Introduction

Bluetooth Low Energy Enabler for Nexus 7 and 10 installer

This is the project I use to generate:

• https://play.google.com/store/apps/details?id=com.manuelnaranjo.btle.installer2

In order to get a full build you will need an Android AOSP checkout and some patches, this will generate the installer and may reflect the last available binaries.

Building instructions

1. Init repo as AOSP instructions says

2. Copy mnaranjo.xml and busybox.xml into <AOSP>/.repo/local_manifests.xml

3. Run:

    $ repo sync
   

4. Merge projects listed in mnaranjo.xml with upstream ones

5. Run:

    $ source build/envsetup.sh
    $ launch aosp_<model>-userdebug
    $ make busybox bluetooth.default -j 4
    <copy files into app/src/main/assets/ >
   

Packing

Debug APK

<update AndroidManifest.xml>
./gradlew assembleDebug

Release APK

Once you got the debug version tested and running you need to create app/btle.properties with the following structure:

keystore=<path to your keystore>
keystore.password=<keystore password>
keystore.alias=<keystore alias>
key.password=<password for the key to use>

Then you can build the release ready apk with

./gradlew assembleRelease

Old instructions

BusyBox

You need to build busybox in order to get the installer working, once build you should update app/src/main/assets/xbin/busybox, instructions for building are:

git clone https://github.com/sherpya/android-busybox.git
cd android-busybox
cp <BTLE-checkout>/busybox/config .config
patch -p1 < <BTLE-checkout>/busybox/Makefile.lib.patch
make menuconfig # update your ndk paths, add/remove applets
make all V=1
cp busybox <BTLE-checkout>/app/src/main/assets/xbin

AOSP part

Short instructions on how to build the binaries

source build/envsetup.sh
lunch aosp_<model>-userdebug
modify devices/<maker>/<model>/bluetooth/bluedroid_builcfg.h

<copy files>
