After joining the network, nRF Thread Topology Monitor starts to periodically
retrieve the current list of Routers to ensure that the topology displays all nodes that you
can interact with.
Each Router is polled using Thread's standard diagnostic messages
(MGMT_DIAG.req). In response, Routers in the network send
their current link set (for the currently connected neighbors), child table, and
basic network parameters, such as network address or extended MAC address.
Eventually, nRF Thread Topology Monitor displays a topology that is similar to the
following figure:
Figure 1. Topology panel with Thread nodes
To interact with a Thread topology node:
-
In the topology panel, select the node that you want to interact with by
clicking on it.
The node connections to other nodes will be bolded out and the
Device parameters panel will be updated with
information about the node.
-
In the Device parameters panel, click the
Ping/Identify button to send a ping to the selected
Thread device.
Note: If the
Thread device uses the Thread BSP module, LEDs on this device start
blinking.
-
In the Device parameters panel, change the name of the
node in the Device Name and click the Change
Name button.
The name of the device will be changed in the topology view and saved to
PC.
When you are done interacting with the nodes, click the
Stop scan button in the Discovered
devices panel to stop scanning the topology and clear the topology
view.
