How to check one shot timer is running or stop?

[markevens]

I tried using "esp_timer_get_expiry_time" API, but it gives an error not declared in this scope. And trust me there is nothing problem with the code.

Anyone......

Hi, has there been any problem with the library installation? This error 'not declared in this scope' occurs when there is an unknown variable. Usually, when the included library is not installed but we try to compile a code, we often see this error.

Yes, I am using version 4.4 and that API is not in this version.
