1 Why install Bluez5.8+?

Bluez is the host part stack running in Linux. Install the Bluetooth LE feature supported Bluez was really important during develop the Bluetooth le apps, it can run your test case on your Linux PC at least. But Why Bluez 5.8 and later version? The Bluez stack was developed so quickly during the past one years from 4.100 to 5.9, its source code's quality was really promoted a lot after those frequent releases. What's more, Bluetooth LE was officially supported after Bluez 5.0 release not just experimental features in the older version. 

The mainly Linux distribution's Bluez version, like Ubuntu13.2 or Fedora 19, still remained in 4.101, which means Bluetooth LE still in the experimental stage at the latest Linux distribution system.

2 Install Bluez5.8 into Linux distribution

Requirement: 

Kernel > 3.5
libusb-dev 
libdbus-1-dev
libglib2.0-dev
libudev-dev
libical-dev
libreadline-dev

Compile and install from the latest source code: 

./configure --prefix=/home/zxsu/software/bluez \
--exec-prefix=/home/zxsu/software/bluez --enable-debug \
--enable-library --enable-test --enable-experimental --disable-systemd \
--with-dbusconfdir=/home/zxsu/software/bluez/dbus/  --with-udevdir=/home/zxsu/software/bluez/udev/

make

make install

3 How to start the newest Bluez stack daemon?

  • stop the system's default bluez daemon. 
# for ubuntu's traditional init services management system
sudo /etc/init.d/bluetooth stop

# for Fedora's latest systemd serverces management system
sudo systemctl stop bluetooth
  • start your latest bluez daemon 
cd $(install_path)/libexec/bluetooth/
sudo ./bluetoothd -n -d
  • enable and test your bluez's ble feature 
cd $(install_path)/bin/
# power up your hci0 device, if your have the only one 
# bluetooth adapter in your pc
./hciconfig hci0 up
./hciconfig hci0

### here is what you get.
#hci0:  Type: BR/EDR  Bus: USB
#   BD Address: 00:1A:7D:DA:71:07  ACL MTU: 310:10  SCO MTU: 64:8
#   UP RUNNING PSCAN 
#   RX bytes:1073 acl:0 sco:0 events:54 errors:0
#   TX bytes:1068 acl:0 sco:0 commands:53 errors:0

./hciconfig hci0 leadv 0

 Now, you can scan Bluetooth le devices from your Bluetooth smart ready phones like Google Nexus 4 with android 4.3 system which has an app source code located in its sdk-18's sample code -- $(SDK)/samples/android-18/legacy/BluetoothLeGatt
or, you can search Bluetooth low energy keywords in google play markets, and install one. I installed both apps into my Google Nexus 4.

Bluedroid stack in android

Bluedroid stack in android Table of Contents Bluetooth stack in android Bluedroid .VS. Bluez Porting guide of Bluedroid stack 1 Bluetooth stack in android From Android 4.2, google use Bluedroid stack as its default Bluetooth host stack, before android 4.2, its default Bluetooth host stack was Bluez, which is also the Linux distribution's default stack. So why google changed its Bluetooth stack? The reason is maybe that Bluez stack was designed for the desktop environment, so in order to port Bluez into android, android must solve some dependency issues, like porting Dbus, Linux desktop's default IPC, into android. So there are at least five processes to power Bluetooth before android 4.2, they are systems, Bluetooth APP, Bluez, hciattach, and Dbus. The damn thing is that there are bugs between them, so Bluetooth stack is the weakest part in the android system before android 4.2, yeah, it is the usual reason that android system corrupted. So, what's t

How to setup an NAT server? Table of Contents What is NAT? How to setup NAT host? a shell script from vbird's book 1 What is NAT? NAT stands for Network Address Transition, which is the basic function of gateway host. I try to hack Bluetooth tethering module in android this week, it include the Bluetooth Pan profile and the NAT setup process, which means in order to implement the Bluetooth tethering, first, two devices must be connected by Bluetooth Pan profile, and then the server part device acted as gateway host to supply the network forward service. In other words, after Bluetooth Pan profile connected, the server must to setup its NAT rules to forward the IP packages. So how to setup NAT rules? 2 How to setup NAT host? My memory is still fresh that at the start of my Linux journey, I setup my Linux desktop as an NAT host to provide Internet services for my lab's classmates. During the days as a programmer, I once did a job to hacking android&

Network programming in elisp

  Network API in elisp Table of Contents 1 Introduction 2 A example 3 Http server implemented by elisp 1 Introduction Emacs is not just an editor, Yes, that's true. Emacs lisp can do network connection programming by its network API. But there is something difference with other kinds of programming language. First, elisp do not support multi-thread, pretty cool, huh!! Yeh, Multi-threads programming is a horrible venture for you, right! Second, There is no socket similarly conception in elisp, and elisp provide network programming ability as processes. Elisp can open a network connection by function – open-network-stream .  It can make network connection server listen a special port by function - make-network-process . Both of those function return a process object. Then you can communicate with the process by process's API. 2 A example I write a snippet code to figure out How to use it.
