Thank you, Kenneth!

When I checked the value of dt, there was a problem that suddenly a very large value was printed out.
If the value of dt is higher than a certain number, I resolved it so that it would be the same as the previous value.

I suggest to print out t_now and t_prev, have in mind that app_timer_cnt_get() may be 0 and/or wrap around depending on whether there is any timers running or not. So you may need a check for if t_now is smaller than t_prev and/or if any is 0.

It doesn't seem as you have included the source of calcDT()?

Best regards,
