SpaceLynk lost data from trend logs when have the power interrupted

Hi!

SpaceLynk

Then, when the power supply to the SpaceLynk module is interrupted, it loses all stored data in trend logs starting at 00:00 of the current day until the voltage is restored.

Question: is the data from 00:00 saved in the operative memory and only after a 24-hour cycle written in the independent memory? What is the reason for data loss?

To protect the SD card from extensive usage (and get corrupted in the end) the controller saves al configuration on a 15 minute interval (i thought 30 minutes but manual states 15), but the trend saving is based on the total trend size, how bigger the total trend size is set how longer the save interval is, so yes what you notice is correct and is functioning as designed.

This is from the release notes 2.1.1:

If you want to prevent this from happening than you should use a form of UPS to avoid you controller to restart by power failure, a manual restart from the OS will save everything first.
