Use tools listed on this page to test Matter samples and develop Matter applications in the nRF Connect SDK.
To build and develop Matter applications, you need the GN meta-build system. This system generates the Ninja files that the nRF Connect SDK uses.
If you are updating from the nRF Connect SDK version earlier than v1.5.0, see the GN installation instructions.
The Matter controller is a role within the Matter development environment. The controller device is used to pair and control the Matter accessory device remotely over a network, interacting with it using Bluetooth LE and the regular IPv6 communication.
The following figure shows the available Matter controllers in the nRF Connect SDK.
See the Configuring Matter controller page for information about how to build and configure the Matter controller.
Because Matter is based on the Thread network, you can use the following Thread tools when working with Matter in the nRF Connect SDK.
The Thread Border Router is a specific type of Border Router device that provides connectivity from the IEEE 802.15.4 network to adjacent networks on other physical layers (such as Wi-Fi or Ethernet). Border Routers provide services for devices within the IEEE 802.15.4 network, including routing services for off-network operations.
See the Thread Border Router documentation for configuration instructions.
The nRF Sniffer for 802.15.4 is a tool for learning about and debugging applications that are using protocols based on IEEE 802.15.4, like Thread or Zigbee. It provides a near real-time display of 802.15.4 packets that are sent back and forth between devices, even when the link is encrypted.
See nRF Sniffer for 802.15.4 for documentation.
nRF Thread Topology Monitor is a desktop application that connects to a Thread network through a serial connection to visualize the topology of Thread devices. It allows you to scan for new devices in real time, check their parameters, and inspect network processes through the log.
See nRF Thread Topology Monitor for documentation.
