## What it is
An Arduino-compatible C++ library that turns an ESP32 into a Bluetooth LE (BLE) keyboard. It lets sketches send keystrokes, text, individual key presses/releases, and media keys to paired host devices.

## Use cases
- make an ESP32 act as a bluetooth keyboard
- send keystrokes to a phone or computer from a microcontroller
- build a custom macro pad that types over bluetooth
- trigger media play/pause keys from an ESP32
- send text like 'Hello world' via BLE HID
- press key combinations like Ctrl+Alt+Delete remotely

## When to choose
- you want a cheap ESP32-based BLE HID keyboard for Arduino projects
- you need media key support that USB keyboard libraries lack
- you target Android, Windows, or Linux hosts

## When to avoid
- you need stable iOS or macOS support (known issues, especially with older devices)
- you need to read Numlock/Capslock/Scrolllock state (unsupported)
- you want a USB HID keyboard rather than Bluetooth LE

## Facets
- artifact type: library
- maturity: active
- function: embedded, sdk
- domain: embedded-systems, hardware, developer-tools
- platform: embedded, iot, cpp
- tags: esp32, bluetooth-le, ble-keyboard, arduino-library, hid, keystroke-injection
