ESP32 as Bluetooth Keyboard

With its built-in Bluetooth capabilities, the ESP32 can act as a Bluetooth keyboard. The below code is a minimal example of how to achieve it. It will generate the key strokes for a message whenever a button attached to the ESP32 is pressed.

For the example setup, a momentary button should be connected to pin 2 and to ground. Pin 2 will be configured as an input with pull-up.

In order to receive the message, add the ESP32 as a Bluetooth keyboard of your computer or mobile phone:

Go to your computers/phones settings
Ensure Bluetooth is turned on

	v=v.replace(/\D/g,"") //Remove tudo o que não é dígito
	v=v.replace(/^(\d{2})(\d)/,"$1.$2") //Coloca ponto entre o segundo e o terceiro dígitos
	v=v.replace(/^(\d{2})\.(\d{3})(\d)/,"$1.$2.$3") //Coloca ponto entre o quinto e o sexto dígitos
	v=v.replace(/\.(\d{3})(\d)/,".$1/$2") //Coloca uma barra entre o oitavo e o nono dígitos
	v=v.replace(/(\d{4})(\d)/,"$1-$2") //Coloca um hífen depois do bloco de quatro dígitos
	return v
	}
