Hi King, I reported your request internally. But I don't think we will have that updated in the SDS soon. You may have to think ab other solution for current calculating.

thanks！I know there a Probability problem。maybe it is difficult to calculate。but if I can’t get the basic process，I can‘t research the Probability problem。so I hope you can provide the process picture and show some current parameter it it 。just need a eg picture。thanks ！

I afraid even with the graph it will be hard to really calculate the average current consumption. The reason is that the rate how often the scanner capture an advertising packet and send the request (and receive a response) is not easy to calculate. It's depends on lots of criteria, such as advertising interval, scan window, scan interval, and the random advertising delay added.

You can have a rough number of current consumption with common tool, such as the multimeter. Note that if you are concern ab the peak current, you can get the peak current by having a look at the TX current and RX current it should be the same as when doing normal scanning or advertising etc.

by the way，I‘m A POOR guy，I have no money buy PPK.PPK is in my dream life。wuwuwu。。。

Hung Bui，thanks！ I want to calculate the master consume more accurate。and research the influences about Broadcasters to the master energy consume

Hi King,

We don't have that for now. I can send a request to the team to think about adding more figure in the next version of the SDS.

May I ask what do you plan to do with the data? I guess it has something to do with the timing ?

If you simply want to do current measurement you can use the PPK kit as suggested in your another case.
