Equation for 'Online Power Profiler for BLE' Tool

Hi there,

I am looking for the equation that is used in the Online Power Profiler for BLE tool to calculate the average current consumption.

We are selling a BLE device where the customer has the option of configuring the same radio parameters. We provide an app for this and we would like to present the user with an estimated battery life depending on the configuration values they have chosen in the app.

I am aware of this post which details some parts of the equation, however, I think the online calculator has since been updated to include other parameters that are not included here.

The only parameters which the customer can configure are the Tx power and the advertising interval, everything else is set by us. Our design closely follows the Nordic reference design so whichever configuration we chose, the real current consumption closely matches the estimated current consumption by the online calculator.

Thanks,

Sean

  • Hi, the Online Power Profiler consists of several models emulating the internal modules (analog domain, digital domain, regulators, etc) in the nRF52. Since the models reveal some of the inner workings of the nRF52 they are confidential and cannot be shared. These models are also quite complex and cannot be translated into single equations for others to use.

    You will have to extract the relevant numbers from the OPP webpage and add them to your model.

    Of course I can help you with general equations for estimating battery life, if I misunderstood your question.
