Hi All,
I want to implement a point-to-point connection for some data streaming. I would like to encrypt the data using AES which is part of WPA2. I am using the CC3200 as the group client and an Android tablet will be the Group Owner. I am developing using the CC3200-LaunchXL with the latest service pack and SDK1.3.0 (CCS v6.1.3.00034 if that matters). I have combined and modified the p2p and udp socket examples to get a working "open" test application, but I wanted to add some security. I see that WPA2 is supported, but it doesn't seem to be something I can set when using p2p. Here are the security settings that I tried:
secParams.Key = (signed char *)P2P_SECURITY_KEY; //(“PasswordTest”)
secParams.KeyLen = strlen(P2P_SECURITY_KEY);
secParams.Type = P2P_SECURITY_TYPE; //(SL_SEC_TYPE_WPA_WPA2)
lRetVal = sl_WlanConnect((signed char *) P2P_REMOTE_DEVICE,
strlen((const char *) P2P_REMOTE_DEVICE), 0, &secParams, 0);
ASSERT_ON_ERROR(lRetVal); //Asserts Error code -71
When I call WlanConnect to begin p2p Discovery Mode, I get an error -71 (SL_ERROR_INVALID_ROLE).
The connection process is the same as the p2p example code which works fine when the security is SL_SEC_TYPE_P2P_PBC with no password.
I have looked through examples and I can't find anything that explicitly shows WPA2 with Wi-Fi Direct and how to set it up.
Wi-Fi P2P Technical Specification v1.7 states, “The Credentials shall be fresh for each P2P Group formed. The Credentials for a P2P Group issued to a P2P Device shall:
-Use WPA2-Personal as Authentication Type.
-Use AES as Encryption Type…”
Anyone have some guidance here? Seems like I can only use WPS with p2p, but that's not what is called out in the tech specs for a Wi-Fi Direct capable device. Am I missing some other setting somewhere?
Thanks in Advance
