Building the Example Application

Building the example application is quite straightforward.

gn

cd examples/chip-tool
git submodule update --init
source third_party/connectedhomeip/scripts/activate.sh
gn gen out/debug
ninja -C out/debug

• After the application is built, it can be found in the build directory as out/debug/chip-tool

Using the Client to Pair a device

In order to send commands to a device, it must be paired with the client.

Pair a device

To initiate a client pairing request to a device, run the built executable and choose the pairing mode.

Pair a device configured to bypass Rendezvous

The command below pair a device with the provided IP address and port of the server to talk to.

$ chip-tool pairing bypass 192.168.0.30 5540

Pair a device over BLE

Run the built executable and pass it the discriminator and pairing code of the remote device.

The command below uses the default values hard-coded into the debug versions of the ESP32 all-clusters-app:

$ chip-tool pairing ble 20202021 3840

Unpair a device

$ chip-tool pairing unpair

Using the Client to Send CHIP Commands

To use the Client to send a CHIP commands, run the built executable and pass it the target cluster name, the target command name as well as an endpoint id.

The endpoint id must be between 1 and 240.

$ chip-tool onoff on 1

The client will send a single command packet and then exit.

How to get the list of supported clusters

To get the list of supported clusters, run the built executable without any arguments.

$ chip-tool

Example output:

Usage:
  ./chip-tool cluster_name command_name [param1 param2 ...]
