System Performance#

These pages address a variety of different topics related to improving system performance and reducing power consumption.

• Using the LFRCO as a Low-Frequency Clock Source: Describes using the LFRCO as the low-frequency clock source (instead of the LFXO) to wake up the device on each connection interval when sleep is enabled in the stack.

• Bluetooth TX Power Settings: Discusses how to configure TX power and how the actual TX power will change.

• Current Consumption Variation with TX Power: Discusses the current consumption for different TX power settings, measured on an EFR32BG13 during advertisement. The test result can be used as a generic guideline to set the TX power level in an energy-constrained system.

• Bluetooth Radio Task Priorities: Reviews using the radio scheduler to simulate running multiple tasks that use the radio at the same time.

• Setting a Custom BT Address - Production Approach: Explains two methods to modify the non-volatile region to set a custom BT address in production.

• Bluetooth LE Auto-PA Mode: Describes how to implement automatic switching between the PAs, when high accuracy output is needed both above and below 0 dBm.
