The sendFile() method of the MozNFCPeer interface sends a file — over a non-NFC data channel — to another device.
Note: sendFile() currently uses Bluetooth for data transport.
Syntax
var req = nfcPeer.sendFile(flieblob);
Example
var nfcdom = window.navigator.mozNfc;
nfcdom.onpeerready = function(event) {
var nfcPeer = nfcdom.getNFCPeer(event.detail);
var blob = ... // construct a 'blob' that is of type 'file'.
// This 'blob' will be passed onto / handover to Bluetooth interface for the actual file transfer. (Wifi handover is not yet supported)
var req = nfcPeer.sendFile(blob);
req.onsuccess = function(e) {
console.log("Successfully sent file");
};
req.onerror = function(e) {
console.log("Send file failed!");
};
};
Parameters
The Blob file reference to be transferred.
Returns
A DOMRequest object.
Errors
Error("Unable to create NFCPeer object, Reason: Bad SessionToken")
Specifications
The NFC implementation in Gecko follows the NFC Forum specifications.
