Designing for Low Power and Estimating Battery Life for BLE Applications
5 Summary
PSoC 4/PRoC BLE devices support multiple systems and BLESS low-power modes that enable you to design a
highly power-efficient solution. The advertising and connection current profiles indicate that the Deep-Sleep mode
current is equally important to the RF transmit/receive currents when considering a reduction in the overall average
current. The advertising and connection power calculator can help you choose the right set of parameters.
The battery life of a BLE application depends on the system-level current consumption. In most applications, sensing
and processing can consume more power than the BLE operations, so attention must be paid to reduce the overall
system current. The system-level low-power techniques suggested should help you in designing a low-power BLE
solution by including some suggestions, where possible, at the system design stage. You can also use the power
calculator tool to help you make decisions on the system parameters to improve the battery life.
