Private SUPL Server or Nordic?

[seludeft]

Hi,

I see from the code in GitHub:

https://github.com/NordicPlayground/fw-nrfconnect-nrf/blob/master/samples/nrf9160/gps/src/supl_support.c

#define SUPL_SERVER      "supl.google.com"
#define SUPL_SERVER_PORT 7276

That the new A-GPS is using google's SUPL server. 

Since google is like "The Borg" (Star Trek reference) / "Big brother" ... tracking everything about all users using their servers .. it is a bit unacceptable that all the billions of IOT devices we (all) will create, shall by default be tracked by google.

Since we want to provide "100% Privacy" in our IOT devices we are creating, is it possible to run our own SUPL server? And if so, could you provide some more information regarding this procedure?

Also, maybe Nordic could instead begin running their own SUPL server? for allowing quick testing of IOT.

How about setting up a proxy server?
For example with https://github.com/tajuma/supl/blob/master/src/supl-proxy.c

Not sure if the IMSI is included with the Nordic SUPL client library.
With this proxy you can find out and possibly strip/replace the problematic information from the request.

Let us know ...

Hi Martin,

Maybe you can be more anonymous if you are using a proxy.  

Regarding IMSI: The GPS sample is using the IMSI as the Device ID when initiating a SUPL session with the server. It seems to be an option to replace this one using IP address instead.

If you want to test the SUPL, you have to a public available SUPL server.

What has been made is an alternative solution (proper documentation is WIP)
