Configure the Simplicity Power Estimator Tool for BLE applications#

The Simplicity Power Estimator enables developers to simulate various operating scenarios by configuring parameters that reflect real-world application use cases. Based on the selected configuration, the tool calculates average current consumption and estimates battery life.

Step 1: Configure the Device#

Follow these steps to enter your device’s setup:

1. Choose a Battery Type#

  • Select a predefined battery profile, such as AA or coin cell.

  • To use a custom battery, select Custom... and enter the battery capacity in the Battery Capacity field.

2. Select an Application Type#

The estimator supports the following application types:

  • Beacon: Example of an iBeacon application.

  • Advertising: Base example that runs advertising.

  • Connection Peripheral: Example of an application that periodically initiates a connection and transmits a set amount of data before closing it.

3. Configure Application Settings#

The following settings are available for all application types:

Setting

Description

Supply Voltage

Sets the supply voltage to 1.8 V or 3.0 V (using the DC-DC converter in the chip).

DCDC Enabled

Enables the on-chip DC-DC converter to allow setting the Supply Voltage to 3.0 V.

The following settings are available for Beacon and Advertising applications:

Setting

Description

TX Power

Sets the intended transmit power for advertisements, in dBm.

Advertising Interval

Sets the interval of advertisements in milliseconds.

TX Payload

Sets the advertising payload size, in bytes.

The following settings are available for Connection Peripheral applications:

Setting

Description

Connection Interval

Sets the connection interval in milliseconds.

TX Payload per Event

Sets the transmitted payload size for each connection event, in bytes.

RX Payload per Event

Sets the received payload size for each connection event, in bytes.

PHY

Selects either the 1 Mbps PHY or 2 Mbps PHY.

Step 2: View the Results#

After you configure the application, the estimator calculates the following metrics:

  • Average Current Consumption – The estimated average current used by the device.

  • Estimated Battery Life – The projected operating lifetime based on the selected battery in the chosen metric.

  • Activity Breakdown – A diagram showing how much power each activity (such as sleep or data transfer) consumes.

Limitations#

  • Estimates are derived from measurement-based estimators.

  • Environmental influences and hardware variations (such as temperature or impedance mismatch) are not modeled.

  • The tool does not support runtime power profiling.
