sd_app_evt_wait uses app timer

[annapalu]

Hi all,

Con i use the function sd_app_evt_wait without use the library app_timer? Thanks, Anna

There should be no link between library like app_timer and any SD API function call like this one. How you came to this?

Hi endode,

i am using a sd_app_wait to go in sleep mode. I have chenage the library and don t use the app timer, but i have created another library to create a SW timer.

I use the same pheriphera RTC1, but when i call the sd_app_wait the cosnumption is higher(now is 100 uA than before when i used the app timer library)

OK, so the problem is power consumption? And you think that it's because of RTC1? No other change? If you would say on which chip you do this (and which SD version and SDK you use etc.) then we might have a look if it makes sense according to electrical characteristics of the chip on Infocenter but it can very well be correct. If you think that previous implementation of timer worked better then I suggest to go back to it.
