What are the types of Bluetooth networks

There are mainly 2 types of bluetooth network first is Master and second is Slave.


When many bluetooth devices are connected in the network, then one device is primary or master device and all other devices are secondary or slave devices. There are mainly 2 types of networks in bluetooth.

  1. Piconet
  2. Scatternet


Picket network is formed when one master device and one slave device or one master device and many slave devices are present in piconet there can be maximum 7 active slaves, so it has maximum 8 devices i.e. one master device and 7 Slave device can be added which device initiates the connection and other devices join the network started by it then that device is called master device because Piconet has only one master device which can send data to other device. So communication between master and slave device can be One to One or One to Maney In One to One when master device send data then only one slave device can receive data and in One to Maney communication when master device send data. If it happens then more than one Slave Device can receive.


Multiple Piconets is called Scatternet The same device which is a Slave device in one Piconets can act as Master Day in Piconets in another device because of this reason one device is part of 2 Piconets but more than one device has Master Device in Piconets As you know, Scatternet is prepared by connecting more than one Piconets, if a device is a Slave device in any Piconets and Master device in other Piconets, then the data or message received from that Piconets in which it is Slave. You can send data to your Slave Device in other Piconets in which it is the master device.
