Abstract: A Bluetooth v4.0-based intelligent electronic cigarette is provided with a casing including an atomizer, a controller, and a battery. The controller includes a software and hardware assembly having an MCU, and a Bluetooth-based board having a Bluetooth v4.0 module connected to the MCU, the Bluetooth v4.0 module being capable of transmitting data processed by the MCU, and receiving data and transmitting same to the MCU. The battery is electrically connected to the MCU. The Bluetooth v4.0 module is employed to implement a two-direction communication between the electronic cigarette and a mobile app, thereby enabling a user to control his/her simulated tobacco smoking by monitoring what is shown on the mobile app.
