CC3220SF: Power_enablePolicy

Amber He

Part Number: CC3220SF

Dear Community,

I bought a CC3220SF WiFi module from Shenzhen RF-star Technology. I have to use low power Wi-Fi.

I am programming it now. During this process, there are some problems. Here are my questions below.

The SDK is simplelink_cc32××_sdk_2_30_00_05.

  1. Power_enablePolicy can work normally in the main thread, but it cannot enter low power consumption if placed in the sub-thread. Later, when I added the WiFi, AP, STA mode toggle function, it can enter low power consumption in the sub-thread directly. However, after entering low power consumption in the sub-thread, it never wakes up and the printing stops either.

    The first figure is part of my log, and the second is when I enter the low power consumption in the sub-theard.

  2. The watchdog must be turned off to enter low power consumption. Is there any way to enter low power consumption without turning off the watchdog?

Thanks in advance for your assistance!

    Hi Amber,

    I advise you update to the latest SDK and try your application again. The latest SDK can be downloaded from this link:https://www.ti.com/tool/SIMPLELINK-CC32XX-SDK

    Please also ensure that you update the servicepack during the programming process to ensure you get the full set of fixes and features.

    There is some notes about running the watchdog and LPDS at the same time in this E2E thread: https://e2e.ti.com/support/wireless-connectivity/wifi/f/968/p/793152/2933627#2933627

    With the newer SDKs you should be able to use the watchdog and use LPDS at the same time without needing to reconfigure the watchdog timer before entering LPDS. As such, please update to the latest SDK version and see if you still run into the same issue.

    Regards,

    Michael

    Dear Michael

    I download the new version of the SDK, it work now. But here is a new problem come out.

    1. when i  use Power_disablePolicy function, it get stuck and cannot exit from low power consumption.

    2. And now I can run the watchdog and LPDs at the same time, but the watchdog doesn't work. The system has been stuck for a long time and the system will not restart.

    3. When I unload the SD card, it will also cause that I can't get out in low power consumption.

    i am a new guy to do this, pls kindly to help me. 

    Thank you for your patience.

    Dear Michael

    How are you? Here is a question about Cloud OTA. I am not very clear how to use it correctly. 

    I burned the code to the board and I didn't know how to connect GitHub for remote upgrade. Is there has some operation manulal for reference?

    Thanks in advance for your assistance!

    Hi Amber,

    As your issue with Cloud OTA is unrelated to the issue discussed in this thread, please make a new thread for your Cloud OTA question. We appreciate threads being contained and on-topic, to aid searchability for other E2E users.

    I sent you a servicepack through private message, please let me know here if it helps with your LPDS issues.

    Regards,

    Michael
