Writing NDEFMessages

Hello,

I'm playing with an example that tries to write a new NDEFMessage to a card. Everything works fine until the writeNDEF method on the NDEFTagConnection class is used. No reaction at all, the code snippet is as follows:

try {
        conn.writeNDEF(newMessage);
        form.append("new message written: "+msg+"\n");
} catch (ContactlessException e) {
        log("ContactlessException: "+e.getMessage());
        form.append("ContactlessException: "+e.getMessage());
} catch (IOException e) {
        log("IOException: "+e.getMessage());
        form.append("IOException: "+e.getMessage());
} catch (SecurityException  e) {
        log("SecurityException : "+e.getMessage());
        form.append("SecurityException : "+e.getMessage());
} catch (Exception  e) {
        log("Exception : "+e.getMessage());
        form.append("Exception : "+e.getMessage());
}

I got no exception neither any message. I'm doing the same test writing the same NDEFMessage that I read and got the same result.

Does anyone succed in writing NDEFMessages?

Thanks
