This is because once the counter stops or is reset, the difference between the value of the counter at the first timing and the value of the counter at the second timing, at which the log information is transmitted, does not match the period of time between the first timing and the second timing.
  • the inhaler device 100 has not been used for an extended period of time and the counter has stopped. After the non-use for the extended period of time, the inhaler device 100 is charged and activated again and, after the counter restarts, transmits log information stored before the non-use of the inhaler device 100. In this case, a difference between the value of the counter at the first timing, at which the log information was obtained, before the stop and the value of the counter at the second timing, at which the log information was transmitted, after the restart does not reflect the period of time for which the counter had remained stopped.
