COV stop after a while

[kazemiprince]

I am testing COV(for analog input object) with Yabe and I see COV stop sending new values to Yabe and have to subscribe again to see new values.
sometimes it stop after 1-2 minutes and sometimes it stop sooner.

Subscriptions have a "lifetime" parameter, Clause 13.14.1.1.4, what is the value from Yabe? Do the notifications stop for different versions of the parameter?

[kazemiprince]

its lifetime is 120 seconds.
notification stop randomly. I though it's because I run bacnet on another thread, but even if I run it on main , it stop again.
what I see is if I decrees the lifetime to 30 seconds, it will be much much better.

Checking the logs, it appears that self.algorithm.triggered = True is running late on line 55 of the service.Detect.py file. If we move that line to line 52, COV still appears to work.

Is this method correct?

Perhaps, that's not in the BACpypes code.
