I figured it out, I had the wrong URL path. Thank you.

Thanks, that also works for me.

How do I interpret the bin file that is returned by curl?

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.

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.

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

Hi,

[quote user=""]I can list the devices and query the state of the device, but I'm not sure how to progress[/quote]

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

[quote user=""]I've tried this path to access the GPS for example, but had no success:[/quote]

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
