What is syntax for wifi to write to an NFC tag with which WIFI of android phone should be activated? I have already used "wifi://[ssid]/[wpa]/[pwd]", but it is not working. Can anyone help?

I’m creating a mobile application that fetched data based on ID which generated on PC. I want to pass this ID as a text string from my NFC device which supports read and write to an iPhone device when the user touch on the NFC device.
Is this possible?
I’m using Acr 122u as an NFC device.
The short answer is it is not possible with iOS
There are 3 basic modes of operation of NFC devices - Reader/Writer, Peer to Peer and Host Card emulation (HCE).
iOS only supports Reader/Writer for developers (though HCE is used by Apple for their wallet stuff)
Android supports Reader/Writer, Host Card Emulation and Peer to Peer (Up to Android 10 when it was removed)
Most USB readers I've seen only support Reader/Writer.
To use NFC without a real NFC Card
Both devices must support Peer to Peer
Or
One must support Reader/Writer and the other must support Host Card Emulation.
From iOS 13 SDK apple add NFC for read tag and you can use NDEF type message.

I would like to use a Apple mobile device (iPhone, iPod touch) to connect to a Windows CE device via bluetooth, but it failed. Iphone returns an error message that the device is not supported.
I understand about the MFI process but it's too difficult to get approval from the Apple MFi Team for a Windows CE device so I don't even bother to try.
Another way is change the bluetooth profile in the WinCE so make it as a headset or bluetooth keyboard so hopefully Apple can discover it as another device and accept the connection. I have the CERegEditor to modify the registry and also a COD generator from this link (http://bluetooth-pentest.narod.ru/software/bluetooth_class_of_device-service_generator.html). I modify the bluetooth profile successfully on the device and verified by Android. However, I'm still not able to use a iPhone to connect to it.
I tried to make it as a wireless headset or hands-free but it's not discoverable by the iPhone, or it just directly refused to connect.
If I made it as a keyboard, it's discoverable by the iPhone, but it doesn't connect after I send a pair request and type in the correct 4-digit pin. iPhone returns the "out of range" error even it's just next to it.
I hope I can get some help here. I appreciate if anyone can share similar experience before or provide me an appropriate COD code which works for you, or any other methods that can let me to make a connection.
Thanks for your attention.
Does anyone have example with iOS/Objective C, on how to send midi "note on/note off" signal (with different velocity) over wifi so that iPad would display in "Mac OS X->Audio Midi Setup->Network. then I click connect device" and by simple touching on the button on iPad code will send midi command. I believe I need to use some protocol,but I'm newbie on this, please help me.
Thanks.
You have to use the coremidi framework (provided by the IOS). See here for a introduction: http://www.synthtopia.com/content/2011/06/02/coremidi-brain-dump/
If you are still looking I wrote sample code that is on GITHUB that wirelessly sends/receives MIDI notes ON/OFF messages from iPhone/iPad to Windows PC, Apple Mac or any other device listening. Full instruction on GITHUB.

I have a printer which supports the printing over the bluetooth network .
I searched for printing from iOS and went through the Apple documentation on UIPrintInteractionController class . But no where it has been specified whether it can use bluetooth to make the connection to the printer or not ? I know it works on the Wifi .
Can any one suggest any tutorial or any link on printing from iPad using bluetooth ( if at all possible )
Please help me with this !!!!
The AirPrint protocol uses a WiFi network to detect compatible devices. I don't think it's possible to print via Bluetooth in iOS as of yet.
I have Installed Android Nexus S emulator on my linux machine, as well as my Windows machine.
While opening the NFC tag on emulator I am receiving the error: 'NFC is not supported'. As I am developing an application on NFC, I need to have NFC support on my emulator. What else do I need to do to make this work?
This will be very helpful if anyone can share ideas on this problem
the best way to deal with NFC is use the real phone - this is same with all HW features on mobile phones (camera, GPS, etc)...
