Re: [kapua-dev] Kura Connection Status

[Alon Harel <alonhrl.us@xxxxxxxxx>]

Hi,

I have actually the same problem, I'm running the Kapua demo script and Kura emulator from eclipse. I have configured Kura with the MQTT broker and the Kura status shows connected. I also can see MQTT messages from Kura to Kapua. On the Kapua side though, I don't see any indication of this Kura device at all.

Frank, you wrote you see it is listed in Kapua. Did you have to do any configuration on the Kapua side to make that happen?

Did you find a way to make Kapua understand Kura is connected?

Any help will be much appreciated.

Thanks,

Alon

Hello everyone,

I'm new to the whole Kapua/Kura framework and so far I got a RaspberryPi with Kura up and running. I then used the demo-box of Kapua to evaluate it. As far as I can tell, everything was set up as per the readme. I didn't get any error messages and I got the web console working nicely.

After configuring the correct broker for the Kura device and connecting it to the Cloud, I was able to get my device listed in Kapua.

However, I am stuck at determining what else I have to do to make Kapua understand that the device is actually live and connected. The connection status remains DISCONNECTED, despite the Kura device sending MQTT data messages and being connected to the cloud/broker. On the Kura side-of-things everything looks fine with a green CONNECTED status.

I have not added any custom packages to Kura yet, just running the provided Heater sample to generate data messages. I assume that Kura itself should take care of the MQTT keep-alive process (particularly, since the timeouts, etc. are configured for the MqttDataTransport).

What am I missing here? Is there any additional information I can provide you with to help find the cause of this problem?

I tried this with Kura 2.0.2 on a Raspberry Pi 2 against the current master of Kapua (0.2.0-SNAPSHOT).

Best regards,
