SL_NETAPP_IPV4_IPACQUIRED_EVENT not always received

Other Parts Discussed in Thread: CC3100

Hello,

Using the CC3100 with SimpleLink running in station mode, I am able to receive the SL_WLAN_CONNECT_EVENT event in my SimpleLinkWlanEventHandler() handler, however, I very very rarely ever receive the SL_NETAPP_IPV4_IPACQUIRED_EVENT in SimpleLinkNetAppEventHandler.  I am using the same code as the WLAN Getting Started example and have been through all of the discussions here related to this issue.  Others have had this same issue.

The brand of my AP is a Motorola SBG6580. 

I switched over to using a TP-Link TL-WR1043ND and everything works fine.

It is my understanding that the CC3xxx team would like for this to work on all WiFi APs, so this is another datapoint for you guys. 

If you have any tips or suggestions on how I can get this to work on the Motorola AP, please let me know.  I have tried all of the settings with no improvement. 

When logged into the Motorola AP, I can view the list of connected DHCP clients and can sometimes see my CC3100's MAC address listed (even though no SL_NETAPP_IPV4_IPACQUIRED_EVENT event is received).  Connection to the AP is not a problem.  The SL_WLAN_CONNECT_EVENT is always received and pretty quickly.

Thanks,
-sh

    More info: If I change the security type to OPEN for the Motorola SBG6580, then I can fairly readily receive the SL_NETAPP_IPV4_IPACQUIRED_EVENT event. I normally run with WP2_PSK with AES encryption. For the TP-Link, I was running in OPEN mode. I will try using a secure mode and see if I experience the same flakiness.

    Hi Sh,

    You are correct - we are committed to have SimpleLink to work with any Access Point (as long as it doesn't violate specs).

    Regarding your use case - Are you seeing the issue after number of connections or from the first connection?

    Which version are you using ?

    Also some more information can be found in here: 

    Best Regards,
