From 57560c3290c6c0f92f87f31e2378b2a14e2d6e63 Mon Sep 17 00:00:00 2001 From: Romuald Conty Date: Mon, 18 Oct 2010 15:17:31 +0000 Subject: [PATCH] Document the ACR122 problem. Update Issue 117 Status: WontFix ACR122 device support is limited. We can not provide a rock-solid support of emulation on these devices this way (talking directly to PN532). --- examples/nfc-emulate-forum-tag4.1 | 8 +++++++- examples/nfc-emulate-tag.1 | 6 ++++++ examples/nfc-emulate-uid.1 | 6 ++++++ 3 files changed, 19 insertions(+), 1 deletion(-) diff --git a/examples/nfc-emulate-forum-tag4.1 b/examples/nfc-emulate-forum-tag4.1 index 9958d0c..9d02dac 100644 --- a/examples/nfc-emulate-forum-tag4.1 +++ b/examples/nfc-emulate-forum-tag4.1 @@ -17,6 +17,12 @@ At the moment, only the Nokia 6212 Classic can be used with this example because it's based on a pre-established communication plan and the tool sends blindly the expected replies to the initiator without having interpreted the queries. +.SH IMPORTANT +ACR122 devices (like touchatag, etc.) can be used by this example, but if +something goes wrong, you will have to unplug/replug your device. +This is not a +.B libnfc's +bug, this problem is due to ACR122's internal MCU in front of NFC chip (PN532). .SH BUGS Please report any bugs on the .B libnfc @@ -28,7 +34,7 @@ and .B libnfc-examples are covered by the GNU Lesser General Public License (LGPL), version 3. .SH AUTHORS -Roel Verduly +Roel Verdult .PP This manual page was written by Romuald Conty .
