Is there any formula for current measurement for nRF51 dk?

[bikash]

I am using a nRF51822(pca10028) for current measurement. I had set up the devices as told in user guide. I am using SDK 11.0, softdevice s130 and default ble_app_pwr_profiling app from examples for current measurement. What are the measurements that I should expect from my set up?Any formula for current measurement with this or other apps to calculate current consumption?

Thank you for your all inputs @ToTo. I followed all that tutorial and did accordingly. I got current consumption for single advertising event ~4 mA and for single connection event ~2.5 mA using oscilloscope. Now I have another question: is there any way to calculate current consumption theoritically (meaning calculating using values/parameters we used in code like interval,tx power,rx power, slave latency,rx payload, tx payload, clock accuracy ) so that we can compare our practical result with theoritical result?

Sorry, i clicked on convert to a answer by accident.

Listen, i'm doing the same thing , i did an theorical and practical calculation of my app and i used the stuff i showed you : the BLE profiles (i used only the ADV profile and Connection peripheral event profile as they are in the nordic discription because in my app i use only those ones) and i got a very logic results with difference of about 0.5 mA between theorical and pratical (that's logic because i work on worst case when using theorical values).

All i did, is refering to the link i mentioned before in my comments. just do some effort you will find all there..

When you measured with the oscilloscope (the ADv events for example), did you find a profile like mentionned in Nordic description ? ( minimize the time division with push-zoom in the oscilloscope )

how did you find 4mA? do you mean you get it directly by reading form oscilloscope ? if that's what you mean so i don't think it's right. You have to zoom as i told you, and find the different stages discribed by nordic , and calculate each stage current then calculate the current average ( integral calculations )
