I’ve been working on a BLE-based door sensor project and my main focus has been on optimizing power consumption to maximize battery life. The device uses an nRF52840 chipset and the SDK version v2.4.1. I’ve been measuring the current consumption using the Power Profiler Kit 2, and it’s currently around 20mA, which is higher than I’d like.
I’ve included my prj.conf and overlay files for reference and would appreciate any suggestions or insights on how to achieve more efficient power management. I’ve tried disabling unused peripherals and adjusting the radio settings, but I’m still not seeing the improvements I was hoping for.
One thing I’m curious about is how others have managed to reduce power consumption in similar projects. Have you found specific configurations or libraries that make a significant difference? Any tips on balancing functionality with power efficiency would be greatly appreciated.
Looking forward to hearing your thoughts and experiences!
