CC3220S: The CC3220 didn't respond with Probe Response in AP mode

Part Number: CC3220S

Hi experts，

I set CC3220 into AP mode(channel 1 with 'EU' CountryCode or channel 13 with 'EU' CountryCode), use a smartphone to scan this AP. But it didn't respond with 'Probe response' according to capture files.

Attachment is my captured file which could be open with Wireshark, and smartphone MAC is: 50:8f:4c:f9:e7:ac, CC3220 MAC is: 0c:ae:7d:cd:4b:26

Hi,

Do you use own hardware or LaunchPad? Please try to reproduce issue with network_terminal example from latest SDK. Make sure that latest service pack is uploaded as well.

Few days ago I had a similar issue in AP mode. Issue was caused by mistake in my code. Repeatedly calling of sl_WlanGetNetworkList() was causing such kind of issue.

For additional diagnosing of issue may to be useful capture NWP and MAC log.
