<![CDATA[[Testing] NFC for Halium 9 ports]]>EDIT April 3rd 2021: NFC support is now in the devel channel and will be released with OTA-17
Please use this thread as a place to exchange ideas regarding our NFC implementation.

Original post:

Hey! I have something new to play around with for people on Halium 9 builds of Ubuntu Touch: you can now test your device for NFC functionality!
The only prerequisite is that your device needs to be on the devel-based rootfs, not the edge one.

To install:

sudo ubports-qa install xenial_-_android9_-_nfcd
sudo mount -o remount,rw /
sudo apt install nfcd nfcd-tools nfcd-binder-plugin nfcd-repowerd-plugin

To get console output from nfcd:

sudo stop nfcd
sudo /usr/sbin/nfcd -p /usr/lib/nfcd/plugins -v

App developers can try the QtNFC integration module to develop apps based on this technology. This requires the following change to be made to the rootfs before it can be used by (currently only unconfined) apps:

sudo mount -o remount,rw /
sudo apt install qml-module-qtnfc

The API documentation is located here: https://doc-snapshots.qt.io/qt5-5.9/qtnfc-qmlmodule.html

Please use this thread to share your experience with NFC enablement and even ask for help.

But that's why I'm really looking forward having it on UT because I'm pretty sure I will use it. I've used a lot things just because they are available on UT 😁

It could be used for home automation for example, triggering events via NFC tags.

But in concrete terms, what will this technology implemented on UT smartphones allow us to do in daily use?

I would like to test it in a confined environment. Or even better, could you release the source code for it?

Might take some time though.

For the URL handling: Yes, this has also been requested by Nymea devs, but at the current pace it might not make the cut for OTA-17.

Many tags are written to launch a website/url, and we would want these to be sent to the url dispatcher automatically, would be simple to just call open url externally, url dispatcher takes care of the rest.

I have received new tags, and once written on another device the app i compiled reads then perfectly, we may need to recompile something to enable writing, as the code comments that it was disabled.

The tags I got are ntag 213 ( a watch style tag, and a ring style tag) I plan on writting a custom url (i think "clock://" to open the clock on the "watch band", then maybe we can see what it would take to make a password ring 🙂

not sure what all will go in besides on/off right now
ideas:
-allow tags to wake device - or not, turn off service on sleep?
-configure tag for long random string, for secondary login like fingerprint (then pin + tag unlock setting) (there are nfc rings perfect for this) or put on your favourite speaker and have it unlock and launch music player automatically?

  • maybe display plain text tag as notification?
  • emulate tag, for phone to phone, touching messages/browser url share,

If someone can confirm the program works, I can try and compile the other qt examples to use

that it was detecting like it was, I think it is working as it should then 🙂 Looks like I need to find some different tags 🙂 no worries, these were old 1kb.

researching more, perhaps these: https://www.adafruit.com/product/4032 , the website even sites problems with mifare: "Unlike "Classic 1K" cards (a.k.a MiFare S50s), these tags are more secure and work with almost any phone with RFID support since they avoid the patent issues with Mifare, which requires an NXP chipset or license fee."

I made a experimental test click https://drive.google.com/file/d/1xowIZQAyynsnLAjtzGX7Wxsa1iNkNeTb/view?usp=sharing

It seems that it does not read my tag, or tries to read it in terminal. I will have to try more tags. This one is a small nxp mifare classic 1k "ISO 14443-3a" I have written a url on it with another phone.

non-verbose, shows terminal "target is gone" - perhaps is a unsupported tag? verbose:
http://paste.ubuntu.com/p/qr9tKvwDd8/

Writing fails with this error(ignore the top, i misspelled the binary at first ;P): http://paste.ubuntu.com/p/QW47SKyJS9/

"QNearFieldTarget::WriteNdefMessages() disabled. See QTBUG-43802"

Very interesting testing, i will need to try more tags.
