Update to Prusa app for NFC

A useful update it seems, so I tried to "create a new NFC tag" and you can see part of the result in the photo.   There's an impressive inventory of manufacturers and types.  It's also easy to enter the weights, just touch on the edit symbol.  BUT the TAGs ?? !!!  

In this case (Centaur PP white) the given tags are (a) wrong and (b) uneditable.

I'm happy to be corrected, but that's what it seems to me.

RE: Update to Prusa app for NFC

Not exactly sure what you mean by "tags are uneditable." First, which tags are you trying to write to? Which application are you using? The OpenPrintTag website? What tags are you writing to? Are they Prusa's OpenPrintTags or something else? If the later are they SLIX2 320 byte compatible tags?

If you want to use a full featured app there are a few options. On the iPhone (and Android I believe) there is an app called NFC.Cool that allows you to edit tags. Also, I've developed an application: Filament DB that does the same however at the moment it only runs on a desktop but is currently being ported over to iOS and Android.

  🙄 I did write the title "update to Prusa app for NFC".   And I attached a photo.  What more could I say ?  Maybe I should have said the "Prusa Android app".   Yes I'm aware of those other options but am only looking at the Prusa app at the mo.   I'm not necessarily editing tags either, just following the developments and I can see that the Prusa app should be able to edit them.  But it seems (at least in the regard I described) to have a couple of deficiencies which I hope Prusa will recognise and fix.   I have a bunch of blanks anyway that I could experiment with.

The current Prusa app only allows you to write to a tag using predefined templates. You can edit the spool weights but not other fields. If you want to create a custom tag for your filaments, for now you need to use a different app such as NFC.Cool. I'm not sure if the Android version supports OpenPrintTag. For sure it is supported on iOS.

Well Prusa need to know (do they read this?) that at least in my experience, some of the app's pre-defined templates are wrong.  I know it's early days and the app (the NFC hardware) is not really in use yet ...

It's just for having a play and not doing anything serious (yet).
