/**
 * Implement beam detection and reception algorithms.
 * It will take care of all configuration and radio setup to
 * detect and receive beams in the current Z-Wave region.
 * If a beam is detected, RAIL will provide
 * the usual \ref RAIL_EVENT_ZWAVE_BEAM event, during which time users can
 * process the beam as normal. However, normal packets may also be
 * received during this time (thus triggering \ref RAIL_EVENTS_RX_COMPLETION
 * events), in which case, this API may need to be re-called to receive
 * a beam. Users should also listen for
 * \ref RAIL_EVENT_RX_CHANNEL_HOPPING_COMPLETE which will indicate
 * that no beam is heard at which point the radio will be automatically idled.
 * Until one of these events are received, users should not try to attempt to
 * reconfigure radio settings or start another radio operation. If an application
 * needs to do some other operation or configuration, it must first call
 * \ref RAIL_Idle and wait for the radio to idle.
 *
 * @note: The radio must be idle before calling this function.
 *
 * @note: \ref RAIL_ConfigRxChannelHopping must have been called successfully
 * in Z-Wave before this function is called to provide a valid memory buffer
 * for internal use (see \ref RAIL_RxChannelHoppingConfig_t::buffer).
 *
 * @note: This function alters radio functionality substantially. After calling
 * it, the user should call \ref RAIL_ZWAVE_ConfigRegion,
 * \ref RAIL_ConfigRxChannelHopping, \ref RAIL_EnableRxChannelHopping,
 * and \ref RAIL_SetRxTransitions to reset these parameters to whatever
 * behaviors were desired before calling this function. Additionally,
 * this function will idle the radio upon on exit.
 *
 * @param[in]  railHandle A RAIL instance handle.
 * @param[out] beamDetectIndex Indicator of whether or not a beam was detected
 * at all, regardless of if it was received, generally for use only by instruction
 * from Silicon Labs. Can be NULL.
 * @param[out] schedulerInfo While Z-Wave is currently not supported in
 * RAIL Multiprotocol, this scheduler info is added to future proof
 * against any future version of multiprotocol which may support it. For now,
 * this argument can be NULL.
 *
 * @return status indicating whether or not the radio was able to configure
 * beam packet detection/reception. Reasons for failure include an un-idled
