ISO/IEC 15961-4:2016 provides a set of application commands and their associated responses for the following functions: - to start and stop battery assistance; - to select and de-select a particular sensory function supported by the RFID tag; - to set sensor parameters both initially and ongoing; - to start and stop the sensor monitoring the environment; - to access sensor data; - to establish the battery status. ISO/IEC 24753 defines the encoding rules for identifying sensors, their functions, their delivered measurements, and the processing rules for sensor data. As such, it receives commands as defined in ISO/IEC 15961-4:2016 and provides the information that is required for the appropriate responses.
