the defusable clock was working fine many time, but now, i have a problem, i can now only change the countdown timer by pressing the “alarm” button and, when i set the countdown, when it reach 0:00 it make nothing and continue coutndown with 10:00 minutes, i have tried to resend firmware (i have the cable and the firmware V2.0 ) and after that, set countdown have the same problem (can only set countdown by pressing alarm button) and after reach 0:00 in countdown it continue countdown with 10 minutes, it never stopping the countdown (exept if i cut the good cable or if i cut wrong cable (detonate)
it is normal or i am dumb and its a part of the new firmware programation to “Loop” the countdown ?
i read is a simila problem as this post: viewtopic.php?f=34&t=2914
But mine loop the countdown when reach 0:00 (make infinity countdown)
EDIT: i have checked (visual) the circuit and i doesnt find any problems, scratch or bad connection.
