+# Bluetooth Examples for Bluedroid host
+
+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
+
+Demonstrates interaction with controller through HCI over UART.
+
+See the [README.md](./controller_hci_uart/README.md) file in the example [controller_hci_uart](./controller_hci_uart).
+
+## 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).
