nRF9160: LTE Sensor Gateway

[Marshed]

I have managed to upload data from nRF52832 using nRF9160. I upload the data as tempreture sensor (although they are just values in mV), and my interface at the nRF connect for Cloud looks like this 

my questions are 

1. How can I change this interface? Instead of Temperature i want to use another label, for example voltage.
2. Are the data permanently stored in my cloud account? 
3. If they are, how can i retrieve them for further processing. 
4. Can I move the data to other website such as Microsoft Azure or Power BI?

please assist

Hi.

Have you seen the API documentation for nRF Cloud? You can find it if you log in to the cloud, and select "Device API" in the menu on the left side.

According to the API documentation, the messages are persisted indefinitely and can be retrieved using REST and GraphQL.

As it is possible to fetch the stored messages, it should be possible to access the data from other places. It is also possible to send the data directly to your own cloud service.

This link describes how to connect the nRF9160 to Google Cloud, and the nrf_cloud library can be used as a starting point for connecting to your own AWS instance.

Best regards,

Didrik

I have tried to use the link to connect the nRF9160 to Google Cloud, but whenever I compile the code i get this error 

undefined reference to `zepfull_private_der' in the gcloud.c 

any solutions?

The 

Authorization:"Bearer <API key>"

part of the httpie command is not part of the url, but specifies the content of the "Authorization" field in the HTTP header. For how to set this in MATLAB, you should refer to the MATLAB documentation.

here i can see that the maximum is 100, what if i want more than 100 what should i do?

In the response, there is a token for the next page of results, so that you can get more data.

However, I would also take another look at the design of your application to see if you really need to get all the data at once, or if you can get it in smaller chunks as the data becomes available.

[Marshed]

how do you use the token?

Similar to inclusiveStart and exclusiveEnd: <rest_of_url>&pageNextToken=<token>
