nRF51822 Average current consumption

[Rashid Talib]

Hi Where do I find a measurement report from Nordic which shows the average current consumption for a typical BLE application (1 seconds advertising period e.g.)?

Until now, I could not find any official AppNote or numbers even though it is a very essential key value.

TI measurement report for your reference: www.ti.com/.../swra347a.pdf

Thanks for your help & best regards

Hi there,

Section 8 of the SoftDevice Specification lists power profiles for both advertising and connection.

Section 8 of the nRF51822 Product Specification will give you concrete values for the currents referred to by the SoftDevice Specification.

I am not sure if that will cover what you require, but it should at least help provide some insight.

Regards,

Carles

Thanks for the hint Section 8.2 is informativ and gives an idea of realistic processing time and current values. But I still miss a pre-calculated description or comparison of different scenarios such as "Average current consumption with 1sec advertising interval" and the like.

However using chapter 8.2 it should be possible to do this calculations by oneself.

Best regards Rashid

I think what Rashid is hoping for, and I would love to see as well, is something similar to the nRFGO Studio tool for nRF800x devices that shows current consumption and battery life calculations for a specified advertising and connection interval profile.

Obviously, when you have user code running too, it's very hard to provide a complete power profile -- but at least having the Soft Device power consumption profile would allow developers to set expectations and look to tune power management in their own code/design.
