In today's digital era, the combination of digital technology and education to promote education has become a trend. One example is the pen control system. In the current mainstream pen control system, the communications between the smart pen and the smart terminal device like a tablet computer all use Bluetooth technology. This paper designs the self-adaptive identification and pairing scheme between the Bluetooth pen and the smart tablet by analyzing the Bluetooth protocol structure. This paper implements the application software of the Bluetooth master based on the Android tablet, which illustrates the feasibility of the scheme.
