Should I check the app timer state before restop or restart it?

[cgha]

Is it acceptable if I stop an app timer for dozens of times when the app timer is actually stopped. Will the memory leak if I operates in these scenario.Does it affect whether use scheduler when I init the app timer?

Hi

I think the safer approach would be to maintain a state variable in your code, that you check before starting or stopping the timer. I quickly do not see the state checked internally.

I have not confirmed it but I think it would be the safest way to maintain a state variable that registers if a certain app-timer is started or stopped.

• Whenever you start a timer, you register in the state variable that it is started.
• If you stop a timer, then you register in the state variable that it is stopped.
• You only start an app-timer if the state variable indicates that the app-timer is stopped.
• You only stop an app-timer if the state variable indicates that the app-timer is started.

Try it to see if the behavior improves.
