SpotPass: Difference between revisions

Line 3:

SpotPass Internet communications are mostly small UDP frames and HTTPS transfers, the only HTTP download is the connection test page.

With the [[2.0.0-2]] update, SpotPass now regularly requests content over HTTPS from nppl.c.app.nintendowifi.net and sometimes nasc.nintendowifi.net. These are probably related to the SpotPass automatic software download functionality. Going by the domain names, nppl* might be for SpotPass software downloads?

In System Settings, you can disable SpotPass automatic title downloading,(this is _only_ for free titles etc not auto system updates) but it states that important software will still downloaded.

In System Settings, you can disable SpotPass ~~content~~ downloading,(this is _only_ for free titles etc not auto system updates) but it states that important software will still downloaded~~. This is likely why SpotPass still connects to nppl* even with that option disabled~~.

'nasc.nintendowifi.net' confirmed usages:

*Friends List application requires this server to be 'Online' (most likely the reason for regular requests to this server)

*Required for initialization of E-shop, (for first time e-shop users). Not required for using E-Shop after first use.

nppl.c.app.nintendowifi.net is used to download various data via HTTPS, including a cleartext xml policylist which is country-code specific. This policylist seems to contain a list of SpotPass tasks for certain titles. This policylist can control whether the specified tasks are processed at all.

== Homemenu SpotPass usage ==

Line 16:

Homemenu uses two domains with HTTPS for SpotPass. SpotPass stores this content in Homemenu's NAND shared extdata.

* Via the a248.e.akamai.net cache mirror npdl.c.app.nintendowifi.net is accessed~~. The content(using the SpotPass content container) downloaded from this seems to be related to notifications possibly~~. There's 4 files download from here, each of which are downloaded if updated every 24 hours. There's separate files stored on the server for each region and language.

* Via the a248.e.akamai.net cache mirror npdl.c.app.nintendowifi.net is accessed. There's 4 "bashoX" files download from here,(where X is 0-3) each of which are downloaded if updated every 24 hours. There's separate files stored on the server for each region and language.

* The pls.c.shop.nintendowifi.net domain is used for uploading data from the NAND shared extdata. "pl" might be referring to "play log"? This is uploaded every 24 hours.
