How to Find Out "mqttBrokerPassword" in Airvantage?

Wavefront_yk · May 10, 2017, 9:49pm

Hi,

I am trying to install “sensorTOAirVantage” app in my mangOH board, but ran into error to start the app. I wonder if there is instructions to find out “mqttBrokerPassword”.

root@swi-mdm9x15:~# config get sensorToAirVantage:/
/
mqttBrokerHost == eu.airvantage.net
mqttBrokerPort == 1883
mqttBrokerPassword == ???

Thanks
YK

Hi YK,

login to airvantage
Select Monitor > Systems from the drop-down menu
Click on your system name
In the top right, click More > Edit
Under “Application” you should see the name of the application model for the application you are trying to run.
Next to the application, there is a lock icon. If you click that icon, you will be prompted with a dialog that will allow you to either view or set the password.

If you don’t have the application model registered with that device record in AirVantage, then you will need to follow these steps:

On the edit screen of the device, click the search (magnifying glass) icon next to the “Applications” section
Search within the dialog to find the application model that you want.

If the application model you want is not found in that dialog, then it may need to be loaded into AirVantage. Follow these steps:

Click Develop > My Apps
Click the Release icon (an upward facing arrow)
Click the “Select a file” button and browse to the appropriate zip file. AirVantage expects a zip file that contains a .app file. Here are some examples of .app files.
From the “Advanced Settings” section of the dialog, choose “Publish”

If you want more detailed information on the application model, here is the reference

Let me know if anything was unclear.

Thanks for your detailed information. Really appreciated.

I could not see “unlock” next to my application.
Not sure if I doesn’t build my .app correctly. I built my app using “av-pack” command:
av-pack -u helloWorld.wp85.update -b _build_helloWorld/wp85 -t abcCo.jsmith.helloWorld from:
http://legato.io/legato-docs/latest/howToAVConnect.html

I will go through your instructions carefully to building the .app and see if it makes any difference.

Try just putting the .app file in a .zip file and uploading that instead of using av-pack.

Wavefront_yk · May 19, 2017, 11:25pm

Thanks David!

I have successfully built the .app and uploaded into the AirVantage and I can see the icon and set the password.

But when I start the app, connection seems published but failed on “getaddrinfo” and then connection get lost. Could you please advise if anything that I missed?

Rather than running the demo application, try to run cm data connect from the command line. That should establish a data connection. Once the connection is established, try to ping a few well known hosts like google.com (and mangoh.io ). I just want to verify that hostname resolution is working properly and that the problem is specific to the mqtt use case.

Wavefront_yk · May 20, 2017, 12:08am

data is connected. I also tried to stop and start…

Also, I can start and stop helloWorld app from AirVantage.
