Thread Border Router

This example creates a Matter Thread Border Router device using the ESP Matter data model.

See the docs for more information about building and flashing the firmware.

1. Additional Environment Setup

1.1 Hardware Platform

The ESP Thread Border Router board which provides an integrated module of an ESP32-S3 and an ESP32-H2 is required for this example.

1.2 Firmware for RCP

The OpenThread RCP should be run on ESP32-H2 of the Border Router board. You can flash it directly:

$ cd /path/to/esp-idf/examples/openthread/ot_rcp
$ idf.py set-target esp32h2 build
$ idf.py -p <port> erase-flash flash

Or you can flash the firmware of ESP32-H2 with esp_rcp_update after enabling AUTO_UPDATE_RCP in menuconfig:

$ cd /path/to/esp-idf/examples/openthread/ot_rcp
$ idf.py set-target esp32h2 build

After flashing the Thread Border Router firmware to ESP32-S3, it will flash the RCP firmware to ESP32-H2 automatically.

1.3 Firmware for Host SoC

The default setting flash size is 8MB, set target and build as below:

$ idf.py set-target esp32s3
$ idf.py build

2. Post Commissioning Setup

After commissioning the Border Router with chip-tool, you can set up the Thread network with ThreadBorderRouterManagement cluster.

$ ./chip-tool generalcommissioning arm-fail-safe 180 1 0x7283 0
$ ./chip-tool threadborderroutermanagement set-active-dataset-request hex:<thread-dataset-tlvs> 0x7283 1
$ ./chip-tool generalcommissioning commissioning-complete 0x7283 0

Then the Thread Border Router will form/join a Thread network and you can commission a Thread End-device to the Thread network with chip-tool.

$ ./chip-tool pairing ble-thread 0x7384 hex:<thread-dataset-tlvs> 20202021 3840
