bluez のインストール

zypper install bluez bluez-devel

https://git.kernel.org/pub/scm/bluetooth/bluez.git

python モデュールのインストール

zypper install pybluez boot_python3
pip3 install gattlib 
 ## pip3 install pybluez[ble]  // どっちが正しい??
( boot_python-py34 がないとエラーが出るので
  cd /usr/lib64/ 以下で探す
  boot_python-py3 を
  ln -s boot_python-py3 boot_python-py34 )
pip3 install bluepy
