Here is a little more detail and better explanation to my original posting -----
I am working on an ZigBee SE experiment using 2 XBEE-S2 modules with the
following configuration and tools -
Xbee Modules -
1) XBEE-S2 setup using the Coordinator API Function set under XB24-ZB FW: 21A7
2) XBEE-S2 setup using the Router API Function Set under XB24-ZB FW: 23A7.
Tools-
1) MicroChip sniffer with provided sniffer application
2) ATMEL RZUSBSTICK with killerbee firmware
3) Wireshark
4) XBEE-API
----------------
The intent here is to generate a link key using the link key generation using
MMO and CRC checks as defined in the SE Profile Specification. Have the
Router/SED send a join request to the Coordinator and have the Coordinator
verify the request using the same Link Key. Once verified the Network Key is
encrypted using the Link Key and sent to the Router/SED who in turn will
decrypt and start comms using the network key.
So far I have been able to successfully implement the Link Key establishment
mechanism to include the validation of an Installation code with CRC and MMO
for generating the Link Key, assigning the link key to the SED and providing
the link key to the coordinator in anticipation of a Join Request.
I was under the impression that once the Link Key was generated and written to
both the Coordinator and the Router/SED that the XBEE firmware function set
would take over from there and automatically send an encrypted join request to
the Coordinator using the Link Key who would in turn decrypt, verify and send
the Network key encrypted using the link key to the Router/SED who would then
decrypt, assign to itself and start comms, however it seems like this is not
the case. I have two sniffers running - the MicroChip Sniffer and the Atmel
RZUSBSTICK (using the killerbee firmware piping traffic through a named piped
to Wireshark) - and neither detect anything other than a broadcast from the
coordinator.
I've looked through the XBEE-API and I haven't found anything that would
facilitate initiating a join request to the coordinator; or maybe I have over
looked it.
Has anyone been able to implement a join request with either clear or encrypted
comms?
Thanks in advance ...
