title: Emulate reading a tag on an Android phone
body: <p>Is it possible to inject previously recorded NFC sequences into NFC stack in Android, so that the applications on the phone would think that tags are being read?</p>
  
  <p><strong>Edit:</strong></p>
  
  <p>Sorry for bad description</p>
  
  <p>I don't have any code I'm just investigating the possibilities here.
  In short what I want to achieve is this:
  There is a FGM Sensor Called FreeStyle Libre, which in (v1) can only be read via NFC. I want to create a "dongle" that will read the sensor and forward the raw data to the phone via bluetooth. Some things like that exist but I want to use the original application for it (raw data is processed via specialized algorithm), so the idea for injecting somehow the data from a BLE receiver app into Android stack where the application is running, low level API might not be necessary, perhaps I've overstated the NFC stack. I've read somewhere that I could inject this on with a higher API (NDEF injection something like that).</p>
