Kurulum

Yakındaki Bağlantılar özelliğinin nasıl kurulacağıyla ilgili bilgi edinmek için lütfen Yakındaki Bağlantılar konusuna bakın.

Kısa Mesajlar

Yakındaki Bağlantılar, istemcilerinin uzak cihazla bağlantı kurmadan 131 bayt içinde veri göndermesine olanak tanır. 131 bayt içindeki iletilerin nasıl aktarılacağını öğrenmek için lütfen aşağıdaki akışa bakın.
