  • Case 413

    Question:
    Do a wireless devices always sync the time with every communication to the Gateway to ensure they're using the correct address time slot?

    Solution: Examples:
    Device 1 at address 1 transmit data at 10:00:01 > Success.
    Device 1 at address 1 transmit data at 10:01:02 > Clash with device 2 on address 2.
    Device 1 at address 1 transmit data at 10:02.02 + 50ms > Success and time sync by 1.5 seconds to the Rf module from the logger.

    Additional Information:
    Normal communication between a logger and gateway takes less than 200 milliseconds. There is normally enough time for a second logger with a wrong time to get also a time synch. But if both logger send the data at the same timeslot, a conflict can happen and there is no synchronisation.
