+# BLE Host-Only Peripheral VHCI Example
+
+This example uses the Bluetooth VHCI transport provided by ESP-Hosted.
+
+To use the VHCI transport in the application, the Bluetooth controller
+should be disabled and the default uart-transport should also be
+disabled (when the controller is disabled, by default the
+uart-transport is selected). The Bluetooth VHCI transport in
+ESP-Hosted should also be enabled.
+
+Refer to the `sdkconfig.defaults` file which has the required
+configuration.
+
+To test this demo, any BLE scanner app can be used.
+
+## How to Use This Example
+
+Before project configuration and build, be sure to set the correct
+chip target using:
+
+```bash
+idf.py set-target <chip_name>
+```
+
+### Configure the project
+
+Open the project configuration menu:
+
+```bash
+idf.py menuconfig
+```
+
+In the `Component config-> Bluetooth` menu:
+
+* Select `controller` to Disabled.
+* Disable `Nimble Options-> Host-controller Transport -> Enable Uart Transport`.
+
+In the `Component config-> ESP-Hosted config` menu:
+
+* Enable `Bluetooth Support-> Enable Hosted Bluetooth support`
+
+### Build and Flash
+
+Run `idf.py -p PORT flash monitor` to build, flash and monitor the
+project.
+
+(To exit the serial monitor, type ``Ctrl-]``.)
+
+See the [Getting Started Guide](https://idf.espressif.com/) for full
+steps to configure and use ESP-IDF to build projects.
+
+## Example Output
+
+This is the console output when `bleprph_host_only_vhci` is running on
+the ESP32-P4 and using the Bluetooth Controller of the ESP32C6 on the
+ESP32-P4-Function-EV-Board. The data is transferred through SDIO
+between the ESP32-P4 and ESP32-C6:
