zigbee协议栈通信时能否实现一个节点加入多个组

zigbee协议栈通信时能否实现一个节点加入多个组，一个节点能否在多个组中

可以的。您可以参考ZigBee.Wireless.Networks.and.Transceivers的第3.4.2

A device can be a member of more than one multicast group.

具体如何实现呢？和加入一个数组时一样吗？再添加一个就行吗？

SampleApp_Flash_DstAddr.addrMode = (afAddrMode_t)afAddrGroup;
  SampleApp_Flash_DstAddr.endPoint = SAMPLEAPP_ENDPOINT;
  SampleApp_Flash_DstAddr.addr.shortAddr = SAMPLEAPP_FLASH_GROUP;
  
  SampleApp_Flash_DstAddr2.addrMode = (afAddrMode_t)afAddrGroup;
  SampleApp_Flash_DstAddr2.endPoint = SAMPLEAPP_ENDPOINT;
  SampleApp_Flash_DstAddr2.addr.shortAddr = SAMPLEAPP_FLASH_GROUP2;

  // By default, all devices start out in Group 1
  SampleApp_Group.ID = SAMPLEAPP_FLASH_GROUP;//0x0001;
  osal_memcpy( SampleApp_Group.name, "Group 1", 7  );
  aps_AddGroup( SAMPLEAPP_ENDPOINT, &SampleApp_Group );
  
  SampleApp_Group2.ID = SAMPLEAPP_FLASH_GROUP2;//0x0004;
  osal_memcpy( SampleApp_Group2.name, "Group 2", 7  );
  aps_AddGroup( SAMPLEAPP_ENDPOINT, &SampleApp_Group2 );
