Question

Live Data is not streaming in the vuforia experience (Raspberry Pi Demo)

Hey ! I'm trying to implement the Raspberry Pi Demo as shown in (https://support.ptc.com/help/vuforia/studio/en/#page/Studio_Help_Center/RPAdvancedIntro.html#)

 

I completed every step as shown in demo but the Temperature and Memory Guage in the vuforia experience is not displaying the live value of the properties. Although It is continually refreshed in the ThingWorx Platform (RaspberryPiThing) but it is not displayed in the experience.  I've attached the screenshot of the preview of the vuforia studio experience. I've followed each step demonstrated in the setup. What am I missing here ?

Hi @Vinit31 ,

 

I could not remember this demo in detail, but the first thing what you need to check is if the value will go to thingworx thing property . So you need to check if the live data will change the property value in the RaspberryPiThing

So here we can first indetify where the issue is caused 

- the probelm could occurs in the remote connection of the thing /appkey , wrong IP etc

- or some permission issue for the Expierence Service setting

Hey, @RolandRaytchev  Thanks for reaching out. According to you, I should check if the live value is updated in the Thingworx Platform thing (RaspberryPiThing). I already mentioned in my query that it is updating live. The problem seems to be with the Vuforia Experience. I've attached the screenshot of the Thingworx Platform. You'll see the values of the properties of the Thing which get updated every time I hit refresh.

Hi  @Vinit31 ,

thanks for your feedback. OK some time when I skim over atext I could overlook some details. So that I am sorry if you have to repeat some think. 

So now - could you please, open you preview in debuging mode.

So in preview click Shift-Strg-I keys to go into debugging mode.

1.) so the first thing is to check what is the printing in your console windows. Are there any error message /mostly in red color) where we can see what is going wrong.

2.) second question is what kind if ES (experience service) do you use?

2.1)- on premises server hosted by your /your company 

2.2) - Experience service hosted by PTC cloud - commercial instance 

2.3) - Experience service hosted by PTC cloud - trail instance 

 

Also information about the used version will be helpful

to check it , please,  call in the chrome browser the  URL address of ES + /ExperienceService/properties/version

example:

https://xxxxXx.studio-trial.thingworx.io/ExperienceService/properties/version
e.g. returns: "8.3.8-b773"

For point 2.1)  it means the ES was hosted by you , also installed locally- in this case  we need to check the following setting- here I want to refer the Vuforia Studio Help. You need to check the required step if they are already done for your ES/TWX

 I .)Configure Public Access to ThingWorx

II.) Grant User Permissions    

Because for the PTC cloud server instances these steps are already done when the instance was installed but the cloud team. But for in premises instance this step are additional to the installation.
