HOWTO: Bluetooth Keyboard/Mouse working with "Master" on ADP1 Howard M. Harte Mon Jan 19 03:02:49 2009

I've been wanting to be able to use a Bluetooth Keyboard and Mouse
with my Android Phone for a while now.  I was able to get it to work
for an ADP1 phone, using the master branch.  The RC29 kernel does not
have proper support compiled in for this to work, so you'll have to
follow the instructions for installing "Master" on your ADP1.  Note
the warnings in the following link, and note that "Master" has some
bugs, so this is only for experimentation, and I wouldn't recommend it
if you use your G1 as your primary phone.

You may also need to do some tricks to get BT running on Master:

1. preserve the BT firmware (brf6300.bin) from your G1:

2. while the phone is booting, "adb shell" and issue the following:
# echo 1 > /sys/class/rfkill/rfkill0/state

How to get HID Keyboard/Mouse working with G1/ADP1 and Master Branch

0. get and build the latest Master version of Android for your ADP1:

1. Create Android.mk in <droid>/external/bluez/hidd:

LOCAL_PATH:= $(call my-dir)

#
# hidd
#

include $(CLEAR_VARS)

LOCAL_SRC_FILES:= \
        main.c \
        sdp.c \
        fakehid.c

LOCAL_CFLAGS:= \
        -DVERSION=\"3.36\" \
        -DSTORAGEDIR=\"/tmp\" \
        -DNEED_PPOLL

LOCAL_C_INCLUDES:= \
        $(call include-path-for, bluez-libs) \
        $(call include-path-for, bluez-utils)/common

LOCAL_SHARED_LIBRARIES := \
        libbluetooth

LOCAL_STATIC_LIBRARIES := \
        libbluez-utils-common-static

LOCAL_MODULE_PATH := $(TARGET_OUT_OPTIONAL_EXECUTABLES)
LOCAL_MODULE_TAGS := eng
LOCAL_MODULE:=hidd

include $(BUILD_EXECUTABLE)

2. Then, make, and download to your ADP1:
$ make
$ fastboot -w -p dream flashall

Note: to get back to RC29, you need an RC29 update.zip on a MicroSD
card, and you need to fastboot -w (to wipe all local data) before
using the recovery mode to re-flash update.zip.  If you don't wipe the
local data, Android will get stuck at the robot screen.

Boot up the phone, and ADB shell into it.
==================================================
$ adb shell
# hcitool scan

        00:23:6C:C2:AA:BB       Mighty Mouse
        00:1B:63:FA:CC:DD       Apple keyboard

Now, in the Settings->Wireless Controls->Bluetooth Menu, pair with
your keyboard and mouse.  Then,

# hidd --connect 00:23:6C:C2:AA:BB
# hidd --connect 00:1B:63:FA:CC:DD

Note the two new input devices on event5 and event6!  The keyboard and
mouse should now work.

TODO: create keyboard map for the keyboard, so all the keys work as
expected.
TODO: Mouse pointer.  It would be really nice if Android supported a
mouse pointer, to emulate a touchscreen, sort of like the emulator
does.
