I am using the Monitor and Test API to control a CC2520 running the ZigBee Coordinator sample from a PC via the serial port. I have the "Z-Stack Monitor and Test API" document (SWRA198).
I am seeing an MT AREQ message with a Cmd0 == 0x45 (ZDO AREQ) and a Cmd1 == 0xC3. My document describes ZDO Cmd1 values up to 0xC2 and no further. Can anyone tell me what Cmd1 code 0xC3 indicates?
---------------------------
Here is my request message: FE 05 25 04 00 00 00 00 0A 2E. This is a ZDO_SIMPLE_DESC_REQ attempting to get information about the coordinator (NetAdx=0000).
Here is my response: FE 05 45 C3 94 F0 01 68 90 1E. It appears to reference network addresses F094 and 9068, both of which are actual nodes on the network. But what the C3 means, and why I am getting this message, (apparently) in response to a ZDO_SIMPLE_DESC_REQ addressed to 0000, I don't understand.
(The message I'm seeing might not be in response to the ZDO_SIMPLE_DESC_REQ, but in that case I'm seeing the mystery message above, and I'm not seeing any response to my ZDO_SIMPLE_DESC_REQ.)
OK, looking through the forum some more I found "Questions on relationship between ZNP and Z-stack MT interface", which gave me enough information to suggest that what I'm seeing is a ZDO_SRC_RTG_IND message. I still don't know where the expected response to my ZDO_SIMPLE_DESC_REQ went.
