Abstract

La présente invention concerne un procédé de connexion de stylet et un système Bluetooth (BT). Au moyen d'une opération prédéfinie commode et rapide (telle qu'une opération de double clic, de triple clic ou d'appui long), un stylet peut être déclenché pour être appairé avec un dispositif électronique qui n'a pas été connecté auparavant, ce qui est simple, pratique et hautement adaptable. Le procédé comprend les étapes suivantes : un premier stylet émet une diffusion Bluetooth en réponse à la détection d'un événement cible, la diffusion Bluetooth transportant des premières informations d'indication et des secondes informations d'indication, les premières informations d'indication étant utilisées pour indiquer que le premier stylet peut être appairé, les secondes informations d'indication étant utilisées pour indiquer que le premier stylet peut être connecté, et l'événement cible comprenant un événement de double clic, un événement de triple clic, ou un événement d'appui long; en réponse à un balayage de la diffusion Bluetooth, un second dispositif électronique affiche une fenêtre d'invite de connexion, la fenêtre d'invite de connexion comprenant une première option utilisée pour ordonner au second dispositif électronique d'établir une connexion Bluetooth avec le premier stylet; et en réponse à une opération utilisateur sur la première option, le second dispositif électronique établit une connexion appairée avec le premier stylet.
