Hi,
I have successfully ported hcidump into android so that we are able to
monitor data send by bluetooth interface.I would love to write a blog post
on it explaining how to compile it at umit blog.
I have compiled it on Ubuntu 11.04 64 bit for Android 1.6 . I'll provide
the instruction for 32 bit in blog post.
Here are the basic instructions:
APP_ROOT represent application root folder.
We need to download following things:
1- Bluez code:
from: https://android.googlesource.com/platform/external/bluez.git
into: folder named "bluez" at APP_ROOT/jni/
2- Frash code:
from:
https://github.com/comex/frash/<https://github.com/comex/frash/tree/master/utils/cutils>
into: folder named "frash" at APP_ROOT/jni/bluez/libs/
3- Bluez-repositories:
from: git://git.kernel.org/pub/scm/bluetooth/bluez.git
into: folder named "bluez-repos" at APP_ROOT/jni/
edit Android.mk at APP_ROOT/jni/bluez/libs/ to :
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES:= \
src/bluetooth.c \
src/sdp.c \
src/hci.c
LOCAL_C_INCLUDES+= \
$(LOCAL_PATH)/include \
$(LOCAL_PATH)/frash/utils
LOCAL_MODULE:=libbluetooth
LOCAL_CFLAGS+=-O3
include $(BUILD_SHARED_LIBRARY)
copy all files from APP_ROOT/jni/bluez/hcidump/ into APP_ROOT/jni/
then edit APP_ROOT/jni/Android.mk to:
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_C_INCLUDES:= \
$(call include-path-for,bluez-libs) \
$(LOCAL_PATH)/bluez-repos/lib
LOCAL_CFLAGS:= \
-DVERSION=\"1.41\" \
-lbluetooth
LOCAL_MODULE_TAGS := debug
LOCAL_MODULE:=hcidump
LOCAL_SRC_FILES:= \
src/hcidump.c \
parser/avctp.c \
parser/avdtp.c \
parser/bnep.c \
parser/bpa.c \
parser/capi.c \
parser/cmtp.c \
parser/csr.c \
parser/ericsson.c \
parser/hci.c \
parser/hcrp.c \
parser/hidp.c \
parser/l2cap.c \
parser/lmp.c \
parser/obex.c \
parser/parser.c \
parser/ppp.c \
parser/rfcomm.c \
parser/sdp.c \
parser/tcpip.c
LOCAL_SHARED_LIBRARIES := \
libbluetooth
include $(BUILD_EXECUTABLE)
include $(LOCAL_PATH)/bluez/libs/Android.mk
Running ndk-build at APP_ROOT will build binary into libs/armeabi.
Source code of my application can be found here:
https://github.com/d34th4ck3r/Hcidump-in-Android
Here is sample output:
# ./hcidump
