Tôi đang chạy mẫu Trò chuyện Bluetooth từ gói mẫu Android SDK 4.2 mà không sửa đổi mã. Mục tiêu của tôi là Nexus 7 chạy Android 4.2.2. Tôi nhận được các lỗi này ngay khi tôi thử kết nối an toàn với thiết bị được ghép nối. Kết nối không an toàn cũng không thành công, dẫn đến lỗi tương tự. Thỉnh thoảng, sau khi tôi khởi động lại BT, kết nối sẽ thành công.Bluetooth Secureaccept() Không thành công, Nexus 7, Android 4.2.2
Tôi đã nghiên cứu điều này và thấy rất nhiều tài liệu tham khảo cho các sản phẩm BT trên Android 4, nhưng tôi nghĩ rằng chúng được cho là đã được sửa trong phiên bản 4.2 tiếp theo. Nexus 7 là thiết bị duy nhất của tôi nên tôi tự hỏi liệu điều này có xảy ra trên các thiết bị khác hay không.
Có cách giải quyết nào cho sự cố này không? Cảm ơn trước cho bất kỳ hướng dẫn!
CẬP NHẬT: Sau khi điều tra thêm, tôi tìm thấy this link, cho biết có sự rò rỉ trong ngăn xếp tài nguyên BT, vẫn còn trong 4.2.2, có thể được giải quyết bằng cách dừng/khởi động lại thủ công BT. Có ai tìm thấy cách giải quyết có lập trình không?
