Advertising consume more power compared to connection?

[Ziyao Zhou]

Hi,

I am sending out same payload through ADV packet and BLE connection packet, I notice the ADV consume more power compared to connection one,which is quite strange.

The result I have is here, is this correct? What is the reason, thank you so much!

Radio on-time is a bit shorter in the "connected" case if - and only if- there is no or very little data to exchange.

Remember that connectable advertizer has to listen to scan request or connect attempts after each advertizement, so the radio will spend some time in RX mode.

In addition to Jörgs great answer, you can also have a look at the Online Power Profiler, which shows detailed graphs of how the nRF uses Power. Here you can compare Connected and Advertising state.
