FreeRTOS + sd_app_evt_wait (Sleep as much as possible)

[Jur]

I would like to make the nRF sleep as much as possible.
In the FreeRTOS application idle hook I first process any scheduled events ( app_sched_execute() ), i can confirm this works as the scheduled events are processed.
After this I call sd_app_evt_wait(), to make the nRF sleep, yet there is no change in power consumption.

So I am wondering:

• is the FreeRTOS idle hook the right place to call sd_app_evt_wait() ?
• would sd_app_evt_wait() make the nRF sleep even when FreeRTOS is used?

Could someone explain how to make the nRF sleep as much as possible when using FreeRTOS?

Thanks a lot!

Hi

What SDK version are you using? Please check out this blog post by my colleague Jimmy, where he explains how to optimize current consumption with FreeRTOS in the nRF5SDK.
