A wireless communication method capable of preventing communication interference and cut-off in one-to-multi wireless communication. The wireless communication method has the steps of: determining as to whether communication parameters satisfy a precondition for communication before a master device communicates with a slave device in a corresponding mode, the communication parameters being required for the slave devices to communicate with the master device, the precondition being that the slave devices should communicate with the master device without overlapping of communication time thereof; controlling the communication of the slave devices according to the corresponding mode by differently setting operation information of the slave devices according to the corresponding mode, when determining that the communication parameters satisfy the precondition for communication; and maintaining a connection between the slave device and the master device until the communication completes, when the time of operation of the slave devices ends due to the corresponding mode shift when the communication is not completed between the master device and the slave device. Accordingly, the interference and cut-off of communication with the slave devices of different communication times and cycles in corresponding mode can be prevented.
