Do you want to be able to share your BT speaker with your friends easily?
Do you hate connect your phone to your BT speaker as much as I do?
1. Going to settings
2. Turning your BT on
3. Search for devices
4. Select device
5. Connect to device
What if I told you you could do it in one step after this tutorial?
Or just wanna upgrade your (old) BT speaker; just because you can?? ;)
Step 1: Find Out Witch Type of NFC You Need.
I was looking for BT audio dongles for a friend of mine; a few had NFC; it made me think; how would such thing work?
Is it an active method? Or is it passive?
I think I can do it passively!
Let's look on ebay.
I found out there where multiple types of NFC; different wavelength, different storage-size and different uses.
which one do I need?
I've found out that I need, and it's the: NXP MIFARE - NTAG213
Multiple forums state hey're the best allround choice for most mobile devices.
Step 2: Purchasing.
I bought my NFC-tags on ebay.nl at 6 for €2,
but chances are, that you might find them somewhere China even cheaper ;')
Step 3: Writing the Tags.
Good options are: Trigger & NFC Tools.
My advice is; use em both, every time.
They both make your phone slightly react different; and the one time you like the one's app outcome more than the other.
(note: at the time that I actually made this i'ble this was the best way... since then the apps changed very much in a good way; so you might be good now with just one of them)
The programs are fairly easy to use :)
The're quite straight forward and no coding necessary; that has been done for you ^^
Just fiddle around a bit; and you'll get the hang off it easily :D
Step 4: Testing & Placing the Tag.
"Let's put it behind the battery-lid for testing! :D "
Abd then I was all like;
"Ahw menn; why ain't it working :( "
Thus I've found out the hard way; these tags don't work on/near metal :\
There's probably a good scientific reason for; but I can tell you without these specifics; it won't work.
Step 5: 1st Contact.
When I used Trigger it only prompted me once.
Every other time after this; it will simply connect when tapping your tag; without any other button-clicking required! :D
Step 6: Done!
Enjoy your deserved laziness ;D
