Figure 34b—Flow diagram of Discovery state Configuration state The Configuration state is the second step during network setup. It is also used for network reconfiguration. In the Configuration state, the superframe contains only the timeslot for the beacon described in and two management timeslots, one downlink and one uplink as described in If a device received a beacon indicating configuration state, it tries to get access to the transmission medium in the uplink management timeslot in order to send a Configuration Status frame to the LLDN PAN coordinator. The Configuration Status frame is described in . The Configuration Status frame contains the current configuration of the device. The new device shall repeat sending the Configuration Status frame until it receives a Configuration Request frame for it or the Configuration state is stopped by the LLDN PAN coordinator. The Configuration Request frame is described in . The Configuration Request frame contains the new configuration for the receiving device. After successfully receiving the Configuration Request frame, the device sends an acknowledgment frame to the LLDN PAN coordinator. The acknowledgment frame is described in . Figure 34c illustrates the Configuration state. LLDN Coordinator LLDN Device Start Synchronize and Beacon prepare Status state Frame that contains the current device Configuration Status configuration Received a Frame Beacon Configuration Status Resynchronizes Configuration Request Frame, Received the Prepare Frame Beacon Configuration Request Configuration Frame with Request Ack Frame the new configuration, Frame prepare Ack Frame Resynchronizes
