# Bluetooth Examples for Host Controller Interface Note: To use examples in this directory, you need to have Bluetooth enabled in configuration. # Example Layout This directory includes examples to demonstrate controller interactions by virtual HCI layer and UART. ## controller_hci_uart_esp32 Demonstrates interaction with controller through HCI over UART. See the [README.md](./controller_hci_uart_esp32/README.md) file in the example [controller_hci_uart_esp32](./controller_hci_uart_esp32). ## controller_hci_uart_esp32c3 Demonstrates interaction with controller through HCI over UART on ESP32-C3. See the [README.md](./controller_hci_uart_esp32c3/README.md) file in the example [controller_hci_uart_esp32c3](./controller_hci_uart_esp32c3). ## controller_vhci_ble_adv Demonstrates interaction with controller though virtual HCI layer. In this example, simple BLE advertising is done. See the [README.md](./controller_vhci_ble_adv/README.md) file in the example [controller_vhci_ble_adv](./controller_vhci_ble_adv). ## ble_adv_scan_combined Demonstrates interaction with controller. In this example, BLE advertising and scanning is done. Also scanned advertising reports are parsed and displayed. See the [README.md](./ble_adv_scan_combined/README.md) file in the example [ble_adv_scan_combined](./ble_adv_scan_combined). ## hci_common_component This is separate component adding functionalities for HCI Layer. Since this component is just used by HCI examples, it is not placed in global components.
