Raspberry Pi

Due to its small size, low price and power consumption and its general extensibility the Raspberry Pi (or any other similar device) is considered an interesting platform for projects related to the Internet of Things.

Examples of use to come so stay tuned!

Updating BlueZ

The version of BlueZ available for standard distributions for a Raspberry Pi such as Raspbian, may be old (prior to version 5) and thus incapable of handling Bluetooth LE well, if at all. It is therefore strongly recommended to install the most recent version, using a procedure like the one below (compiling BlueZ on the Raspberry Pi itself takes about 20-30 minutes):

sudo apt-get --purge remove bluez
sudo apt-get update
sudo apt-get install libusb-dev libdbus-1-dev libglib2.0-dev libudev-dev libical-dev libreadline-dev
wget https://www.kernel.org/pub/linux/bluetooth/bluez-5.24.tar.xz
tar xf bluez-5.24.tar.xz
cd bluez-5.24
./configure --prefix=/usr --enable-library --disable-systemd
make
sudo make install
sudo cp attrib/gatttool /usr/bin
