# WM_GetDispersionBeaconPeriod

## Syntax

      #include <nitro/wm.h>

      u16 WM_GetDispersionBeaconPeriod( void );

## Arguments

None.

## Return Values

Returns the beacon period that should be set by the parent for wireless communications.

## Description

Gets the beacon period (in ms) that should be set for wireless communications when NITRO begins communications as the parent. If multiple parents communicate using the exact same beacon period, it may take the child a long time to detect a number of parents with the `WM_StartScan` function. To prevent conflicts, this function passes appropriately dispersed beacon periods.
