ESP32 Hosted Configuration

ESP32 Hosted ESP32-C6 coprocessor configuration:

esp32_hosted:
  active_high: true
  variant: ESP32C6
  reset_pin: GPIO54
  cmd_pin: GPIO19
  clk_pin: GPIO18
  d0_pin: GPIO14
  d1_pin: GPIO15
  d2_pin: GPIO16
  d3_pin: GPIO17

Wi-Fi Configuration

The ESP32-C6 coprocessor enables Wi-Fi functionality:

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

Bluetooth Proxy Configuration

The ESP32-C6 coprocessor enables Bluetooth proxy functionality - could require a C6 firmware update to work:

esp32_ble_tracker:
  scan_parameters:
    interval: 1100ms
    window: 1100ms
    active: true


bluetooth_proxy:
  active: true
  connection_slots: 3

Ethernet Configuration

Configuration to use the onboard 100M Ethernet with IP101 PHY:

ethernet:
  type: IP101
  mdc_pin: GPIO31
  mdio_pin: GPIO52
  power_pin: GPIO51
  clk:
    mode: CLK_EXT_IN
    pin: GPIO50
  phy_addr: 1

Coprocessor Firmware Update

The ESP32-C6 coprocessor firmware can be updated over-the-air using the esp32_hosted update platform:
(see esp32_hosted component)

update:
  - platform: esp32_hosted
    name: "C6 Coprocessor Update"
    path: /path/to/network_adapter.bin
    sha256: your_sha256_hash_here

The firmware binary is embedded into the ESP32-P4’s flash at compile time and can be deployed to the coprocessor on demand. The component automatically detects the current firmware version and compares it to the embedded version. If they differ, an update becomes available in Home Assistant.
