On Linux®, you want to know if your Bluetooth® adapter is Bluetooth Low Energy 4.0 compatible.
To find the version of Bluetooth adapter on your Linux, open the terminal and use this command:
sudo hcitool -a
Find LMP Version. If the version is
0x6 or higher, your system is compatible with
Bluetooth Low Energy 4.0. Any version lower than that indicates an older
version of Bluetooth.
