NLME_IsAddressBroadcast()

在AF_DataRequest中

if ( ( dstAddr->addrMode == afAddr16Bit ) ||
( dstAddr->addrMode == afAddrBroadcast ) )
{
// Check for valid broadcast values
if( ADDR_NOT_BCAST != NLME_IsAddressBroadcast( dstAddr->addr.shortAddr ) )
{
// Force mode to broadcast
dstAddr->addrMode = afAddrBroadcast;//fhh0606
}

请问什么样的addr.shortAddr 会使NLME_IsAddressBroadcast返回值不等于ADDR_NOT_BCAST ？网络中某个router地址返回值是ADDR_NOT_BCAST 吗？

    enum addr_filter_e  {
      ADDR_NOT_BCAST,     // not a broadcast address
      ADDR_BCAST_NOT_ME,  // broadcast address but not for me based on capabilities
      ADDR_BCAST_FOR_ME   // broadcast for me based on capabilities
    };

    返回ADDR_NOT-BCAST的是如下地址


    enum  bcast_addr_e {
      NWK_BROADCAST_SHORTADDR_RESRVD_F8  = 0xFFF8,
      NWK_BROADCAST_SHORTADDR_RESRVD_F9,
      NWK_BROADCAST_SHORTADDR_RESRVD_FA,
      NWK_BROADCAST_SHORTADDR_RESRVD_FB,
      NWK_BROADCAST_SHORTADDR_DEVZCZR,            // 0xFFFC: Routers and Coordinators
      NWK_BROADCAST_SHORTADDR_DEVRXON,            // 0xFFFD: Everyone with RxOnWhenIdle == TRUE
                                                  // 0xFFFE: Reserved (legacy: used for 'invalid address')
      NWK_BROADCAST_SHORTADDR_DEVALL     = 0xFFFF
    };
