4. Start the wpa_cli to issue the p2p commands
wpa_cli -i p2p0
5. Scan the GO MAC address to connect and issue command for time for scan
completion
p2p_find 20
6. The MAC address of all the devices found will be listed using the command
p2p_peers
7. To start a persistent group
p2p_group_add persistent freq=2 ht40
freq=2 means 2.4 GHz network.
freq=5 means 5GHz network.
8. If the autonomous GO is started successfully, then the P2P GO device will be in
connected state. To check the status,
status
9. Scan from the p2p client device and issue the connect request to GO MAC
address. In GO device issue the connect command to the client device address
along with the PIN generated by the client address
p2p_connect <Client MAC address> “pin_value” go_intent=15
10. Run the dhclient in the P2P client device and check the data transfer between P2P
GO and client devices.
Throughput Measurement
iPerf is a tool used to measure the maximum TCP/UDP throughput. For peak performance,
tests are conducted in RF chamber or in a less crowded environment.
UDP Throughput Test Procedure in Station Mode
•
Bring up WE866C3 Wi-Fi NIC module (say STA#1) and connect to an AP
•
Connect one of the PC/Laptop (say STA#2) to the same AP through an ethernet
cable
•
Disable power save in STA#1
sudo iw dev wlan0 set power_save off
•
Start UDP server in STA#2
iperf -s -u
•
Ping STA#2 and make sure the link is up and ARP is resolved
•
Now issue the following command in STA#1
>iperf -u -c <IP address of STA#2> -t 60 -b 100m
