SDK V12.2 Power Saving Mode Issue

[Kevin Zhang@PRECINTL]

We have written code based on SDK V12.2 and found it doesn't support power saving mode. Given that it's very complicated to transplant to higher version, how can we fix the issue just on V 12.2?

BTW, I saw the same issue was discussed around 2 years ago, but it seemed the solution given didn't work at all, the questioner found some other way to fix it by himself. But I failed to find the questioner.

Thank you in advance!

Best regards!

Kevin, could you explain the problem you're facing? What function is not supported?

I might be having a similar issue:

Hi, what do you mean by "power saving mode"?

Hi Pimvds!

Thanks for your help in the first place!

The problem is that it seems that V12.2 doesn't support "go sleep"? Or we can't get into power saving mode, and our battery drained out in just one day. Here is a similar question on this:

https://devzone.nordicsemi.com/f/nordic-q-a/21219/freertos-high-power-consumption-in-sdk-12-2.

But it seems you don't have issue while using 12.2? Or you fixed the issue?

Please let me know!

Many thanks!

Hi Stian!

It seems there is an intrinsic issue with SDK V12.2 that you can't go to "Go Sleep" mode as it supposed be.

This question was asked around 2 years ago but we didn't get a clue from the discussion and still don't how to fix it.

Hi Kevin,

You are right that this is an issue with the FreeRTOS port in SDK 12. This is fixed in SDK 13, so you can either migrate to it or use just the FreeRTOS implementation from SDK 13, as suggested in this post.
