Trong dự án gần đây của tôi, tôi cần giao tiếp phần cứng (Bluetooth Low energy) .Tôi đã triển khai tất cả mã phương thức đại biểu. Tôi có thể Kết nối phần cứng và thiết bị, Nhưng tôi không nhận được cảnh báo ghép nối (Ảnh chụp màn hình được đính kèm). Tại sao nó không yêu cầu ghép nối? Cảm ơn bạn.iOS Core Bluetooth Không yêu cầu cặp
