The invention provides a communication method and device. The method comprises the following steps: determining a first target communication interface which receives a first external command among a plurality of communication interfaces arranged according to a preset arrangement order; if there is a second target communication interface in a locked state in the plurality of communication interfaces, keeping the communication device connected with the first target communication interface; sending a preset command indicating the presence of the locked communication interface to the first targetcommunication interface in response to the first external command; if it is detected that the state of the second target communication interface is switched to the unlocked state, starting from the first communication interface arranged after the last responded communication interface, circularly polling whether the plurality of communication interfaces receive external commands according to a preset arrangement order until polling the third target communication interface which receives the external commands; processing the external instructions of the third target communication interface. Thecommunication device of the invention can simultaneously connect a plurality of communication interfaces to carry out communication when communicating with a host computer.
Description
technical field [0001] The present invention relates to the technical field of mobile Internet, in particular to a communication method and device. Background technique [0002] At present, with the rapid development of the mobile Internet, there are more and more types of transactions on mobile terminals. In order to ensure the security of mobile transactions, many key products have been derived, such as USBkey, Bluetooth Key, audio Key and so on. [0003] Among them, compared with the USB key, the Bluetooth Key and the Audio Key not only support the communication connection with the host computer through USB, but also support the communication connection with the host computer in the way of Bluetooth and audio. The so-called upper computer refers to the electronic equipment using the key product, such as mobile terminals (including but not limited to mobile phones, tablet computers) and terminals (including but not limited to personal computers (PC, personal computer)). ...
