NFC

[Updated] NFC Toolkit uri schemes

app2app_nfctoolkit

If you are following me, you might have noticed that uri schemes actually are playing a big role in my Windows Phone apps. (read more)

NFC Toolkit, one of my main projects, offers now also the possibility to interact with your apps.

One of the unique features of NFC Toolkit is profiles. Profiles are designed to open up to 5 settings pages in a row (as directly setting them is not possible because of OS restrictions). At the end of a profile, an extra from within the app or another app can be launched.

In Phase I, NFC Toolkit enables other developers to add their custom uri association/scheme to the list of launchable apps in profiles.

Here is how the uri needs to be formatted to work:

"nfctoolkit:addmyapp?appname=<yourappnamehere>&urischeme=<yoururischemehere>"

I will add more uri associations with the next updates and update this post with them.

[Update 2]

Starting with version 0.9.8.1 of NFC Toolkit, I added new uri schemes to enable you to write data on NFC tags. Here is the list of possible writing records:

  • website record:
"nfctoolkit:writetag?type=smartposter&url=<url>&title=<title of the website>&languagecode=<two letter lang code (standard: en)>"
  •   text record:
"nfctoolkit:writetag?type=text&content=<your text here>&languagecode=<two letter lang code (standard: en)>"
  • send mail record:
"nfctoolkit:writetag?type=mail&mailaddress=<mailaddress>&mailsubject=<mailsubject>&mailbody=<mailbody>"
  •  settings page:
//supported pages: flight mode, cellular, WiFi, Bluetooth, location, lock screen
"nfctoolkit:writetag?type=settings&page=<settings page name as listed above>"
  •  launch system app:
//supported pages: 
//"Alarm", "background tasks", "brightness settings", "Bing Vision", "Calculator", "Calendar", "call history", 
//"Camera", "Data Sense", "date + time settings", "ease of access", "find my phone", "Games", "Help+Tips", 
//"Internet Explorer", "internet sharing", "keyboard settings", "kid's corner settings", "language + region settings", 
//"Maps",  "Messaging", "Music+Videos", "Office", "OneNote", "People", "Phone", "phone information", "Photos", 
//"Rooms", "SIM Applications", "Start", "Store", "theme settings", "Wallet"
"nfctoolkit:writetag?type=sysapp&name=<system app name as listed above>"
  •  launch any app by name or publisher name:
//launches the store page search in NFC Toolkit and searches for the app/publisher
"nfctoolkit:writetag?type=launchapp&appname=<app name or publisher name>"

On top of that, I added an uri scheme that allows a plain launch of NFC Toolkit:

"nfctoolkit:home"

I updated my custom uri scheme test app as well for you. Download it here: CustomUriSchemeTestApp

Happy coding everyone!

How to save a List or a Collection on a NFC tag

 

WP8_NFC_PostLogo

As I am currently working again on my NFC app, I needed to save an ObservableCollection to a tag. My first attempts resulted in a heavily overlong string that I wasn’t able to save.

Anyways, after a short convo on Twitter, I went for the right way – serialize to JSON.

The first thing you’ll need for that is the JSON.NET library, which you can get here or via the NuGet package manager in Visual Studio.

After that, you will be able to save your List or ObservableCollection in a few easy steps.

One thing I need to recommend is to make the names in your class/viewmodel as short as possible. Here is my example:

public class ListItems
    {
        //ListItems
        public string i { get; set; }
        //isChecked
        public bool iC { get; set; }
    }

You will need every space you can get on your tag, so you really should go for a similar way like I did above.

After you are done with that, you only need one line of code to convert your List/Collection for writing on your tag:

var ListToSave = JsonConvert.SerializeObject(ItemsList);

Now you will be able to save it as a Text record or  whatever record type you need to save it to.

Deserializing the JSON string works also with only one line of code:

ItemsList = JsonConvert.DeserializeObject<ObservableCollection<ListItems>>(StringFromYourTag);

Then you set the ItemsSource of your ListBox to that (or whatever else the List/Collection is for).

