By default, NFC seems to be pretty low priority on the Puck.
If you install my NFC friendly firmware from RELEASE_2V06-NFC from my fork of Espruino you should see a lot more stability out of the behavior.
This version works to emulate the Lab401 Magic NTag 21x
It doesn't bother with the pretence of implementing write protection.
Most read/write behavior has been confirmed against actual NTag 215s and Magic NTag 21xs.
It currently uses a 584 byte tag. I suspect as I understand the NTag 21x spec better, it will grow to use the same 596 byte tag that Proxmark3 exports.
Implements all of the main commands in the spec. READ_CNT is likely not correct, however.
In addition, there are the read/write pages from the Magic NTag 21x interface:
| Type | Page | Purpose |
|---|---|---|
| Command | 0x88 | resets the tag, reads in an updated UID |
| Address | 0xF0 | Password (4 bytes) |
| Address | 0xF1 | PACK (2 bytes) |
| Address | 0xF2-0xF9 | Signature (32 bytes) |
| Address | 0xFA-0xFB | Version (8 bytes) |
| Address | 0xFC | Mode on Magic NTag 21x, not implemented here, since we currently only handle NTag 215 emulation. |
When the data on the tag becomes "Dirty", the Blue LED will light up.
The only thing this will impact is that the UID you can read directly is NOT the UID that is advertised, if you have changed the UID during writes. All other write actions are incorporated immediately, as the internal _page Uint8Arrays all reference the _data.buffer as a source.
To make the tag pick up it's new UID, simply give it a click or send command 0x88.
Max time between clicks for them to increment: 1 second
| Clicks | Action |
|---|---|
| 1 | Restarts the tag to pick up new UIDs |
| 3 | Reboots the Puck. If you haven't ran save() you will lose your current state. |
- It works with the proxmark3
mfu_magicscript for setting properties. - It works for being read as an amiibo with a properly written tag.
- It works as being written to as an amiibo with a properly written tag.
Resets the tag back to a 'Know Good' and clean state.
Creates a new Uint8Array, runs wipe, and returns it.
Outputs a formatted dump of the tag to the console. Dump is in JS format designed to be efficiently loaded back in to the Puck, and also easily diffable against other dumps to view changes.
You can see examples of this in the ndef folder.
main file goes in: src/<target>/app.js
Additional files go in src/<target>/<subdir>/<file.js>
Use ES6 syntax to include local files:
import Foo from './libs/foo.js';
Use OldSchool syntax to include Puck modules:
const Storage = require('Storage');
gulp --target <target> rollup
puts a file in dist/<target>/app.js
gulp --target <target> upload
uploads dist/<target>/app.js to your puck
gulp --target <target>
builds dist/<target>/app.js and uploads it.
