Abstract

One embodiment of the invention provides a method for starting the OTG function of a mobile terminal and a mobile terminal. The mobile terminal is configured with a first Hall switch. The method comprises following steps: when the mobile terminal is put in a virtual reality VR device, the mobile terminal receives a first interruption signal generated by the first Hall switch and the VR device is configured with a second Hall switch; for the first interruption signal, the mobile terminal starts the OTG function; when a second interruption signal generated by the second Hall switch is received within a preset period of time, the OTG function is kept on. Thereby the problem that the OTG function of the mobile terminals in the prior art needs to keep the normally start state is solved so that the mobile terminal can turn on the OTG function on demand; the reliability and safety of USB interface of mobile terminals is increased.

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...
