Enabling wireless tools on Android

Question

I need to use commands like iwconfig in Android, I know I have to install the wireless tools because they are not in Android by default, The problem is that I have just seen 3 chinesse tutorials that makes no sense when I translate them, and a link that downloads a directory with Android wireless tools, but I don't know what to do to get them into my device and use them.

Any help would be apreciated.

Answer 1

1. Download wireless_tools.30.pre9.tar.gz. This version supports non-ASCII char in ESSID.

2. Unpack it into mydroid/external/wireless-tools directory.

3. Create Android.mk file with the following content:

   LOCAL_PATH:= $(call my-dir)
   ################## build iwlib ###################
   include $(CLEAR_VARS)
   LOCAL_SRC_FILES := iwlib.c
   LOCAL_CFLAGS += -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wpointer-arith -Wcast-qual -Winline -MMD -fPIC
   LOCAL_MODULE:= libiw
   LOCAL_STATIC_LIBRARIES := libcutils libc libm
   include $(BUILD_STATIC_LIBRARY)
   ################## build iwconfig #################
   include $(CLEAR_VARS)
   LOCAL_SRC_FILES := iwconfig.c
   LOCAL_CFLAGS += -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wpointer-arith -Wcast-qual -Winline -MMD -fPIC
   LOCAL_MODULE:= iwconfig
   LOCAL_STATIC_LIBRARIES := libcutils libc libm libiw
   #LOCAL_FORCE_STATIC_EXECUTABLE := true
   LOCAL_MODULE_PATH := $(TARGET_OUT_OPTIONAL_EXECUTABLES) # install to system/xbin
   #LOCAL_UNSTRIPPED_PATH := $(TARGET_ROOT_OUT_UNSTRIPPED)
   #LOCAL_MODULE_TAGS := eng user
   include $(BUILD_EXECUTABLE)
   ################## build iwlist ###################
   include $(CLEAR_VARS)
   LOCAL_SRC_FILES := iwlist.c iwlib.h
   LOCAL_CFLAGS += -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wpointer-arith -Wcast-qual -Winline -MMD -fPIC
   LOCAL_MODULE:= iwlist
   LOCAL_STATIC_LIBRARIES := libcutils libc libm libiw
   #LOCAL_FORCE_STATIC_EXECUTABLE := true
   LOCAL_MODULE_PATH := $(TARGET_OUT_OPTIONAL_EXECUTABLES) # install to system/xbin
   #LOCAL_UNSTRIPPED_PATH := $(TARGET_ROOT_OUT_UNSTRIPPED)
   #LOCAL_MODULE_TAGS := eng user
   include $(BUILD_EXECUTABLE)
   

4. Modify it as follows:

   • Change wireless.22.h to be wireless.h ;
   • Modify ifrename.c , add getline() function. You can get the code from external/genext2fs/genext2fs.c ; Notice that this file uses macro to pass another function to getline() .
   • Modify iwlib.h , change #include to be #include . [You might need to check the original file to know what the author means]

5. Compile

   ~/eclair-21/external/wireless-tools$ . ../../build/envsetup.sh
   ~/eclair-21/external/wireless-tools/wireless-tools$ mm
   

6. Copy files to the system

   ~/eclair-21/external/wireless-tools$ croot
   ~/eclair-21$ cp out/target/product/generic/system/xbin/iwconfig /nfs/rootfs/system/xbin/iwconfig
   ~/eclair-21$ cp out/target/product/generic/system/xbin/iwlist /nfs/rootfs/system/xbin/
   

7. Test After starting Android:

   # modprobe libertas
   # modprobe libertas_sdio
