Abstract

An embodiment of the invention provides a mobile terminal and a method for starting an OTG function of the mobile terminal. The method comprises the following steps: when the mobile terminal is placed in VR equipment, receiving first data transmitted from the VR equipment; when the first data are matched with preset second data, starting the OTG function of the mobile terminal. The problem that the OTG function of the mobile terminal in the prior art needs to be started normally is solved. The OTG function of the mobile terminal can be started as needed, and therefore, reliability and safety of a USB interface of the mobile terminal are improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method for enabling an OTG function of a mobile terminal and the mobile terminal. Background technique [0002] At present, the realization of the VR (Virtual Reality, virtual reality) function of smartphones is mainly based on the VR box, that is, the mobile phone is inserted into the VR box, and then image presentation and human-computer interaction are realized through the optical system and sensor unit in the VR box. The mobile phone and the VR box are connected through USB (Universal Serial Bus, Universal Serial Bus). Provide power for the VR box; on the other hand, the mobile phone also communicates with the VR box through OTG for data exchange. [0003] According to the USB OTG protocol, in order to realize the hot plug function of the OTG, the OTG must be kept in the normally open state, so the ID pin of the USB interface will always...
