2. The data transmission in Bluetooth works via a 2.4 GHz radio connection. For this it is necessary that TV respectively adapter and speakers have a corresponding chip installed.
3. Once Bluetooth has been activated on both devices, a Wireless Personal Area Network is created, which is also called Piconet. If several Bluetooth devices are connected to a TV, then they are slaves. The TV is referred to as the master, whereby this can control the communication with the other devices via the piconet.
