how to send KuraPayload object as a payload.

Thanks,
Said.

Hi again,

I made some progress today. I noticed Amit's application [1]. I tried to use DEPLOY-V2 to update deployment package but I didn't achieve.
Here is what i add to payload beyond request.id and requester.client.id;

payload.addMetric("dp.uri", "https://s3-us-west-2.amazonaws.com/dzmtzxbieb/terminator.dp");
payload.addMetric("dp.name", "terminator");
payload.addMetric("dp.version", "1.0.0");
payload.addMetric("dp.download.protocol", "HTTPS");

Here is the log;

2016-06-09 17:37:43,578 [MQTT Call: B8:27:EB:19:50:BC] INFO  o.e.k.c.c.CloudServiceImpl - Message arrived on topic: $EDC/test/B8:27:EB:19:50:BC/DEPLOY-V2/EXEC/download

Hello Said,

As you found out, the CloudClient will not work for this. If you want to use Kura you would need to use the DataService. This gives you complete control over the topic structure.

That said, there may be a bug in our documentation. Looking at the code, it appears two other fields are mandatory for the payload. Can you try adding these:

// Job ID, data type is long
payload.addMetric("job.id", "12345891011") ;
// System update, data type is boolean, set to false for now
payload.addMetric("dp.install.system.update", false);

Let me know if this works. If so, I will update the documentation and explain the addition properties.

Thanks,
--Dave

Hi Dave,

Thank you again for your help. I added "job.id" and it works now. You did a little typo, as you said the data type should be long, not string. And "dp.install.system.update" is a mandatory field also.

// Job ID, data type is long
payload.addMetric("job.id", 12345891011L) ;
// System update, data type is boolean, set to false for now
payload.addMetric("dp.install.system.update", false);

Thanks,
Said.

Hello Said,

Thanks for catching the typo! And yes, the dp.install.system.update is not required, it does have a default value. I will update the documentation to indicate the need for a "job.id" metric.

Hello,
I'm also trying to use the DEPLOY-V2 to update deployment package but when I'm sending MQTT call I'm getting no message at all. Also, I'm not getting any errors in the log as descriped in the above comments.

2016-10-15 20:35:50,003 [MQTT Call: raspberry] INFO  o.e.k.c.c.CloudServiceImpl - Message arrived on topic: EDC/guest/raspberry/DEPLOY-V2/EXEC/download

Since I'm using an MQTT broker that doesn't support $ in topic names, I have renamed the 'topic.control-prefix*' parameter to simply 'EDC' in the Kura web admins CloudService page. It looks like this works, as it appears that the call is arrived in the above log.
This is what I'm sending with the Kura MQTT client:

Topic: EDC/guest/raspberry/DEPLOY-V2/EXEC/download
Request ID: REQUEST_VE0US84QLJ3KLDS2HABCHVHC5D
Requester Client ID: CLIENT_90VKK2HU5LUKTM1SSPN8HSUDQT
Request payload:
dp.uri=https://s3-us-west-2.amazonaws.com/dzmtzxbieb/terminator.dp
dp.name=terminator
dp.version=1.0.0
db.download.protocol=HTTPS
job.id=121321
dp.install.system.update=false

I've also subscribed to 'EDC/guest/CLIENT_90VKK2HU5LUKTM1SSPN8HSUDQT/DEPLOY-V2/REPLY/REQUEST_VE0US84QLJ3KLDS2HABCHVHC5D', but there is no response there.
What I find strange is that I'm getting no error logs from CloudDeploymentHandlerV2. I have Kura 2.0.1 installed on my Pi2. Do you have any suggestion?

EDIT:
Trying to use the CONF-V1 service the same way.
After setting the Kura logger to debug, I'm getting this:

2016-10-15 21:38:04,931 [MQTT Call: raspberry] DEBUG o.e.k.c.d.t.m.MqttDataTransport - Message arrived on topic: EDC/guest/raspberry/CONF-V1/GET/configurations
2016-10-15 21:38:04,932 [MQTT Call: raspberry] DEBUG o.e.k.c.d.t.m.DataTransportListenerS - No registered listener services. Ignoring onMessageArrived

I don't understand, isn't this CONF-V1 is a default installed Kura service? Or I'm getting this entirely wrong.

Hello,
I thought I'm rephrasing my problem in some questions:
After I clean Install Kura and deploy any deployment package which is configurable, can I set it's configuration via MQTT call to the CONF-V1 service? Does this service should run and listen to MQTT calls by default? Does any configurable package which can be reconfigured also via GUI can be reconfigured via MQTT calls without any further development?

If you know the answers, any help or a simple yes/no would be greatly appreciated Smile

Hello,

Yes, all services running in Kura are available to be configured over MQTT. I am assuming you have reviewed: http://eclipse.github.io/kura/ref/mqtt-namespace.html . The section "Remote OSGi ConfigurationAdmin Interactions via MQTT" is the most relevant to what you are trying to do. Is this not working for you?

Thanks,

Yes, I'm trying to do this tutorial but doesn't seems to work. Using MQTT Client Utility, I'm publishing to EDC/guest/raspberry/CONF-V1/GET/configurations . I've changed "$EDC" to "EDC" in Kura web admin, and also set up the client-id and account name. I'm using an MQTT broker started on my local network. There is nor response on topic 'EDC/guest/CLIENT_LLR5FI9SEFKBN7SUGVB4MURSSU/CONF-V1/REPLY/REQUEST_PV4G16CEUIFDTFIQ82025E70VR' and here is the debug log of Kura:

Hello,

So the debug messages you posted seem okay, the CloudService is what will hold the registered listeners. Do you see something in the log after that? Below is an example of my test run. I have omitted account names and device IDs.

No, there is no such logs in my device. I've even searched for "Control Arrived on topic" message in my kura.log and there was no such result. Also I've never seen a log message about publishing to the REPLY topic (not even on DEBUG level).
I don't understand what I could be missing but it's have to be some basic stuff.
If I don't have any own cloudlet bundles installed, this still should work and return with an empty configuration list, right?

My service class declaration starts like:

public class MyService implements ConfigurableComponent, CloudClientListener
{ (...)

My OSGI component xml looks like:

<?xml version="1.0" encoding="UTF-8"?>

Hello,

I have created an issue here [1]. I hope we can get this resolved in the next release.

I can't speak to all brokers, but I know ActiveMQ and Eclipse Mosquitto can handle the '$'. If you want to try it out, Eclipse host a public Mosquitto broker at iot.eclipse.org:1883. I just tried and the '$' works on this broker.

Hi,

I am new to kura and I have been trying to remotely uninstall a deployment package using Amit's MQTT application[1], but I am unable to do so. This is the request payload I send from the application-

dp.name=hello_osgi

dp.version=1.0.0

I get the following error in the response topic-

Hello Dave,

My goal is to develop a web application capable of Remote OSGi DeploymentAdmin Interactions via MQTT, according to the assistance I got from the above mentioned link I am trying to achieve my goal by understanding how Amit's MQTT application [1] works and eventually start with my application accordingly.

While debugging Amit's application I have found out that code identifies the value of 'job.id' as String instead of long and sends it to kura and hence the error, as of now I am attempting to fix this bug.

So I have 2 questions-
Q1. Am I giving the input correctly in the application?
Q2. Is there a better approach to achieve my goal ?
