A METHOD OF OPERATING A WIRELESS LOGGER DEVICE

This invention relates to a method of operating a wireless logger device at least prior to placing the logger device in a transport mode where the logger device is configured to monitor an environmental related parameter of an asset while the asset is transported from an origin location to a destination location. The method includes setting the logger device in a first low-power mode where the environmental related parameter is measured by the sensing device and where the resulting environmental related data is stored in the storage medium, where in the low-power mode the logger device communicates with an external data processing device with at least one first-time frequency where the logger device is temporarily set to a first higher-energy mode during the communication with the external data processing device. The invention further includes identifying if there is a deviation in the measured environmental related data, where in case a detected deviation exceeds a pre-defined deviation target, adjusting the logger device to a second higher energy mode and: checking if the logger device is to be set to a transport mode, where in case the checking results in that the logger device is to be set to a transport mode, adjusting the communication frequency with the external data processing device to a second-time frequency, the second-timer frequency being larger than the first-time frequency, where in case the checking results in that the logger device is not to be set to a transport mode, adjusting the logger device to a second low-power mode and adjusting the communication frequency with the external data processing device to at least one third-time frequency, at least one third-time frequency being lower than the second-time frequency
