Bluetooth Low Energy power profiles

The power profile diagrams in this chapter give an overview of the stages within a Bluetooth® Low Energy Radio Event implemented by the SoftDevice. The profiles illustrate battery current versus time and briefly describe the stages that could be observed.

The profiles are based on typical events with empty packets. The Standby is a state of the SoftDevice where all Peripherals are IDLE.

The time the radio spends to transmit or receive a packet depends on the PHY. Using a higher data rate will decrease the radio time, while using a lower data rate will increase the radio time. Therefore, a higher data rate decreases power consumption, while a lower data rate increases power consumption.

Note: A higher data rate increases throughput but reduces the link budget and therefore the maximum range. A lower data rate decreases throughput but increases the link budget.
