CC3200 P2P Application

Overview

This sample example demostrates how CC3200 connects to a P2P device. The application starts a TCP server on port 5001 and waits for P2P device to connect and send data on it.

Different supported P2P roles of CC3200 are:

• SL_P2P_ROLE_GROUP_OWNER: CC3200 will be configured in 'Group-Owner' mode
• SL_P2P_ROLE_CLIENT: CC3200 will be configured in 'Client' mode
• SL_P2P_ROLE_NEGOTIATE: CC3200 will negotiate with remote device for client/GO role.

CC3200 can be configure in below modes to initiate negotiation:

• SL_P2P_NEG_INITIATOR_ACTIVE: CC3200 will perform discovery - Once the remote device is found, it sends the negotiation request immediately
• SL_P2P_NEG_INITIATOR_PASSIVE: CC3200 will perform discovery - Once the remote device is found, CC3200 waits for it to start negotiation
• SL_P2P_NEG_INITIATOR_RAND_BACKOFF: CC3200 will perform discovery - Once the remote device is found, it triggers a random timer (1-7 seconds) and waits for the remote device to negotiate. On timer expiry, CC3200 starts negotiation itself

Supported security types used during p2p negotiation are:

• SL_SEC_TYPE_P2P_PBC
• SL_SEC_TYPE_P2P_PIN_DISPLAY
• SL_SEC_TYPE_P2P_PIN_KEYPAD

CC3200 can be configured in 'any_p2p' mode as well - When configured, CC3200 will perform discovery and connect to the first found device using security type 'SL_SEC_TYPE_P2P_PBC'

Application details

The example intends to demonstrate how p2p mode can be configured and used. Application configure the device with following settings:

• P2P role negotiate (SL_P2P_ROLE_NEGOTIATE)

#define  P2P_ROLE_TYPE_NEGOTIATE

• P2P negotiation initiation active (SL_P2P_NEG_INITIATOR_ACTIVE)
• P2P device listens on channel 11 and P2P device's operation channel is set to 6
• P2P connect security type 'PBC'

Usage

• Open a terminal program (like teraterm) and configure it w/ '9600' baud rate.
• Build and run the application
• Start remote P2P device

   CC3200 will be visible as P2P_DEVICE_NAME (which is set in the sample application) to the remote P2P device

• Connect to CC3200. On successful connection, CC3200's IP address will be displayed on the terminal-program's console

• Open an 'Ipef' client on the remote P2P device and connect on 'PORT_NUM'

   Iperf.exe -c <DEST_IP_ADDR> -p <PORT_NUM> -i 1
