CC2500’s operation states contain: Sleep State, Idle State, Active State

Sleep State is the lowest power mode.

After wake up from Sleep State, the module get into Idle State. Except the Sleep State, each state can be switch by

SPI interface, also programmed to auto-switch. CC2500’s radio control state diagram is shown as below, for detail

information in the CC2500 datasheet.
