Bluetooth technology protocols are allowed from one master device to interconnect with seven active devices for communication purpose. A master Bluetooth device can connect to seven devices with the Bluetooth master device in a wireless network. This kind of network with 8 devices is called a piconet. A piconet is an ad-hoc computer network and it can be inactive, which is the master device for all active status at any time. The transfer of data can be between the master and one other device. These devices can switch roles and the slave has a privilege to become the master at any time. The master switches from one device to another in a round-robin fashion. Simultaneously the transmission from the master to multiple other devices is possible. It allows connecting more piconet together to form a scatter net. Some devices act as a bridge by playing the master in one piconet and a slave role in another. Any device may perform an inquiry to find other devices to connect to and any device can be configured to respond to such inquiries. If the device is trying to connect to the address of the device, it always responds to the connection requests and transmits the information. Some devices can be connected to only one device at a time and connecting to them. It prevents them from connecting to other devices and appearing in inquiries until they disconnect from the other device.
