Abstract

A wireless communication device includes a main control chip and an outline interface. The main control chip includes a reset pin configured to reset the main control chip and a debug serial port input pin configured to read and detect a running state of a program. The debug serial port input pin is connected to a direct-current power source to receive a high voltage level input. The reset pin is disconnected from an input pin of the outline interface.
