Low-power system design with AIROC™ Wi-Fi & Bluetooth® combo
chip and PSoC™ 6 MCU
Power measurement using CY8CKIT-062S2-43012
5. Open a command prompt and ping the IP address displayed on the serial terminal:
The network stack is resumed. The device displays the Deep Sleep and Wi-Fi SDIO bus statistics on the
terminal. The LED toggles after resuming the network stack, after which the network stack is again
suspended until network activity is detected.
The host MCU will wake up on any network activity and not necessarily because of the ping from the PC. The
reasons for network activity can be because of the broadcast or multicast packets issued by the AP. Further
power savings can be made by employing offload features such as packet filtering, which will increase the time
the host MCU will be in Deep Sleep.