I my case, I was able to save a Collection of 25 items to my tag (writable size 716 bytes) with having still about 200 bytes left in this way.

As always, I hope this will be helpful for some of you.

Happy coding!

Announcement: beta test for NFC Toolkit

 wp_ss_20130201_0002

NFC Toolkit, my latest app project, is ready for a first beta look.

If you want to take part in this beta, please consider following points before applying:

  • You need a WP8 device with NFC
  • You will need NFC tags for now, as communication between devices is still in development
  • You are willing to give serious feedback to improve the app

This will be a long time beta, means that even if the app goes live for all customers, I will continue developing with this beta before launching new versions. If you join the beta, you can use and test all new features before all others.

NFC Toolkit aims at normal users, that don’t need all to technical information but want to use NFC.

The beta has following features at the moment:

  • basic tag reading
  • tag writing of most commonly used tag scenarios
  • profiles! This is one of the main features of NFC Toolkit. It is all about settings based on a NFC tag.
  • more unique features to come!

Application ID’s of built in Windows Phone 8 apps

 

As you may have noticed, I am currently working on an NFC app. Development goes pretty well at the moment, thanks to the absolutely awesome and easy to use NDEF library by Andreas Jakl.

If you want to open apps from your app or from an NFC tag, you will need to use the AppId of the desired app. If you have an installed app from the Windows Phone Store, this is pretty easy. You can go to the application list on your phone, long tap and hit “send”. If you now choose mail or SMS, you can obtain the AppId very easy, as it is the last part behind “appId=” on the web address.

With the built in apps, it is a bit more difficult. Luckily, the app NFC interactor for Windows Phone 8, which is aimed at developers, has a solution. The app is written also by Andreas Jakl, who provides a huge tool with this app to support you on developing your own app and it is worth every cent.

I made it through all records for built in apps and extracted the following list, which might come handy for some of you:

  • Alarms AppId 5B04B775-356B-4AA0-AAF8-6491FFEA560A

  • Wallet AppId 5B04B775-356B-4AA0-AAF8-6491FFEA5683

All credits for this App IDs goes to Andreas Jakl, I only put them together as a list to find them more easily.

Tap+Send: The Love Story of 2 NFC Devices

NFC1

Innovation in technology is hit and miss for a number of reasons. To prognosticate what advances in technology will be accepted by the general public is by no means, an exact science. There’s a constant barrage of new expensive toys with exclusive features that are “sure” to turn the world upside down, only to hit the market and fade into oblivion as a “niche market” concept. There are more than a handful of these types of advancements in the devices we all use on a day-to-day basis now, regardless of preferred OS. Yet for all intent and purpose, most don’t get utilized because of a lack of end users with similar features. NFC is one of those exclusive features and having 2 devices with it, I’ll explain why I see this being a feature that is here to stay.

nokia-speakers

I won’t spend much time explaining NFC as most of you know about it. Quickly, NFC(near field communication) is a set of standards for devices to establish radio communication with each other by touching them together or bringing them into close proximity. Up to this point, most of the NFC ado has been made about NFC tags and the Qi wireless charging capabilities with our Windows Phone 8’s: Charging plates, charging stands, phone covers with Qi, the JBL PowerUp speaker that can charge your device while playing. Being such a new innovation in smartphones, there are limited accessories to aid in this new technology, even HTC used JBL’s speaker for Nokia to advertise its most recent Android device. In addition to the lack of accessories currently available for NFC enabled devices, there are a lack of end users who actually own a NFC enabled device. NFC is about sharing and if you have no one to share with, it becomes one of those “niche market” features fading into the past, full potential never being realized.

