Remarks
Send raw ISO-DEP data to the tag and receive the response.
Applications must only send the INF payload, and not the start of frame and end of frame indicators. Applications do not need to fragment the payload, it will be automatically fragmented and defragmented by #transceive if it exceeds FSD/FSC limits.
Use #getMaxTransceiveLength to retrieve the maximum number of bytes that can be sent with #transceive.
This is an I/O operation and will block until complete. It must not be called from the main application thread. A blocked call will be canceled with IOException if #close is called from another thread.
<p class="note">Requires the android.Manifest.permission#NFC permission.
