Project #041: Low-Power Modes on PSoC 4 BLE

In today's project, we demonstrate how to use the low-power modes on PSoC 4 BLE.

Recall from project #027, PSoC 4 BLE has five flexible low-power modes with various resources that are available or turned off in those modes, allowing the user to design for optimal power consumption.

In this project, the device can switch between the Active, Sleep, and Deep-Sleep power modes. The BLE subsystem in the chip is also independently controlled to be in its low-power modes whenever suitable.

A BLE Client, the CySmart USB Dongle in this case, it used to send commands to the PSoC 4 BLE device to switch between its low-power modes.

In the Active mode, this project consumes 5.8-mA of current. In the Sleep mode, the current consumption drops down to 3.35-mA. In the Deep-Sleep mode, the current consumption drops down further to only 0.03-mA while still maintaining the Bluetooth Low Energy connection.
