[Tushar_V]

Hi all,

i'am using nrf_Connect_sdk when i write this api 

device_set_power_state(); it gives me undefined symbol

i enable CONFIG_TICKLESS_IDLE=y in prj.conf it gives me undefined symbol  TICKLESS_IDLE

which file i should include or enable flags so the above api works

Regards

Hello, 

What version of the nRF Connect SDK are you working on? Are you running custom FW or a sample from the SDK?

Kind regards,

I am not able to find any KConfig option called CONFIG_TICKLESS_IDLE

Please note that device_set_power_state(); has been renamed in Zephyr v2.6.0. See release notes

The device power management (PM) APIs and data structures have been renamed from device_pm_* to pm_device_* since they are not device APIs but PM subsystem APIs. The same applies to enumerations and definitions, they now follow the PM_DEVICE_* convention. Some other API calls such as device_set_power_state and device_get_power_state have been renamed to pm_device_state_set and pm_device_state_get in order to align with the naming of other device PM APIs.

You can find more information about the Power Management API here. This page also includes some samples on use.

Kind regards,
Øyvind
