Partly. ;) From the conceptual point of view, the situation is as follows: Linux-zigbee uses the IEEE 802.15.4 MAC mechanisms. This includes the necessity to attach to a PAN to receive a 16 bit address. Contiki uses custom MAC mechanisms for communication which mostly rely on the fact, that all nodes have unique 16 bit addresses. Technically, either Contiki needs to associate to the coordinator (which it currently cannot do, if I am not mistaken) or linux-zigbee needs to learn any of the Contiki MAC mechanisms. I am aware of the fact, that communication is still possible. But I doubt that this is, how the protocols were intended to be used. So the question remains: is there any "specified" way of low-level communication between Contiki and linux-zigbee?
