Working with the chip-tool-web

The 'chip-tool-web' is a web-based graphical user interface (GUI) for the Matter controller, designed specifically for i.MX SoC customers. It provides an intuitive interface for commissioning Matter devices, sending Matter messages and performing other Matter-specific actions.

With the chip-tool-web, you can easily configure, manage and monitor Matter devices without the need to use complex command lines.



Source files

You can find the source files for the chip-tool-web in the ${matter}/examples/chip-tool/webui directory, which are separated into frontend and backend components. This allows easy customization and modification based on specific requirements and use cases.


Building and running the chip-tool-web

Before using the chip-tool-web, you must compile it from source on Linux (armv71/aarch64) or macOS.

Note: To ensure compatibility, you should always build the chip-tool-web from the same revision of the connectedhomeip repository.

Building the chip-tool-web

The steps to compile the chip-tool-web are the same as How to build Matter application

After compilation, you will find two binaries, chip-tool and chip-tool-web, in the ${matter}/out/chip-tool-web/ folder. However, please note that the chip-tool binary in this folder may not work as expected. Therefore, it is recommended not to use the chip-tool binary located in the out/chip-tool-web directory.

Running the chip-tool-web

Introduction

Before using chip-tool-web, make sure that the i.MX board is properly connected to the Internet.

Default Setup

The image built by meta-nxp-connectivity includes the chip-tool binary in the i.MX SOC /usr/bin directory, and all frontend files are already copied to /usr/share/chip-tool-web/. Therefore, to use chip-tool-web, you only need to copy the newly compiled chip-tool-web binary to the /usr/bin directory.

Custom Setup

If you want to specify a custom location for the frontend files, you can follow these steps:

  • Copy the frontend file to the desired location:
    $ cp ${matter}/examples/chip-tool/webui/frontend $frontend_path
    
  • Export the CHIP_TOOL_WEB_FRONTEND variable and set it to the path of the frontend files:
    $ export CHIP_TOOL_WEB_FRONTEND=$frontend_path
    
  • If you want to make this variable persistent across sessions, add the above command to your shell configuration file (e.g., ~/.bashrc).

Verification

After completing the setup, run the following command to verify that chip-tool-web is working properly:

$ chip-tool-web

If you see the following log: CHIP:DL: CHIP task running, everything is working fine.

Accessing the chip-tool-web

The chip-tool-web can run on a variety of devices, including desktops, laptops, and mobile devices. To access the chip-tool-web, follow these steps:

  • Open a web browser (such as Chrome, IE, Safari, etc.) on the device you want to use.
  • Enter the IP address of the i.MX board followed by :8889 in the address bar of the browser. You can find the IP address of the i.MX board by running the ifconfig command on the board.
  • You will see the chip-tool-web home page. Follow the instructions in the section to proceed.

Example of opening on an iPhone

Here is an example of opening chip-tool-web on an Apple mobile phone using Safari:

Note: The network connected to the running device must be on the same segment as the i.MX device.

Using chip-tool-web to commission a Matter device

This section provides instructions for using chip-tool-web to commission Matter devices, with a focus on the chip-lighting-app application clusters on i.MX MPU platforms.

It should be noted that while chip-tool-web provides a graphical user interface (GUI) for executing commands through buttons and other visual controls, it does not completely replace the chip-tool command line tool. Users can still use the chip-tool command line tool if they prefer or need to, but chip-tool-web provides an additional option for interacting with Matter devices. The following sections will provide a detailed overview of the features currently available in chip-tool-web.

An official Matter document explaining how to use chip-tool as a Matter controller, can be found here.

For more information on how to use Matter applications on i.MX MPU platforms, see the NXP Matter demos guide.

Using Interactive mode

The chip-tool offers two modes of operation: Single Command Mode and Interactive Mode, each with unique features and appropriate use cases. For detailed information about these modes, please refer to the official documentation available at Interactive mode versus single-command mode.

It should be noted that chip-tool-web uses the Interactive Mode to allow users to conveniently send multiple commands through the web interface and to improve the management of Matter devices.

Pairing a Matter device

To access the Pairing feature in chip-tool-web, first open the navigation bar and select Pairing. This will display the following menu interface:

Alt text

On the pairing page, there are three buttons to select the type of pairing: ONNETWORK, BLE-WIFI, and BLE-THREAD. These buttons allow the user to select the different pairing modes to use. After clicking the appropriate button, the user interface for the selected pairing type will appear.

The remainder of this section provides a detailed overview of each of these pairing methods.

