+ESP-IDF UART HCI Controller
+===========================
+
+This is a BLE controller use UART as HCI interface. 
+
+It can do the configuration of UART number and UART baudrate by menuconfig.
+
+## BLE HCI example
+
+(See the README.md file in the upper level 'examples' directory for more information about examples.)
+
+This example start controller with uart hci.
+
+It uses ESP32C2's Bluetooth controller.
+
+In this example, two UARTs are used:
+
+- UART0 is used as normal output or by IDF monitor
+
+- UART1 is used to convey HCI messages
+
+Pins 8, 9 are used as TxD, RxD PINs of UART1.
+
+
+## How to use example
+
+### Configure the project
+
+```
+idf.py menuconfig
+```
+
+
+### Build and Flash
+
+Build the project and flash it to the board, then run monitor tool to view serial output:
+
+```
+idf.py -p PORT flash monitor
+```
+
+(To exit the serial monitor, type ``Ctrl-]``.)
+
+See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
+
+## Example Output
+
+There is this console output when bleprph is connected and characteristic is read:
+
+```
+set nimble port tx:8, rx:9.
+set baud:115200.
+controller lib commit: [fb738d4]
+controller rom commit: [3314f9d]
+I (346) system_api: Base MAC address is not set
+I (356) system_api: read default base MAC address from EFUSE
+
+```
