rgrover1 710:b2e1a2660ec2 964 * Radio Notification is a feature that enables ACTIVE and INACTIVE
rgrover1 710:b2e1a2660ec2 965 * (nACTIVE) signals from the stack that notify the application when the
rgrover1 753:0f60274cd3ad 966 * radio is in use.
rgrover1 710:b2e1a2660ec2 967 *
vcoubard 1048:efb29faf12fc 968 * The ACTIVE signal is sent before the radio event starts. The nACTIVE
vcoubard 1048:efb29faf12fc 969 * signal is sent at the end of the radio event. These signals can be used
rgrover1 710:b2e1a2660ec2 970 * by the application programmer to synchronize application logic with radio
rgrover1 710:b2e1a2660ec2 971 * activity. For example, the ACTIVE signal can be used to shut off external
vcoubard 1048:efb29faf12fc 972 * devices, to manage peak current drawn during periods when the radio is on,
rgrover1 710:b2e1a2660ec2 973 * or to trigger sensor data collection for transmission in the Radio Event.
