# BLE CTS Cent Example
(See the README.md file in the upper level 'examples' directory for more information about examples.)
This example creates GATT client and performs passive scan, it then connects to peripheral device if the device advertises connectability and the device advertises support for the Current Time Service (0x1805) as primary service UUID.
It performs following GATT operations against the specified peer:
* Reads the Current Time characteristic.
If the peer does not support a required service, characteristic, or descriptor, then the peer lied when it claimed support for the Current Time Service! When this happens, or if a GATT procedure fails, this function immediately terminates the connection.
It uses ESP32's Bluetooth controller and NimBLE stack based BLE host.
This example aims at understanding BLE service discovery, connection, encryption and characteristic operations.
To test this demo, use any BLE GATT server app that advertises support for the Current Time Service (0x1805) and includes it in the GATT database.
## How to Use Example
Before project configuration and build, be sure to set the correct chip target using:
```bash
idf.py set-target <chip_name>
```
### Hardware Required
* A development board with ESP32/ESP32-C2/ESP32-C3/ESP32-S3/ESP32-H2/ESP32-C6 SoC (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.)
* A USB cable for Power supply and programming
See [Development Boards](https://www.espressif.com/en/products/devkits) for more information about it.
### Configure the Project
Open the project configuration menu:
```bash
idf.py menuconfig
```
In the `Example Configuration` menu:
* Change the `Peer Address` option if needed.
### 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 on successful connection:

# BLE Current Time Service Example
(See the README.md file in the upper level 'examples' directory for more information about examples.)
This example creates GATT server demonstrating standard Current Time Service.
It advertises support for the Current Time Service(0x1805) as primary service UUID.
It uses ESP32's Bluetooth controller and NimBLE stack based BLE host
## How to Use Example
Before project configuration and build, be sure to set the correct chip target using:
```bash
idf.py set-target <chip_name>
```
### Hardware Required
* A development board with ESP32/ESP32-C3 SoC (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.)
* A USB cable for Power supply and programming
See [Development Boards](https://www.espressif.com/en/products/devkits) for more information about it.
### 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 console output can be observed when client is connected to server :
