      There's NO hysteresis in SmartBeaconing. Hysteresis again has an
      overlap area where you can be in either state when between the two
      limits depending upon from beyond which value you approach. There's no
      possibility of that in SmartBeaconing.

      You will get totally predictable results if you set your low speed to
      5 and high speed to 6 with SmartBeaconing.

      Any official answer on this? My OT2 is going to profile2 again (speed 5) altough the vehicle is stopped and the position reported is not moving at all:

        How can I fix that? Does anybody have the same problem, or
        is my OT2 faulty?

          Is vertical movement included in the speed calculations? I am thinking that a vertical change counts towards speed in the GPS too. Best regards, Fred _____

              My OT2 goes sometimes into high speed profile when the car
              is stopped and GPS removed or powered off. The altitude should
              not change in this case. Sending it commands over the air to
              switch back to profile 1 is not effective, it returns to profile 2
              almost immediately. This is very hard to reproduce, but happens
              every couple of weeks or so. Sending a RESET doesn't help either.
              I have "Save last fix" on in both profiles. Since the problem
              shows up even after a reset, I would assume there is a bug with
              the "save last fix" thing. Maybe it goes to some weird value
              like MAXINT or -1 or something in special circumstances, and makes the
              OT2 speed calculations go crazy.

              Thanks,

                It still sounds like its being switched back by the settings of your profile switching setup. I've noticed if the conditions are such to be in profile "1" no matter how many commands you send for Profile "2" it will always switch immediately back to profile "1".
                If its possible can you post a dump or post your .cfg file in the files section? It would help to see what all your settings are.
