nRF52 current consumption

[sfujimoto]

hello. Although example consumes less current when connected, in the project I made, consumption is not reduced even if it connects, what is the cause? The service seems to have completed communication normally. However, as far as the current consumption waveform is concerned, it seems that advertising is still continuing. Is there such a thing? Next I will attach the current waveform. It becomes 10 mA / 100 mV.

thanks.

You can try to adjust the two parameters above to 40ms. I think that should be enough for the amount of data you transmit.

There is a low power parameter for the ADC in the sdk_config.h file. Look for SAADC_CONFIG_LP_MODE.

As long as you call the power_manage() function in the main loop, the CPU should be sleeping between the events.

thanks, Although there is power_manage () in the main loop, we describe other processing, is it a rule violation?

No, you can do that, as long as you have control on how the application interrupts are handled and you know when power_manage() is returning to main loop. Or, you can use the app_timer library to set up a timed event, or use the scheduler to schedule application tasks.
