Original question:

CC3220: CC3220 disconnected from AP with error SL_WLAN_DISCONNECT_FRAME_FROM_NONASSOC_STA

CC3220S: Which Power Policy of CC3220's networking subsystem is suitable in scenario of connected to a AP

Part Number: CC3220S

I have a following scenario: CC3220 used in an IoT endpoint device, it should connect to an AP and keep application layer connection with remote server by 10 second period heartbeating. Occasionally, it will lost connection. I use Power policy of Low power for Networking subsystem.  It recommend in "Networking Subsystem Power Management" page 9, the Low power policy is not suitable for connecting to AP, it was used in transceiver mode. So should I use Normal(default) policy instead of Lower power policy in my scenario? Thanks

    Hi,

    Your scenario is best suited for either the Normal power policy or the Long Sleep Interval power policy. The difference between the two is when the device decides to wake-up. With the normal power policy, the device will just set the wake-up timing based on the access point's parameters (beacon interval/DTIM interval). For the long sleep interval policy, the device can be configured to skip an integer multiple of DTIM periods to reduce the overall power consumption.
