I have an FMB900 - on Firmware 03.25.15.Rev.32 - the On Stop Settings are:
- Min Period = 3600
- Min Saved Records = 1
- Send Period = 120
Deep Sleep is enabled with a Timeout = 15 (mins).
The device appears to "wake up every hour" and send data to the server.
On the Server, I see the following:
- Satellites = 0
- GPS\GNSS Status = 3
- Altitude = 0
I get the impression that when the unit comes out of Deep Sleep to send the data packet as per Min Period (On Stop) of 3600s, the GPS isn't actually being used. Or by the time the GPS gets a fix (hot\warm start) the data packet has already been sent.
In System settings under Records Savings/Sending Without TS - the value is set to After Position Fix.
On Moving - I see values for Satellites, Altitude and GPS\GNSS Status = 1.
In I/O - GNS Status: Priority = Low and Operand = Monitoring.
Can anyone shed any light or explain how the On Stop works in terms of the GPS, i.e. does the unit wait up every Min Period, get a fix and then send the data packet? Or does it wake up and just send a data packet (without fix)? I am seeing the 2nd version (i.e. wake up & sends packet with no GPS fix).
I've gone through the logs on the server and the behaviour was there before as well.
