CC3301: STA - Disconnection event, Reason 0x01 ( WLAN_DISCONNECT_UNSPECIFIED )

Julien bouille
Prodigy 80 points
Part Number: CC3301

Tool/software:

I got an MCU interfacing the CC3301 using last R5 driver version. 

unfortunately, i am facing disconnection event in the driver from the access point i am connect to. This event sometime occure quicly or sometime after 20 minutes so this is quitte hard to reproduce. 

The disconnection event reason is 0x01 so Unspecified ... 

Attached are CC3301 log output. i can see that multicast frames counter is inceasing, could this be the reason ? the driver seem to be unresponsible after the disconnection occure.

    HEllo,

    Can you share the AP model and settings?
    Can you also try and get FW logs out of the LOG pin?

    We will be releasing a new version in the next 2 weeks which will include many stability and general bug fixes with improved error logging capabilities also.

    Hello, 

    thanks for your response. 


    the log output bellow is a capture of when the moment error occurs

    AP is a Asus router with WIFI secur mode in WPA3 mode.

    Do you know when a final release is expected for firmware ? 
    thanks

    Let's get you past the scan issue on the other thread and see if you still see this issue on R7.
    If it is let's re open a new thread for R7, I am hopeful we can get you resolution.