Pairing a device over IP

Click on the ONNETWORK pairing type selection button, the display interface will be as shown below.

Alt text

You should specify a node alias for the node ID so that you can identify it by node alias. If you enter the correct parameters and click the onnetwork button on this interface, the following command will be triggered to discover devices and attempt to pair with the first discovered one using the provided setup code:

$ chip-tool pairing onnetwork-commissioning-mode <node_id> <pin_code>

In this command:

  • <node_id> is the user-defined ID of the node being commissioned.
  • <pin_code> is device specific setup PIN code determined in the step and used to discover the device.

Pairing a device over Ble-WiFi

Click on the BLE-WIFI pairing type selection button, the display interface will be as shown below.

Alt text

You should specify a node alias for the node ID so that you can identify it by node alias. If you enter the correct parameters and click the BLE-WIFI button on this interface, the following command will be triggered to commission the device to the existing WiFI network:

$ chip-tool pairing ble-wifi <node_id> <ssid> <password> <pin_code> <discriminator>

In this command:

  • <node_id> is the user-defined ID of the node being commissioned.
  • <ssid> and <password> are credentials determined in the step.
  • <pin_code> and <discriminator> are device-specific keys determined in the step.

For example:

chip-tool pairing ble-wifi 1 xyz secret 20202021 3840

If you prefer the hexadecimal format, add hex: prefix when entering ssid, password. For example:

$ chip-tool pairing ble-wifi <node_id> hex:<ssid> hex:<password> <pin_code> <discriminator>

Note: The <node_id> can be provided as a hexadecimal value with the 0x prefix.

Pairing a device over Ble-Thread

Click on the BLE-THREAD pairing type selection button, the display interface will be as shown below.

Alt text

You should specify a node alias for the node ID so that you can identify it by node alias. If you enter the correct parameters and click the BLE-Thread button on this interface, the following command will be triggered to commission the device to the existing Thread network:

$ chip-tool pairing ble-thread <node_id> hex:<operational_dataset> <pin_code> <discriminator>

In this command:

  • <node_id> is the user-defined ID of the node being commissioned.
  • <operational_dataset> is the Operational Dataset determined in the step.
  • <pin_code> and <discriminator> are device-specific keys determined in the step.

Note: When entering the <operational_dataset>, there is no need to add the hex: prefix, as this is already added by default in the chip-tool-web backend.

To obtain the Thread network credentials, you can either form the OpenThread network manually by following the instructions provided in the Configure OpenThread Network, or via otbr-web.

Once the network has been formed, you can retrieve the Thread network credentials by clicking the GET-DATASET button in chip-tool-web instead of manually typing the ot-ctl dataset active -x command.

Controlling a Matter device OnOff cluster

Once the pairing process is complete, the Matter device is successfully commissioned to the network. For the lighting application, the On/Off clusters are implemented in chip-tool-web, allowing you to control the end devices using the onoff cluster commands.

To access the onoff function in the chip-tool-web, first open the navigation bar and select OnOff. The following interface will be displayed:

The following will introduce the content of READ button in detail.

Getting the report

After clicking the READ button to trigger the corresponding command, a report will later be displayed in the Get Report section of the page. The page does not clear previously generated reports and always displays the latest report at the top of the list.

Report Format

The report is output in text format with the following structure:

Report from ${nodealias} ${nodeid}:${endpoint}. Cluster:${cluster}
${attribute}:${value}

Report Elements

  • ${nodealias}: The node alias of the device.
  • ${nodeid}: The nodeid of the device.
  • ${endpoint}: The endpoint of the device.
  • ${cluster}: The cluster name to which the device belongs.
  • ${attribute}: The name of the attribute being reported. In this case, the default attribute is On-Off.
  • ${value}: The value of the attribute. There are two possible values: TRUE or FALSE. TRUE indicates that the light is on, while FALSE indicates that the light is off.

Report Examples

The following is an example of a multiple read of a device whose nodealias is Light and nodeid and endpoint are both 1.

Opening the commissioning window for the commissioned Matter device

Multi-admin feature allows you to join Matter device to multiple Matter fabrics and have multiple different Matter administrators administer it. Chip-tool-web supports the Basic Commissioning Method to open the commissioning window of i.MX Matter device for a new administrator from another fabric.

