Possible cause:
In case of a large amount of stored data, the device cannot transmit all the data in one transmission session. The data transmission priority is GNSS data > Environment Data > ODBA. So that’s why you may see complete GNSS data while the latest ENV Data and ODBA is “lost”.
Solution: You don't need to take any actions. The rest data will be transmitted in the following transmission sessions until all the data is transmitted.
