| # ESP-Hosted Instruction |
| |
| For SoCs that do not include a built-in Wi-Fi radio (such as the ESP32-P4), it |
| is still possible to run Matter-over-Wi-Fi by using the |
| [esp-hosted](https://github.com/espressif/esp-hosted) component together with a |
| slave Wi-Fi and Bluetooth co-processor. |
| |
| The following guide describes how to setup esp-hosted and configure the slave |
| co-processor for |
| [ESP32-P4 Function_EV_Board](https://docs.espressif.com/projects/esp-dev-kits/en/latest/esp32p4/esp32-p4-function-ev-board/index.html). |
| |
| ## Setup the slave co-processor |
| |
| Please refer to the |
| [Flash ESP32-C6](https://github.com/espressif/esp-hosted-mcu/blob/main/docs/esp32_p4_function_ev_board.md#5-flashing-esp32-c6) |
| section for detailed instructions on flashing the slave co-processor firmware to |
| the ESP32-C6 on the ESP32-P4 Function_EV_Board. |
| |
| ## Build Matter firmware for Host MCU |
| |
| The [all-clusters-app](../../../examples/all-clusters-app/esp32/README.md) |
| example can be used as the Matter firmware for ESP32-P4. After flashing the |
| slave co-processor, set the target, build and flash the firmware as shown below: |
| |
| ``` |
| idf.py set-target esp32p4 |
| idf.py build |
| idf.py -p <port> erase-flash flash monitor |
| ``` |
| |
| Once flashed, the device can be commissioned by a Matter commissioner. |
