Reviewing Capture Session Events#
The following figure shows part of a capture session, where events 16 through 23 make a single Association transaction (shown in detail in the following table). The transaction begins with a node's request to a coordinator node to join its network. Each message is paired with an 802.15.4 acknowledgement from the message recipient. The transaction ends when the requesting node acknowledges receipt of the coordinator's Association response:
Event | Summary | Description |
---|---|---|
16 | Association request | Node requests permission to join the network from the network coordinator |
17 | 802.15.4 Ack | Coordinator acknowledges message receipt |
19 | Data request | Node requests network data |
20 | 802.15.4 Ack | Coordinator acknowledges message receipt |
22 | Association response | Coordinator permits joining |
23 | 803.15.4 Ack | Node acknowledges message receipt |
The toolbar's link connectivity button lets you view connections between network nodes. The connectivity diagram shows cumulative connections up to the current event. The following figure shows connections that were established between the network's three-nodes as of Event 52:
