rgrover1 710:b2e1a2660ec2 967 * Radio Notification is a feature that enables ACTIVE and INACTIVE
rgrover1 710:b2e1a2660ec2 968 * (nACTIVE) signals from the stack that notify the application when the

rgrover1 710:b2e1a2660ec2 970 *
vcoubard 1048:efb29faf12fc 971 * The ACTIVE signal is sent before the radio event starts. The nACTIVE

rgrover1 710:b2e1a2660ec2 973 * by the application programmer to synchronize application logic with radio
rgrover1 710:b2e1a2660ec2 974 * activity. For example, the ACTIVE signal can be used to shut off external
vcoubard 1048:efb29faf12fc 975 * devices, to manage peak current drawn during periods when the radio is on,
rgrover1 710:b2e1a2660ec2 976 * or to trigger sensor data collection for transmission in the Radio Event.
