APP_ADV_INTERVAL and APP_ADV_DURATION

[kathleenlai]

Hi, 

I'm trying to look for a definition for the APP_ADV_DURATION and APP_ADV_INTERVAL. 

#define APP_ADV_INTERVAL                300                                    /**< The advertising interval (in units of 0.625 ms. This value corresponds to 187.5 ms). 
#define APP_ADV_DURATION                18000                                  /**< The advertising duration (180 seconds) in units of 10 milliseconds. 

How does we know the value we set is in units of 0.625ms or 10ms ?

Can anyone teach me? or guide me any module shall I look into?

Hi Simonr, thank you so much, you are so helpful.

Hi Simonr, by the way, where can I get the concatenate function declaration  for the specific word "interval " and "duration" since APP_ADV_INTERVAL and DURATION are not possible to edit though and have these units for a reason.
