I want to receive data after a while that the system is put in its position and the battery life is very important to me. so I want to ask, can I start the chip and put it in system on mode, but all the peripherals except one RTC or timer be off and disabled and after a time that being set by RTC or timer, the Radio transceiver start working and sending data?[/quote] <p>Yes, this is the common way most BLE chips work.</p> [quote userid="91869" url="~/f/nordic-q-a/64422/using-rtc-to-wake-up-the-radio-transceiver-of-the-nrf52832"]how much is the current consumption in waiting mode?[/quote] <p>according to&nbsp;<a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/pmu.html?cp=4_2_0_16_0_0#topic">spec</a>, it should be about 2 uA.</p><div style="clear:both;"></div>