tap-send-wp8

My wife and I both have Nokia Lumia 920’s which has led to a unique experience among smartphone users, being able to utilize many aspects of the NFC’s features and that is what I’ll focus on now. One of the drawbacks to WP7 was the inability to share via Bluetooth. This was remedied in Windows Phone 8 allowing for the next evolutionary stage is sharing photos, videos, songs, documents, contacts, or websites…via NFC. No more waiting while you tried to get your Bluetooth to find the other incompatible device right next to you, no more waiting for the other person to email you with that important file or pic even though they’re standing next to you, no more waiting for file to download when opening your email, no…things have changed. Tap your phone and give or get that info now in a fun and engaging manner! I am beginning to see the Tap and Share feature as perhaps the most innovative feature with the largest amount of potential to the end-user. Of course like most new technologies this is assuming it can make it onto enough devices and into enough hands, driving the hardware cost down and finding its way onto lower cost devices for the masses to use. Without “the masses”, NFC, aside from wireless charging, losses its luster. In some sense, I’m actually rooting for HTC and Samsung to have some success with their Android devices utilizing NFC, the better they do, the better results all OS’s with this feature will do. Again, NFC’s success really does rely upon the masses.

Share1

My wife and I use the Tap+Send feature frequently. We’re constantly sharing pictures and with Tap+Send, it’s always much faster and a sure bet the recipient gets the file! I’ve found that we’re both more likely to share pics when it’s as simple as Tap+Send. Send 1 or send multiple, it doesn’t matter. Honestly, I’m finding myself impatient now when I know someone is sending me a file and I have to wait for it to arrive in my inbox and still have to download it! Another added benefit to sharing your pics or videos via NFC is the data aspect. I avoid having to use up my allotted data both with my carrier and at home on WiFi, for those of you with shared family plans or have data limits because of satellite internet, you understand.

App

A close 2nd in utilization when it comes to Tap+Send: App Sharing, we do this at least once a day! As many of you know sharing apps via your WP8 was made easier by Microsoft when they gave us the ability to share it directly from the app side of your device. By pressing and holding an app, “Share” is now listed as on option and even better…you can do it via Tap+Send! Lightning fast access to the app’s direct link in the Windows Phone Store! Again, no waiting for it to show up in your inbox, it’s just there! I actually transferred all my apps this way when switching over from my old 920 to my new 920 to see how arduous it was. I’ve used App Reinstaller and it can take quite a long time to auto-populate your entire app history. I was blown away at how fast I was able to get my new 920 up and running with all my old apps!

sharing

We also share music via Tap+Send. I’m going to start by saying that neither of us has a music pass of any sort. When we see something we like we purchase it, so I’m not sure how sharing music on a pass will work. My experience with music and Tap+Share has been sending and receiving music from my computer or music purchased from Zune and Xbox Music, all which has transferred and played without a hitch! It’s a relatively quick process, taking about 30 seconds from share to play!

Contacts1

My wife and I have busy schedules between our marriage, kids, friends, activities, and work. We have many people who are friends in common and some aren’t for one reason or another, thus our people hubs are similar but not an exact match. There are many apps that help share contacts and WP does a pretty good job at giving you ways to share contacts as well, however none come close to the efficiency and speed with which you can do it when shared using Tap+Share! 2 taps and a phone “high-five” and the info is waiting to be saved.

Ready-for-enterprise

The last way I’ll look at is actually tied into the “Gold Mine” Microsoft sees in enterprise, sharing your documents via Tap+Send. The ways I’ve talked about using Tap+Send have been for the average user, but we all know that Microsoft is targeting businesses globally with WP8. The ability to share documents as simply as touching phones can be a game changer. Running late and can’t wait for that file to get to your inbox…need it now…phone “high five” and off you go! Not a gimmick, time is money and that makes dollars and sense!

I hope in time that we’ll see more and more devices showing up on the market NFC enabled at every level of phone: high, mid, and low range. This will take time but it’s time well worth it. When I stop and think back 2 years ago, I think about my Windows Mobile HTC Touch Pro 2, it could share via Bluetooth but it was a disaster of a process to get it to pair or be paired with not to mention the inability to retrieve most of the files types being sent! Our beloved Windows Phone has come a million miles from its predecessor, not without bumps in the road. Without those bumps though, many would forget all the amazing feats accomplished and adversity Microsoft/Windows Phone has managed to overcome!
