New version and PowerTag.

[KikiNeosquall]

Hello.
The new version don't write on my PowerTag, but the old (2.7.0) yes.
Any ideas ?
PowerTag support is enabled.
Thank you ! 😃

[HiddenRambler]

I will attempt to test this in the weekend. I need to find my old powertags.

[AbandonedCart]

I've tried not to mess with that code much because I don't have the hardware, but it's quite possible some other change broke it.

Another way to get an idea of what's going on would be to use the logcat option in the menu. If it's an issue with the app, it should print there.

[AbandonedCart]

I think #258 may have uncovered the issue. It should be solved.

sry the problem is the same
i have installed the new version
if i want to write a amiibo to the power tag:
PowerTag key not loaded.

just like the version before. the option for powertag is of course on.

@XiNaru You're using the one marked pre-release right? https://github.com/HiddenRamblings/TagMo/releases/tag/experimental

You shouldn't be able to get to that error without first getting a toast message about the keys failing.

i try it again

[XiNaru]

OKay NOW it comes a new error message:
No avaible key for UID

[XiNaru]

Thank you very much :)
I look forward to a version that works in the end :)

[AbandonedCart]

Looks like the other issue may have been a somewhat silent limitation on resource size when not using assets.

[XiNaru]

which version must i download=? the experimental AND the normal release are bothe 10 hours ago :)

Edit: i have see the time witrh mouse hover.
the latest is experimental, the problem is the same :)

[AbandonedCart]

That was all the obvious possibilities. A logcat may reveal any hidden causes, though. I recommend trying after a fresh reboot of the phone and then clicking the last item in the three dot dropdown menu.

[XiNaru]

so i did.
cell phone restarted.
program started.
first scanned an active amiibo to see if that works. the part went.
then I tried to write an amiibo: the UID error message.
Logcat: I can't find the one that was created. where on the cell phone is the o.o.

[AbandonedCart]

Should have written to /sdcard/Android/data/com.hiddenramblings.tagmo/files/

[XiNaru]

no there is no folder with the name. I'm looking for the directory but can't find anything.

even saved amiibos are saved in the root directory of the sd card.

[AbandonedCart]

What is the phone and Android version this is running on?

[XiNaru]

What is the phone and Android version this is running on?

        if (keys == null)
            throw new Exception(TagMo.getStringRes(R.string.powertag_key_error));

        byte[] uidc = new byte[7];

        uidc[0] = (byte) (uid[0] & 0xFE);
        uidc[1] = (byte) (uid[1] & 0xFE);
        uidc[2] = (byte) (uid[2] & 0xFE);
        uidc[3] = (byte) (uid[3] & 0xFE);
        uidc[4] = (byte) (uid[4] & 0xFE);
        uidc[5] = (byte) (uid[5] & 0xFE);
        uidc[6] = (byte) (uid[6] & 0xFE);

        HashMap<String, byte[]> keymap = keys.get(Util.bytesToHex(uidc));
        if (keymap == null)
            throw new Exception(TagMo.getStringRes(R.string.uid_key_missing)); <- This is the error

[XiNaru]

i don't have an SD card.

I am in the picture in the ROOT of the mobile phone. and after what you say you would have to create the sd folder in the root of the cell phone, which does not happen.

[AbandonedCart]

Android/data/com.hiddenramblings.tagmo/files/tagmo_logcat.txt

[XiNaru]

the folder /adnroid/data is empty at me.
and i have show the hidden files

[AbandonedCart]

The folder isn't actually empty, but that browser blocks viewing it. Some did that. Looks like I will have to add a way to get to it into TagMo

[XiNaru]

but why? i have activate to show all hidden files.

[AbandonedCart]

Some file browsers treat it as app-specific storage and don't request the permission to view it.

[XiNaru]

understand. i can't find a way to get around that on the internet either. despite developer options.

[AbandonedCart]

I added a view option to the popup that should allow you to open it in anything that allows viewing files. That should at least let you read, copy, or save it somewhere else.

[XiNaru]

but now i uploaded a txt file

Got it. Thanks.

I went back and read through past issues and the documentation. I never asked if you have been previously using the tag with the official app. If so, a reset is required. Check the link above for details.

Okay NOW it works lol :)
but if i read..is Tagmo for using with powertag unsecure?

[AbandonedCart]

Not insecure, just not officially supported. We have to use a slightly modified method because the official one has not been made public.

[XiNaru]

well i asked because you were unsure because you wrote that there are rumors that the powertag could lose its data after a certain type of write process?

[AbandonedCart]

It's after a certain number of writes. That applies to TagMo, PowerSaves, and any other app or read / write hardware. They are known to wear out over time.

[XiNaru]

Es ist nach einer bestimmten Anzahl von Schreibvorgängen. Das gilt für TagMo, PowerSaves und jede andere App oder Lese-/Schreibhardware. Sie verschleißen bekanntlich mit der Zeit.

oh so it has nothing to do with tagmo, but can it also happen with my official powersaves software?

[AbandonedCart]

Yes. That is how they make them so affordable.

[XiNaru]

okay i understand
now it works, thanks.

[AbandonedCart]

@KikiNeosquall Is your issue resolved, as well?

Closing this for now, but it will be opened again if it is not.

[KikiNeosquall]

Sorry, I just checked now, and it say "No available key for UID"

[AbandonedCart]

Did you perform the setup?

[KikiNeosquall]

Oh it works !
Thank you very much ! 😃
