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

How to Use Example

Before project configuration and build, be sure to set the correct chip target using:

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 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 for full steps to configure and use ESP-IDF to build projects.
