FMB920 device for unknown reasons suddenly stopped sending data to the server. I downloaded the log from FOTA and it says "Not enough records to send! Min: 1 Server: 0" I don't know why it sent data for a long time and suddenly stopped saving records. It is set to send every 4 minutes. It is outside and can see over 20 satellites. Below is an excerpt from the log:
