I am trying to send following NDEF message from a windows application to Android phone through ACR122U-A2NR.

43200001000000010100000027D101235402656E53746172742C4775696C6C61756D6520424552544541552C313233342C456E64

On the windows end I’m sending NDEF message using following sequence of commands.
(For this I use winscard.dll).

  1. “FF0000002DD48C0100000000004001FE0FBBBAA6C9890000000000000000FFFF01FE0FBBBAA
    6C98900000646666D01011000”
  2. “FF00000002D486”
  3. “FF00000015D48E0520060F636F6D2E616E64726F69642E6E7070”
  4. “FF00000036D48E43200001000000010100000027D101235402656E53746172742C4775696C6C6
    1756D6520424552544541552C313233342C456E64”

Application on Nexus S android 2.3.4 is working fine. While same is not working on Samsung SII android 2.3.4.

In case of Nexus S command #4 returns “D58F00” (Success)
In case of SII above command returns “D58F25”. Where “0x25” is error code for :
DEP protocol:Invalid device state the system is in state which does not allow this operation

    Are you trying this with ACS SDK or an alternative?
    Have you checked nfctools library? http://www.grundid.de/nfc. I think they have better support for P2P communications since it fully implement the android protocols specification (although still have some bugs).
