Yes, it is done using the measurement data retention system.
By default, measurements data are an average of 5 minutes interval and are sent to servers every 5 minutes. Whenever a problem occurs during data transmission and the sensor will not receive a confirmation message from the server, data will be stored in a memory queue for the next transmission window. The queue can store up to 24 measurements in case of a GSM communication failure (cellular network failure, etc.). At 5 minutes transmission interval it converts into 2 hours of data retention.
If a transmission problem lasts longer than 2 hours, data samples stored in the queue will be overwritten based on oldest timestamp hierarchy. Measurement retention mechanism works automatically and does not need user action to work properly.
