Получить данные с устройства Bluetooth с Android Studio

Question

Я использую модуль Bluetooth HC05 в Arduino, и я пытаюсь получить данные на последовательном мониторе и отобразить их в приложении для Android, но он не работает. Есть две основные кнопки: первая для отображения данных из HC05, вторая для отправки данных на последовательный монитор. Я поместил свой адрес андроида в переменную, чтобы установить связь, но в приложении ничего не отображалось, это код ниже:
