Piconets<br />
Nodes can assume the role of master or slave<br />
One or more slaves can connect to a master, forming a piconet<br />
The master sets the hopping pattern for the piconet, and all<br />
slaves must synchronize to that pattern: All units share the same<br />
channel<br />
Maximum of 7 slaves controlled by a master (How many<br />
address bits are required?)<br />
<strong>Bluetooth</strong> radios are symmetric - same device can act as both<br />
master and slave<br />
Slaves are not allowed to talk to each other directly<br />
Other operational states (low power)<br />
Parked: Device does not participate in the piconet,<br />
synchronized to the master and can be quickly reactivated<br />
Standby: Device does not participate in the piconet,<br />
occasionally monitoring, not synchronized
