What is the power consumption when scanning is turned on

[helen]

Hi

           In the actual test, the power consumption of the chip when scanning is started  is 9.5mA,This actual test value is higher than the Iradio_rx0 and Is1 in the PS .What is the difference between Iradio_rx0 and Is1 , and which of them represents the actual power consumption of the ble scan?Is the actual test value of 9.5mA normal?

Hi,

What supply voltage are you using? Is the DC/DC active, and Is any other peripheral running? Could you share the code that you use?

Hi

         Sorry！

       1、I know whether DC-DC is enable and whether peripherals are running will affect power consumption，I can analyze these；

        2、I just want to know the difference between IRADIO_RX0 and IS1 in application and Which is the power consumption of the scan window（BmA-AmA)，How to confirm CPU running coremark from flash and  Cache enabled？Does enable ble scan require the CPU to run coremark from flash and enable cache?

I'm not sure what you mean by this. The current consumption depends on several factors such as DC/DC, supply voltage, external HFXO crystal etc

IRADIO_RX0 is specified with the following conditions when nothing else is mentioned:

You therefore have to measure with the same conditions on your board. 6.5 mA is representative of what the current draw should be when the nRF52832 is scanning, given that the mentioned conditions has been met. 

IS1 is the current draw when the CPU is running the benchmark test CoreMark. It's not the same as IRADIO_RX0 , it's also not supposed to be used in a common application. It's just for presenting comparable statistics- about the current draw of the nRF52832.

Ok，Thank you very much！
