Struggling to read data via REST-API with Thingy:91

[franz_btu]

Hello,

I'm trying to read data from the Thingy:91 via the REST-API. I can list the devices and query the state of the device, but I'm not sure how to progress.

So far I have used this to query the state of the device:

http api.nrfcloud.com/.../nrf-X Authorization:"Bearer Y"

I've tried this path to access the GPS for example, but had no success:

http api.nrfcloud.com/.../agps Authorization:"Bearer Y"

How can I get the sensor via the API?

Best regards, Franz

Hi,

 

I can list the devices and query the state of the device, but I'm not sure how to progress

This is good, means that the tokens etc. are in order.

I've tried this path to access the GPS for example, but had no success:

FetchDevice will give you the state of the device, however GPS data isn't stored in the shadow, so you will need to query the messages:

https://api.nrfcloud.com/v1#operation/ListMessages

 

Kind regards,

Håkon

Have you tried 'https' instead of 'http'  in your request?

Apologies,  I think I missed your real question.  The /location/agps endpoint requires a device identifier as a parameter: 

curl -G $API_HOST/location/agps -d "deviceIdentifier=$DEVICE_ID" -H "Authorization: Bearer $API_KEY" -H "Content-Type: application/octet-stream" -H "Range: bytes=0-2200" --output agps.bin

Please note: The just-released location services are designed to assist devices by providing additional 
information to the device about location. They do not provide a GPS location directly. That information is still
found by GET https://api.nrfcloud.com/v1/messages, if GPS is enabled in the application.

The single-cell endpoint (https://api.nrfcloud.com/v1/location/single-cell) provides the location of the 
cell tower matching the connection information passed in the parameters, along with an uncertainty radius.

The agps endpoint (https://api.nrfcloud.com/v1/location/agps) provides a binary payload that 
"Enables a faster time-to-first-fix (TTFF) for the GPS modem". It basically provides information
on satellite locations to help the GPS acquire a location fix faster.

So I tried the following:

http POST api.nrfcloud.com/.../messages \
  Authorization:"Bearer ..."

I only get the following answer:

Result code: 404
Not Found

I also tried the nrf Pizza demo, everything works there.
