Hi Nemik, thanks for your helpful posts so far. I was able to activate the emulation mode on my Nexus S with the help of your patch. Now I am able to read and write the emulated tag with an external nfc reader. Is this want you meant with >> You can talk to it as if it were a MiFare card though if you don't do wired emulation mode. << Or is there a possibility to read and write the emulated tag with the Nexus S, perhabs via reflection? I need to read and write the emulated tag with an android application. Trying that so far just bring me to a Security Exception, WRITE_SECURE_SETTINGS permissions missing. Adding these permissions to the Android Manifest doesn't help. What do you mean with >> and key off of that UID from the emulated tag. <<
Thanks a lot. Martin On 3 Mai, 23:23, nemik <[email protected]> wrote: > 1. There are no examples, this is green territory. > > 2. Again, it's new and up to you.
