W moim ostatnim projekcie potrzebuję komunikacji sprzętowej (Bluetooth Low energy). Mam wdrożony cały kod metod delegatów. Mogę podłączyć sprzęt i urządzenie, ale nie otrzymuję powiadomienia o parowaniu (załączony zrzut ekranu). Dlaczego nie prosi o parowanie? Dziękuję Ci.iOS Core Bluetooth Nie pyta o parę

Jeśli Rozumiem, że prawo można napisać wartości powodzeniem charakterystyczny ale nie dostaniesz prośbę parowania.

Parowanie jest wyzwalane przez urządzenie peryferyjne. Oznacza to, że urządzenie peryferyjne musi odrzucić prośbę o zapis lub odczyt centrali do charakterystyki. Twój punkt centralny otrzymuje odmowę "nieautoryzowanego uwierzytelnienia", a następnie próbuje sparować z urządzeniem peryferyjnym i pokazuje komunikat parowania, na który czekasz. Wszystko to odbywa się automatycznie przez rdzeń bluetooth. Jedyne, co musisz zrobić, to zmienić opcje charakterystyki i uprawnienia w swoim urządzeniu peryferyjnym. To jest przykładowy kod jabłoni wyzwolić parowanie:

emailCharacteristic = [[CBMutableCharacteristic alloc] 
    initWithType:emailCharacteristicUUID 
    properties:CBCharacteristicPropertyRead 
    | CBCharacteristicPropertyNotifyEncryptionRequired 
    value:nil permissions:CBAttributePermissionsReadEncryptionRequired];
