Multi-part apparatus and data transmission method thereof

摘要

A multi-part apparatus and a data transmission method thereof are provided. The method is adapted to a multi-part apparatus having a master apparatus and a separable slave apparatus. The master apparatus and the slave apparatus are attached to each other through magnetism, and each of them has a wireless transmission module and a plurality of pins disposed on a side. In this method, a variation of the magnetism is detected, so as to determine a relative position between the master apparatus and the slave apparatus. When the master apparatus and the slave apparatus are attached to each other with a shift, a wireless connection set up by the wireless transmission modules is used for data transmission; and when the master apparatus and the slave apparatus are connected to each other with the sides thereof, both the wireless connection and the pins are used for data transmission.
