So to use app_timer_freertos.c what should I do? I have already disabled APP_TIMER but getting the following errors:

So please tell me how to use app_timer_freertos.c in this situation. And also how to solve nrfx_timer error.

Hello,

I like to change the direction. Because, It looks possible to archive sleep mode without disable softdevice.

But, I met another issue. So I will start conversation in other thread.

Thanks for support.

Yes, I use app_timer_freertos.c

Is there any reference to enable and disable softdevice when FreeRTOS is used?

Or Could you tell me proper way to enable and disable softdevice with FreeRTOS?

Thanks,

Chongchun Moon

Hi Moon,

you should not use app_timer.c when using freertos. Instead you should use app_timer_freertos.c (the header file is the same for both, app_timer.h)

app_timer_freertos.c does not use RTC, but instead uses the internal timer features of the RTOS itself. So you have no problem using that.
