# BLE HTP 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 Health Thermometer service (0x1809) as primary service UUID.
|
||||
|
||||
After connection it enables bonding and link encryprion if the `Enable Link Encryption` flag is set in the example config.
|
||||
|
||||
It performs four GATT operations against the specified peer:
|
||||
|
||||
* Reads the HTP temperature type characteristic.
|
||||
|
||||
* After the read operation is completed, writes the HTP measurement interval characteristic.
|
||||
|
||||
* After the write operation is completed, subscribes to indications for the HTP temperature measurement characteristic.
|
||||
|
||||
* After the subscribe operation is completed, it subscribes to notifications for the HTP intermediate temperature characteristic.
|
||||
|
||||
If the peer does not support a required service, characteristic, or descriptor, then the peer lied when it claimed support for the Health Thermometer 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 Health Thermometer service (0x1809) 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 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.
|
||||

||||

# BLE Heart Rate Measurement Example
|
||||
|
||||
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
||||
|
||||
This example creates GATT server demonstrating standard Health Thermometer profile. It simulates temperature measurement and notifies to client when the notifications are enabled.
|
||||
|
||||
It advertises support for the Health Thermometer service (0x1809) as primary service UUID.
|
||||
|
||||
When internmediate temperature characteristic is subscribed, the timer resets and it sends notifications to client every 1 sec.
|
||||
|
||||
It uses ESP32's Bluetooth controller and NimBLE stack based BLE host
|
||||
|
||||
This example aims at understanding notification subscriptions and sending notifications.
|
||||
|
||||
## 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
|
||||
|
||||
