Interacting with a Thread topology node

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:

1. 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.
2. 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.
3. 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.
