How is the power consumption on NRF52840 DK with project peripheral Blinky in connecting mode?

[george079]

I measured the power consumption on NRF52840 DK with project peripheral blinky (SDK15.0.0). The average current is 704uA and the base current is 680uA when connecting to another RF52840 DK with project central multilink .

I tried to make the connection interval become to 1000ms ( 200ms original ) and it made the average current lower to 690uA.

Does NRF52840 go into sleep in connection interval in project peripheral blinky ? 

How could I reduce the base current 680uA ?

Yes, the chip will go to sleep in between connection intervals. However, I do not think the vlinky app is power optimized, also if LED's are turned on it will use more power. Consider using the Power Profiling Application if you want to measure current for given scenarios.
