hi to every one

Data from a blue tooth device is tranfering by light source?
well i didnt exactly get your question but ill try to explain.
Bluetooth is a radio standard and communications protocol primarily designed for low power consumption, with a short range (power class dependent: 1 meter, 10 meters, 100 meters) based around low-cost transceiver microchips in each device.
Bluetooth lets these devices communicate with each other when they are in range. The devices use a radio communications system, so they do not have to be in line of sight of each other, and can even be in other rooms, so long as the received transmission is powerful enough.
Reply:no - bluetooth uses short range radio frequencies (RF)
