So here's a question that may just be me not knowing how the Streetpass Mii Plaza works, but every now and then when I use Net Pass I get some new visitors, but then I also see that some other Miis in the plaza that I had in there earlier say they were encountered 1 minute ago, but I still only have one tag from them. Is this a quirk of Mii Plaza or is it something to do with Net Pass? So far I haven't gotten more than 1 tag on any Mii met with Net Pass.
I think this is another one of the same things happening to me with nintendogs and with everyone on tomodachi life- in nintendogs, when I see the people I streetpassed on walks they always introduce themselves like it’s the first time. I also think I recall seeing people I saw before in the plaza as new miis but thought I was just imagining it lol

I have an idea (that was already mentioned by superdude so I cant really take full credit)

Streetpass. IDs.
The first/next time a user opens the app, it asks them for an id, which they can make with any letters or numbers (besides ones that look similar like 0 or O) which they can share with friends to get streetpasses with. you can enter someone's ID to send them a streetpass request, which they can deny, accept, and save for later. Saving for later would be keeping the person's ID for a future streetpass request, so you don't have to input it every time.

You could also just be assigned an ID, but where's the fun in that?

I just updated NetPass. It worked fine at first. Now it crashes my n3dsxl every time I check it.

update to v0.2.2

update to v0.2.2
I have this on 2 systems, both n3dsxl. The other one works fine with the update. I guess I'll wait till the 10 hours are up and try again. I'll let you know what it does.

It worked fine on both systems before I updated. Maybe if after the 10 hours it still doesn't work, I'll reinstall.

Hi. I downloaded your app via QR code yesterday and it worked fine. In fact, I even got 2 streetpass tags on MiiPlaza. However, when I tried it today it failed to connect to whatever location I select.

I get the following error:

ERROR: Failed to enter location 0: -409

I picked the Train Station this time but the error is the same for every location, the only thing that changes is the location (0, 1, 2)

I didn't even get an error code. When I used the app, it uploaded, downloaded and crashed about one second later. I could see the option to exit, but it crashed too quick for me to hit it.

Mind sharing the games you have set for Streetpass and current number of tags for each? Crash log looks similar to one I had, and might help to verify games/tag numbers (since different games have different limits on how many tags they can have).

Hi, I've just downloaded the latest version 0.2.2 and I'm getting the same error:
"ERROR: Failed to enter location 0: -409"
I can't connect to any of the 3 locations.

Okay, just had another crash using Netpass, and while it didn't happen on 12/12 (which I assume Streetpass Mii Plaza is for my Streetpass list), it very likely once again was caused by the app trying to add more tags than could be loaded in for the game the tags were downloading to. This has led me to formulating a suggestion to resolve this issue, one that might require workarounds and research to work (assuming it can work at all). It'd essentially go like this:
  • When uploading Streetpass data, check to see how many tags are already present for each game with Streetpass active.
  • Compare the tags already on the system to the max number of tags allowed for each game checked (this is the part that would require a good deal of research, as tag limits vary from game to game).
  • When tags are being processed, have the server check to make sure there's enough "space" to allow tags for a game, and skip any games that have already hit their cap. Alternatively, when downloading data for a game after uploading Streetpass data, prioritize the oldest tags on the server first, and stop the download and treat it as "completed" as soon as the tag limit is reached, ignoring any tags still remaining. The latter would be similar to how Streetpass normally works, but I would not be surprised it would be more difficult to implement.
I'm not entirely sure if any of this is possible, as I don't recall if any previous attempts to replicate Streetpass ran into and resolved similar issues. That being said, I can keep checking for these kinds of crashes on my end (and verify details if people are still having issues), and provide any information that may help to improve Netpass.

Edit: For those experiencing similar crashes (assuming you aren't deliberating attempting these crashes for testing purposes), the only thing I can suggest for now to avoid the issue is - if waiting at least 6 hours before checking tags - go into all games you have Streetpass tags for, and clear out those tags BEFORE you launch Netpass. This includes any Streetpass tags that you've acquired through official methods.

No problem. Just as a reminder, you can check all of the games you have Streetpass active for, as well as the number of tags in each game's inbox, by launching System Settings then selecting "Data Management" > "StreetPass Management". The number of tags currently present is shown by "Data Transmissions" when checking a title through StreetPass Management.

Having an issue on Ver 0.2.2 where it just doesn't update the street pass data. I get the green notification light on games, but going into them there is no registered tags
