Hi,

When we make the group control, we found the muticast flag is always 0, not 1. Any setting for this flag in Z-Stack? We use the stack Z-Stack Lighting 1.0.2.

Best Regards!

You can refer to the following descriptions from Zigbee spec

The multicast flag field of the NWK header will be set according to the value of the DstAddrMode parameter.
If the DstAddrMode parameter has a value of 0x01, the NWK header will contain a multicast control field whose
fields will be set as follows:
• The multicast mode field will be set to 0x01 if this node is a member of the group specified in the
DstAddr parameter.
• Otherwise, the multicast mode field will be set to 0x00.
