RTOS/CC3220S-LAUNCHXL: [Event] STA disconnected from AP fired twice with Reason Code = 3 and Reason Code = 202

Zac

Tool/software: TI-RTOS

While testing the provisioning example, the connection is successful to the AP and ping results came as expected. However sometimes when the AP is turned off, there are two disconnect event fired with different reason code.

[Event] STA disconnected from AP (Reason Code = 3) & [Event] STA disconnected from AP (Reason Code = 202)

From wlan.h the codes refers to 3 --> SL_WLAN_DISCONNECT_DEAUTH_SENDING_STA_LEAVING and 202 --> SL_WLAN_DISCONNECT_AUTH_TIMEOUT

I am not using any authentication mode nor secure modes, hence I think these codes are incorrect for usual wlan disconnection. It is also causing issues in my programming cycle.

Appreciate if someone can help me with this.

Hello,

You mentioned that the AP is off which makes sense to get disconnect messages.

Why is it causing issues?

The AUTH message you get is not related to secured AP but to the AUTHENTICATION process which is the initial step in connecting to any WiFi network.

Please clarify.

Regards,

Shlomi

Thanks for the details Shlomi. Any reason why 202 event is fired randomly (timeout) ?

Is it only the 202 errror code or the other one as well?

To understand more regarding the AP disconnection, an air sniffer is required.

Error Code 202 appears randomly, where as 3 appears in all cases.
I have tried AP disconnection from different AP's and the result seems to be similar, i.e I get error code 3 and 202 (randomly).
