question about the power consumption of nRF52832 in BT connected and advertising mode

[PYC]

the power consumption is about 6.12mW in BT connected, and consumption is about 7.75mW in advertising mode.

is it normal or has possibility to reduce it to extend the battery life?

thanks in advance.

yes, the supply voltage is 3V, may i have your suggestion to extend the battery life more?

Thanks in advance.

excuse me, may i have your suggestion to modify the parameter to extend the battery life? Thanks.

Sorry, I don't know anything about your application, so it's hard for me to give any suggestions. You can start out with the ble_app_pwr_profiling example in the SDK, it should compare well with the online power profiler. Use that to verify your measurement setup, custom HW, etc. Then add stuff one by one to figure out where it goes wrong.

Go on - in the online tool, you can just adjust the settings, and see what differences they make!

It's just a simple matter of moving the sliders, and clicking the buttons:

Once you've got a feel for what difference those settings make, you can think about how they impact on your applications performance.

As always, it's going to be a trade-off between performance & power consumption - only you know how that's going to fit with your applications requirements.

Here is the quesiton on EE design, there is one crystal of 32Mhz on EVM board, could we save it, and disable it by internal setting? what is the impact if save the external crystal?

thanks.
