For nRF Thread Topology Monitor to attach the nRF device to the Thread network and
send OpenThread CLI commands over serial port, the nRF device must be programmed with the
OpenThread CLI example that is included in the the nRF Thread Topology Monitor package as a
hexadecimal file.
To set up an nRF52840 DK, nRF52833 DK, or nRF52840 Dongle, complete the following
steps:
If the nRF device is the first device to join the Thread network, it becomes the
Leader, as shown in the following figure:
Figure 4. First Thread Leader is connected
At this point, other Thread devices attach themselves to the network.
If there already are devices in the Thread network, the nRF device joins as an End
Device, and then becomes a Router within the network.
Eventually, nRF Thread Topology Monitor displays a topology that is similar to the
following figure:

You can interact with the topology nodes in the following
ways:
- Use the mouse scroll to zoom in and zoom out of the network
topology.
- Press the left mouse button and move the mouse around to move the
network topology in the same direction.
- Click a node to select it and drag it to a different location within
the topology view while keeping the left mouse button
pressed.
- Click a node to see its particular connections, which will appear as
bolded out in the topology view upon selection.
- Click a node to see its parameters in the Device parameters
panel.
- After selecting a node, modify the device name label or ping the
device using options in the Device parameters panel. See Device parameters for more
information.
