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
