power modes for free-fall detection in BMA253

[Coleman]

Hello,

What is the most power efficient modes for detecting free-fall?

I actually ensured that I can detect free-fall in Normal Mode.

Total Supply Current in Normal Mode is 130uA.

So if I use CR2016 lithium battery (which is 90mAH), the battery life will be 90mAH / 130uA / 24 hours = 28.8 days.

I want to ask if there is more power efficient ways in detecting free-fall.

Thank you.

Hello Coleman,

To detect free-fall and save power consumption, you could use lower mode 2.

Thank you,

Now I am able to detect free-fall with Low-power Mode 2
