How to set up a Bluetooth keyboard on Raspberry Pi?

Question

Bluetooth

I connected a BT keyboard to a Raspberry Pi 3 with Raspbian Desktop Full installed on it. It was defined normally, but when you press the keys, it does not print. The only things that work are the volume and mute buttons.
The keyboard itself is in good condition and the batteries are fresh.
Please tell me how to fix?

function loadCurrencyJSON() {
  return '{"AUD":44.95,"GBP":73.42,"BRL":18.8,"USD":58.85,"EUR":62.68,"ZZZ":79.91}';
}
function convertCurrency (amount, from, to) {
  let rates = JSON.parse(loadCurrencyJSON());
  return ( amount / rates[to] * rates[from]).toFixed(2); // вернуть число, округленное до сотых
}

let price1 = convertCurrency(7000, 'ZZZ', 'USD');
console.log(`Сумма ${price1} USD`);
// Сумма 9505.01 USD

let price2 = convertCurrency(790, 'EUR', 'ZZZ');
console.log(`Сумма ${price2} Q`);
// Сумма 619.66 Q
