CC3100 P2P Application

Overview

This is a sample application demonstrating how CC3100 can be connected to a P2P device. This application starts a TCP server on port 5001 and waits for P2P device to connect and send data on it.

Different P2P roles supported by CC3100 are:

• SL_P2P_ROLE_GROUP_OWNER: CC3100 will be configured in 'Group-Owner' mode
• SL_P2P_ROLE_CLIENT: CC3100 will be configured in 'Client' mode
• SL_P2P_ROLE_NEGOTIATE: CC3100 will negotiate with remote device for 'Client/Group-Owner' role.

CC3100 can be configure in below modes to initiate negotiation:

• SL_P2P_NEG_INITIATOR_ACTIVE: CC3100 will perform discovery - Once the remote device is found, it sends the negotiation request immediately
• SL_P2P_NEG_INITIATOR_PASSIVE: CC3100 will perform discovery - Once the remote device is found, CC3100 waits for it to start negotiation
• SL_P2P_NEG_INITIATOR_RAND_BACKOFF: CC3100 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, CC3100 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

CC3100 can be configured in any_p2p mode as well - When configured, CC3100 will perform discovery and connect to the first found device using security type SL_SEC_TYPE_P2P_PBC

Application details

This application configures the device with following settings:

• P2P role negotiate (SL_P2P_ROLE_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

• Connect the board to PC and configure the terminal-program for seeing the logs. CC3100 & CC3200 Terminal Setting has detailed instructions for configuring the terminal-program
• Build and run the application
• Start remote P2P device (ex: Android device)

Note: CC3100 will be visible as P2P_DEVICE_NAME (which is set in the sample application) to the remote P2P device

• Connect to CC3100. On successful connection, CC3100's IP address will be displayed on the terminal-program's console

• Open an 'Iperf' client on the remote P2P device and connect on 'PORT_NUM'
• The Iperf version used in testing was: iperf-2.0.9-win64 (running on windows 10)

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

• See the self explanatory logs on the terminal-program's console. On success, below message will be displayed on the terminal

Note: User needs to reconfigure the device in 'Station-Mode' for executing other sample applications. Refer function configureSimpleLinkToDefaultState in this example's main.c for configuring the device in 'Station-Mode'.
