Method and apparatus for controlling information acquisition between master-slave devices

摘要

A method and apparatus for controlling acquisition of information between a master-slave device are provided. In the method, the master device requests sensor information from the first slave device, receives sensor information according to the request from the first slave device, and obtains a response time at which the sensor information is received. Further, the master device calculates a difference between a response time when sensor information is received from the first slave device and a response time when sensor information is received from a second slave device, and information on the first slave device based on the difference. Update the request cycle.
