# ESP-IDF BT/BLE HID Device Demo
|
|
|
|
This demo use APIs which esp_hid component provided to create a BT, BLE or Bluetooth dual mode hid device. Users can choose mode by setting `HID_DEV_MODE`.
|
|
|
|
|
|
This example works in companion with the [BLE HID Host Example](../esp_hid_host/README.md)
|
|
|
|
## 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>
|
|
```
|
|
The BT hid device plays as a mouse. When the connection is successfully established, users can follow the usage below to operate the 'mouse'.
|
|
|
|
```

|
BT hid mouse demo usage:
|
|
You can input these value to simulate mouse: 'q', 'w', 'e', 'a', 's', 'd', 'h'
|
|
q -- click the left key
|
|
w -- move up
|
|
e -- click the right key
|
|
a -- move left
|
|
s -- move down
|
|
d -- move right
|
|
h -- show the help
|
|

```
|
|
|
|
The BLE hid device plays as a remote control. When the connection is successfully established, the remote control will set volume up and down periodically.
|
|
This example implements a BLE HID device.
|
|
|
|
### Hardware Required
|
|
|
|
* A development board with ESP32 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
|
|
|
|
### 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](https://idf.espressif.com/) for full steps to configure and use ESP-IDF to build projects.
