 What is Scatternet?

Eight devices can be connected in a Bluetooth network called PICONET. One of them acts as a master and the others act as slaves.

Must Read>> About PICONET

A scatternet is formed when two or more piconets connect through a bridge node as shown in the image.

In addition to the seven active slaves, there can be up to 255 parked nodes in the net that can only respond to a beacon signal from the master. 

The slaves are dumb devices that do the task that the master tells them to do.

The piconet is a TDM system with the master controlling the clock and determining which slave gets to communicate in which time slot. 

All the communication is between the master and slave and not between the slaves.
