Android-реализованный код подключения Bluetooth, но не работает на другом устройстве Android ⇐ Android

[Anonymous]

Я работаю над приложением Android, которое подключается к устройству Bluetooth с помощью BluetoothSocket. Однако, когда я пытаюсь подключиться, я получаю следующую ошибку:
работает, когда я пытаюсь подключиться к Bluetooth от ноутбука, но сбой, когда попробуйте подключиться с другим устройством Android (Redmi A2 (Androdi OS 13)) < /p >
