Master device initiates the discove

Master device initiates the discovery of slave devices within RF range and controls all communications in the piconet.
Slave devices take commands from the master device, e.g., request permission to send (to master device)
master device may grant requests.
Both master and slave devices use the same FHSS channel.
Hopping sequence is unique for each piconet and determined by the master.
All devices change frequencies simultaneously and in the same hopping sequence.
Each slave is synchronized with the clock of the master.
