Node Discovery from Device Cloud to XIG failed

[Xian Lin Song]

When using Device Cloud API Explorer to do a Examle -> SCI -> RCI -> XBee -> Discovery Nodes, (I am using 802.15.4 though, not zigbee module)

<sci_request version="1.0">

        <discover/>

      </do_command>

    </rci_request>

The response is

I encountered the below error in the XIG console:

cp4pc.rci - Received do_command request

Traceback (most recent call last):

  File "./library/ext/cp4pc/rci/model/device.py", line 153, in handle_xml

However, if using Example->SCI->Python Callback to implement a "Node Discovery" AT Command "ND"

If issue "NI" the response is OK and I can see my "NI" value in value field

May I know how to do the node discovery from Device Cloud via XIG?

[Xian Lin Song]

I found the reason is at the line 110 of file

vi library/ext/cp4pc/rci/controller/zigbee.py

 Comment out the line 110 which is "addr_parent"

            ET.SubElement(device, 'type').text = self.TYPE_CONVERSION.get(node.type, '0')

            ET.SubElement(device, 'ext_addr').text = node.addr_extended[1:-2].lower()+'!' #remove '[' and ']'

            ET.SubElement(device, 'net_addr').text = '0x'+node.addr_short[1:-2].lower()

            # ET.SubElement(device, 'parent_addr').text = '0x'+node.addr_parent[1:-2].lower()

Now it gives me correct response, of course without parent address. Need time to look into the code and fix this "int" and "list" conflict ( error due to python treat the node.addr_parent[1:-2] as an int, not list]

No permanent fix yet... Will update if I found one. Or if someone can contribute to the source code and fix this error, I will be appreciated.

Or maybe because the remote XBee is a 802.15.4 not Zigbee, it has no parent so parent address is an INT not a LIST???
