KW45 custom board is consuming more power.

[Lichade]

KW45 custom board is consuming more power. I am using SDK wireless example code as base for my application, so can you please guide me , what are all the steps i should follow to reduce power consumption(how can i optimize my code for lower power consumption , any RTOS specific things , low power APIs, any sdk managment related, etc whatever i can do ) , i am sharing screenshot ,so please analyze it and let me know what can be the possible causes for such current consumption behavior. i will appreciate if i get answer as soon as possible , as i am stuck .

Hello

Could you help us confirm what Low power SDK Wireless example code are you using as base for your custom code and from which SDK version?

I would recommend this Information in SDK Documentation LowPower — MCUXpresso SDK Documentation, this information describes the connectivity software architecture and provides the general low power enablement user guide, also contains examples codes or API descriptions that can help you on your Low power application.

Chapter 2 Low power Application user guide, this section provides a user guide to enable Low power on a connectivity application using KW45B41Z-EVK files as example.

On this other link Low-Power Management — MCUXpresso SDK Documentation you can find complementary information about "When/how to enter low power".

There is an application note that provides information about power consumption analysis for KW45 Kinetis KW45 and K32W1 Bluetooth LE Power Consumption Analysis, on this guide you can see how current consumption operates in Low power modes including timing and current values.

Also, as you are using a KW45 Custom board, kindly verify you are following the recommendations on The best way to build a PCB first time right with KW45 (Automotive) or K32W1/MCXW71 (IoT/Industrial)... and KW45 Hardware Design Recommendations for your board design.

Best Regards
