CYW920721B2EVK-02/ How to confirm whether CYW20721 is in deep sleep state or not.

[tayo]

Hello Infineon support team.

<Environment>

DUT: CYW920721B2EVK-02

Tool: ModusToolBox version 2.4

Reference App: Audio_Headset_and_Speaker

<Question>

We would like to configure CYW20721 to deep sleep mode.  To verify the deep sleep mode is working in the DUT,  how can we confirm?  

Ex)

- Can CYW20721 notify status log? 

 - Should we observe the current consumption?

Thanks,

Tayo

When the device enters deep sleep mode, the UART will turn off and no log output.

You can add some logs in the sleep_permit_handler callback. The device will enter WICED_SLEEP_POLL_SLEEP_PERMISSION event before sleep.

You can also spy the power consumption of the device.
