[Introduction]：Le module Bluetooth E104-BT40 est un module esclave Bluetooth série-bimode basé sur Bluetooth 4.2+3.0, prenant en charge le Bluetooth Low Energy (BLE) et le profil Bluetooth classique SPP. Il commute librement entre BLE et Bluetooth classique, fonctionnant sur la bande de fréquence 2,4 GHz. Les paramètres sont définis à l'aide de commandes AT courantes, ce qui simplifie et accélère l'utilisation.
