Acquiring PGPS data using a proxy server

Hello,

[quote user="Sirjee"]HI, I have read the Cloud to Cloud setup, it explains what the proxy server should do, but not what the nrf9160 device should do differently when connecting via a proxy server.[/quote]

The documentation does not address the device side, because that is entirely up to the you. Cloud-to-cloud means that the device will connect to your cloud, not nRF Cloud. Their cloud could be anything -- Azure, AWS, or what have you.

What the device side does need is some way for your device/cloud interface to request P-GPS data with parameters provided by the P-GPS library, and then once data is received, for the device to download and utilize the P-GPS data.

This is explained here:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/libraries/networking/nrf_cloud_pgps.html#configuration

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/libraries/networking/nrf_cloud_pgps.html#transport-mechanisms

look at CONFIG_NRF_CLOUD_PGPS_TRANSPORT_NONE -- this allows the you to provide a custom interface for sending the P-GPS parameters to your cloud and for receiving from your cloud the hostname and path to the P-GPS binary data; your cloud would obtain that using its proxy to the nRF Cloud P-GPS service
look at CONFIG_NRF_CLOUD_PGPS_DOWNLOAD_TRANSPORT_CUSTOM vs. CONFIG_NRF_CLOUD_PGPS_DOWNLOAD_TRANSPORT_HTTP -- these let the you select how the actual P-GPS binary data will be downloaded to the device; if your cloud service provides a hostname and path to the file on your server, you can use CONFIG_NRF_CLOUD_PGPS_DOWNLOAD_TRANSPORT_HTTP; otherwise, you need to use _CUSTOM and implement that interface yourselves.

[quote user="Sirjee"]A follow up to my previous question, what should the HTTP header look like, in terms of the JWT Bearer authentication that is used when its a direct cloud to cloud.[/quote]

Here is our documentation to what JWTs should look like in the header

Kind regards,

Hello Sirjee ,

My answer does not seem to be visible in the public view. Can you please verify that you have seen this message?

[quote user=""]I tried searching in the documentation and online, but nothing seems to be clear as to how this will work.[/quote]

In what documentation have you searched? Have you looked at the nRF Cloud documentation on Location Services?

Do you want your server to connect to nRF Cloud in order to use Location Services? If so, have a look at the Cloud to Cloud setup documentation.

Hi it would be nice to get a response to my request above, repeated here.

What changes should be made in the rest api code to connect through a proxy server to retrieve AGPS and PGPS data.

Thanks

We are very close to production and I want to make little changes as possible.

Also I have just taken this project over, and it is not not clear at the moment as to how I move to v2.3.0 without making too many changes.

Are the devicetree structure compatible etc.

What changes are required to move to v2.3.0, I would actually prefer that if the changes are minimal risk to my deliverables.

Thank you.

Hello,

I will have a look into your case. Could you please elaborate more on exactly how your application will work? Is there a reason for using nRF Connect SDK v1.9.0? Current version is at v2.3.0 and includes more fixes, etc.

Kind regards,
Øyvind
