Failure to receive data from phone

Hello together,

I’m trying to follow the cumulocity tutorial, however I run into an issue:

I am not able to receive any measurements from my phone (tried multiple phones)

What I did:
Cumulocity Cockpit → Home → Connect Phone

I scan the barcore with the cumulocity app on my phone, my phone receives credentials and is logged in, however the dashboard says failure to register device.

The phone shows up under

Cumulocity Device Management → Groups → Phones

It is shown online, I have the app open, the sensors avtivated, I can manually send sensor alarms through the app and I can see them online.

But there is no device in Manage Devices - All Devices - no filters

I can’t choose any data points from the phone either.

Can someone point me to another way I can explore to resolve the issue?

Thank you in advance

Regards Jannik

Hi @Jannik

can you post a screenshot of the dashboard with the error and probably also the console log of the browser?

Which instance are you using? eu-latest? Which smartphone are you using? Android or iOS?

It’s weird that the phone shows up in the Cockpit but not in Device Management. Could mean that the device managed object wasn’t created correctly due to conflict or something.
Can you open the search in the top right of device management App and just search for *? What is listed there? If there are multiple phones you might want to delete them and try to re-register your phone.

Hi Jannik,

can you please specify the phone you’re using and which Android/iOS version is installed?
I assume the version of Sensor App is 1.2.x, correct?

Thanks,
Michael

Hi @Stefan and Michael and thank you for your fast reply.

I followed the Dashboard link to connect my phone. I scan the QR code and my phone gives all the green checkmarks it can.

The browser, however shows me

I am using the current cumulocity playstore version 1.2.0 on my Android 16 Google Pixel 7a

If with instance you mean the cumulocity setup, I do not know how it was set up since it’s supplied by our university. Is there somewhere I can look that up?

I cannot see any device in the device manager - all devices with no filters applied or when searching for *.

Is there something you could think of I could do?

If that helps with anything, there is a message when opening my groups, where I can locate the phone and hover over the connectivity icon.

double post because I can only embed one pic :slight_smile:

It translates to “currently no connection from server to client (not supported by device or connection problems)”

How long does it take to show all the green checkmarks in the app?
And is the browser still showing the progress animation in the “Waiting” button until this happens?

The app shows a successful login after 5 seconds, while the browser waits for 25 seconds to give me the error.
