Architecture

Bluetooth defines two of networks

Piconet:

• The piconet can be understood as small adhoc network of devices. Normally 8 stations.
• It has following features
  1. One station known as Master station & other are slave station.
  2. All slaves station synchronize where clock with the master .
  3. One to One or One to Many communication possible.
  4. There may be one station in Parked State.
  5. Each Piconet has unique pattern / id.
  6. Each master can connect 7 simultaneous slaves per piconet.

Scatternet:

By making one slave as the master of piconet, scatternet is formed by combining several piconet:

1. A Scatternet is the linking of multiple co located piconet through the sharing of master & slaves devices.
2. A devices can be both a master & slave.
3. High capacity system.
