Hi Nishant,

I would suggest that you use the calculator in nRFgo Studio, as this is a bit more accurate and it's an official tool from Nordic. You can download the nRFgo Studio application freely from our website: www.nordicsemi.com/.../nRFgo-Studio

Input the numbers for your application and you will get an approximated current. You will have to add current consumption of your external MCU.

Best regards Håkon

Hakon,

I do not have the nRFgo Studio, sorry I didn't tell you about that! Actually I have nrf8001 on my custom PCB and not the development kit offered by Nordic.

Also I have an app(on Google Play!) for nrf8001 current calculation ,under its Connection state current calculator I have the following options :

Crystal tolerance : which I selected 40ppm depending on the crystal Im using.

and deselected the 32khz crystal as Im using a 32khz crystal external one and not the internal one. battery capacity as 50mAh as using a coin cell.

and connection interval as 120ms.

I want to know for example that if the nrf8001 is connected everyday to a mobile device for around 10minutes everyday and connection on an average happens for 5 times then what could be the average current draw?

Hi,

Have you looked at the nRF8001 current consumption calculator that's embedded into nRFgo Studio (top left corner, click on "nRF8001 Configuration", and then you should see a tab called "Current Consumption" in the right corner)? That should give you a indication on what the current consumption should be.
