hello!
I have a question about the AT command.

Test Example]


[SSID] Secure public Wi-Fi
[BSSID] 0x6:0xa:0xde:0x15:0x20:0x6d
[Security Type] WPA_ENT
[SecurityKey] WIFI
[SecurityExtUser] WiFi
[SecurityExtAnonUser] wifi
[SecurityExtEapMethod]PEAP0_MSCHAPv2

Enter the AT command :


AT+WlanConnect=Public
WiFi Secure,0x6:0xa:0xde:0x15:0x20:0x6d,WPA_ENT,wifi,wifi,wifi,wifi,PEAP0_MSCHAPv2

OK

+eventwlan:disconnect,Public WiFi Secure,0x6:0xa:0xde:0x15:0x20:0x6d,209

+eventwlan:disconnect,Public WiFi Secure,0x6.0xa:0xde:0x15:0x20:0x6d,1

Please let us know what is wrong with the above event

Also, please check if CC3235MODSF can support WPA2_ENT.

    209 means SL_WLAN_DISCONNECT_MISSING_CERT (see in wlan.h).
    You should include the server root ca cert in the cc32xx file system ("/sys/cert/ca.der" - see chapter 4.6.2 in the programmer's guide).
    But please note that this will only solve the current issue.
    CC3235 is not recommended for enterprise connections as it can only support TLS1.0 which is now obsolete. Due to limited patching resources (CC3235 is a ROM device) the device can't be be upgraded to support TLS1.2 as needed (the limitation is only in regards to enterprise connections. the secure socket connection does support TLS1.2).
