1. A communication method implemented by a first apparatus, the communication method comprising:
performing, when the first apparatus has not activated a host function and through a first transmission node that is coupled to the first apparatus and that is in a slave node mode, first data transmission, wherein the host function comprises a function of controlling a peripheral coupled to the first transmission node and controlling the first transmission node switched from the slave node mode to a master node mode, and wherein, while in the slave node mode, a first master node receives data collected by the peripheral through a transmission path between the first transmission node and the first master node;
performing one or more of detecting a signal for triggering a call, detecting interruption of the transmission path between the first transmission node and the first master node in a data communication system, or receiving, from the first transmission node, a first instruction instructing the first apparatus to activate the host function;
activating the host function responsive to detecting the signal, detecting the interruption, or receiving the first instruction;
sending, to the first transmission node, a second instruction instructing the first transmission node to switch from the slave node mode to the master node mode; and
sending, after the first transmission node has switched from the slave node mode to the master node mode, second data transmission with the first transmission node to receive the data collected by the peripheral.
