I have tried the following commands in ZGC TOOL:

ZBHCI_CMD_DISCOVERY_ACTIVE_EP_REQ
ZBHCI_CMD_DISCOVERY_NODE_DESC_REQ
ZBHCI_CMD_DISCOVERY_SIMPLE_DESC_REQ

When I enter 0xFFFF in the first field in ZGC TOOL which says "DstAddr unicast", the only response I get is - ZBHCI_CMD_ACKNOWLEDGE

Then I tried to enter the same address that I put in "nwkAddrOfInterest" so message sent is like this:

55 00 13 00 05 19 60 44 60 44 0f aa

This time it works. So "DstAddr unicast" can't be 0xFFFF? So description should be changed - it is confusing.

Is that right?

I tried ZBHCI_CMD_DISCOVERY_MATCH_DESC_REQ

First field is "DstAddr broadcast or unicast"

When I put 0xFFFC there I get:

src_addr:0x6044
status:0x0(ZDO_SUCCESS)
nwk_adds_interest:0x6044

But what should I enter in "InClusterList" and "OutClusterList"?
