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.

These profiles are based on typical events with empty packets. In all cases, Standby is a state of the SoftDevice where all Peripherals are IDLE. Using a higher data rate physical layer (LE 2M PHY) increases throughput and thus allows the RADIO to be IDLE for a longer time. This will significantly reduce the energy used to send and receive data. Using a higher data rate physical layer will reduce the link budget (range).
