A Mobile Learning System Based on Bluetooth

In order to improve learning flexibility and efficiency, and break the constraints of time and space, a mobile learning system based on Bluetooth was proposed and realized in the paper. The mobile learning system used Bluetooth technology as the communication media. To accommodate with the characteristic of portable devices, the system was designed for low power consumption and low learning cost. With the help of the system, a teacher can receive instant feedback from the students and check students´ performance at any time. The students can actively participate in the class and answer the teacher´s questions in an easier way. The system architecture, security issues, and key techniques on establishing the communication between cell phones and computers using Bluetooth on Java 2 platform were also explained in the paper.