To access the Multi-admin function in the chip-tool-web, first open the navigation bar and select MultiAdmin. The following interface will be displayed:

Alt text

Select the node alias of the paired Matter device, and the page will automatically fill in the corresponding node ID. Then enter the value of windows timeout and click the OPEN COMMISSIONING WINDOW button to trigger the Open Commissioning window:

$ chip-tool pairing open-commissioning-window <node_id> <option> <window_timeout> <iteration> <discriminator>

In this command:

  • <node_id> is the ID of the node that should open commissioning window.
  • <option> is equal to 0 for Basic Commissioning Method.
  • <window_timeout> is time in seconds, before the commissioning window closes.
  • <iteration> is number of PBKDF iterations to use to derive the PAKE verifier.
  • <discriminator> is device specific discriminator determined during commissioning.

Note: The <iteration> and <discriminator> values are ignored because the <option> is set to 0.

You can then commission the Matter device to a new fabric using another instance of the CHIP tool by below cmd or via the onnetwork pairing.

$ chip-tool pairing code <node_id> <payload>

In this command:

  • <node_id> is the user-defined ID of the commissioned node.
  • <payload> is the the QR code payload or a manual pairing code generated by the first commissioner instance when opened commissioning window. Since you are using the Basic Commissioning Method to open commissioning window, the manual pairing code should be 34970112332.

Subscribing a Matter device OnOff cluster

Subscribing to an attribute lets you mirror the state of the attribute as it changes in the Matter network. Chip-tool-web support for subscribing to the on-off attribute of the onoff cluster.

To access the Subscribe function in the chip-tool-web, first open the navigation bar and select Subscribe. The following interface will be displayed:

Alt text

Select the node alias of the paired Matter device, and the page will automatically fill in the corresponding node ID. Then enter the value of windows timeout and click the SUBSCRIBE button to trigger the subscribe command:

$ chip-tool onoff subscribe on-off <min-interval> <max-interval> <node_id> <endpoint_id>

In this command:

  • <min-interval> specifies the minimum number of seconds that must elapse since the last report for the server to send a new report.
  • <max-interval> specifies the number of seconds that must elapse since the last report for the server to send a new report.
  • <node-id> is the user-defined ID of the commissioned node.
  • <endpoint_id> is the ID of the endpoint where the onoff cluster is implemented.

Subscribe Report Format

The subscribe report with the on-off attribute is updated on Subsribe Status section when it changes. The page does not clear previously generated reports and always displays the latest report at the top of the list. The following is an example of the subscription statue of a device whose nodealias is Light and whose nodeid and endpoint are both 1.

Alt text

The report is output in text format with the following structure:

Subscribe Report from ${nodealias} ${nodeid}:${endpoint}. Cluster:${cluster}
${attribute}:${value}

The elements of the subscribe report are the same as those of the OnOff read report.


Note: Because subscribe must maintain the subscription status in interactive mode, please do not enter any other commands in the console of the i.MX Matter devices when the chip-tool-web initiates the subscribe command, as this may interrupt the update of the subscribe report.

Getting status for a commmissioned Matter device

Chip-tool-web stores the node ID and node alias of the paired device in the chip_tool_config.web.ini file. If TMPDIR is not set, the chip_tool_config.web.ini file is located in the /tmp/ directory. If export TMPDIR=${tmpfir} is set, it is stored in the ${tmpfir} directory. You can see the node ID and node alias of all paired nodes in GetStatus tab, and you can delete the paired node information on this page so that you will no longer see information about that node in the node alias selection on other tabs.

To access the GetStatus function in the chip-tool-web, first open the navigation bar and select GetStatus. The following interface will be displayed:

  • ${value}: The value of the attribute.

Additional Notes

  • Deleting the /tmp/chip_tool_config.ini file and any other .ini files in the /tmp directory may help to resolve problems caused by outdated configuration. Running rm -rf /tmp/chip_* will remove these files. This will allow the chip-tool-web to rebuild its configuration files from scratch.

  • The timeout for all buttons in the chip-tool-web that execute commands is set to 60 seconds. During the command execution process, the interface will display the command execution waiting effect. Please wait patiently for the command to finish executing and return a result of success or failed.

  • In general, commands related to Pairing may take longer to execute, while commands related to OnOff functionality will execute faster. If a pairing command takes a long time to execute and returns with failed, please check that the device configuration follows the documentation. Also, try pairing again after running rm -rf /tmp/chip_*.

  • The chip-tool-web supports commissioning multiple devices at the same time. However, in the current version, only one device can be connected at a time in each pairing mode. Therefore, the current version of chip-tool-web can pair and control three devices at the same time. Note that you should not run rm -rf /tmp/chip_* while commissioning multiple devices at once, as this will erase the useful information of the successfully paired devices.

  • New features are still being developed and expanded.
