[Testing] NFC for Halium 9 ports

mateo_salta

we could also make a system settings page,
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,

mateo_salta

oh, I see the settings page in github, cool. is there going to be a indicator?

PhoenixLandPirat

@mateo_salta maybe it should just be added to the bluetooth indicator instead of making a seperate one for it

fredldotme

Maybe we can consolidate WIFI, Bluetooth and NFC into one indicator in the future, but that's out-of-scope for the initial release.

mateo_salta

@fredldotme yes, i think the plan is location, bluetooth, ect. as the other networking options are together, wifi, ethernet, cellular

mateo_salta

I think we would also want to build in automatic uri/url handling -
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

fredldotme

@mateo_salta I've already taken a look into QtNfc not allowing writes, I know where to enable 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.

mateo_salta

@fredldotme cool, will be great to have the app usability at first, thank you for all the wor.

mateo_salta

@mateo_salta i could probally write a basic app that just passes on the url to urldispatcher as a stopgap, i think that will be my next thing to try

fredldotme

@mateo_salta Could you possibly release a version of your demo QtNfc writer app with the nfc policy group enabled? I would like to test it in a confined environment. Or even better, could you release the source code for it?

domubpkm

NFC should be in next dev :
https://github.com/ubports/ubuntu-touch/issues/1697
But in concrete terms, what will this technology implemented on UT smartphones allow us to do in daily use?

fredldotme

@domubpkm depends on what app developers can envision and implement with it. It could be used for home automation for example, triggering events via NFC tags.

kugiigi

I almost never used NFC in my life. Maybe once or twice I used it to automatically pair bluetooth devices
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

mateo_salta

@fredldotme oh yeah, the source is in the example folders of qt-master, they have a handfull of demos, I will try the apparmor, didn't know that was going yet

mateo_salta

@kugiigi I'm looking foward to trying this example, ( https://github.com/qt/qtconnectivity/blob/8618e25e01ca9c6c6b2221041f625ac69f6757b8/examples/nfc/corkboard/corkboards.qml) and sticking some of the stickers on my refrigerator as notes

flohack

Is there already a test app? I have at least one device here where I would love to test it...

fredldotme

@flohack https://github.com/fredldotme/ut-nfc-ndef-demo and https://github.com/fredldotme/ut-nfcd-p2p-demo respectively

Luksus

@fredldotme I tried to build the p2p-demo with clickable, but get the error, that "nfc" is an unsupported policy-group... do I have to use some modified docker image for building this?

flohack

@fredldotme I meant a click to be installed for the lazy of us...

fredldotme

NFC support has been merged into Clickable just recently. Using Clickable from git will work.
