OMAPL138 Wireless Connectivity Demo
Contents
Description[edit]
- This section walks through basic Wireless LAN demo scenarios.
- The WLAN is operational through the CLI that is running over Terminal
- Bluetooth is not functional
- GUI is not functional with that release
Prerequisite[edit]
It is assumed that the hardware and the software are already installed, otherwise please refer to the <AM18 Getting started guide>
In addition make sure that a Calibration is performed before the first time working with WLAN on that platform.
For Calibration procedure please refer to the following links: <AM18x Calibration process>
Turn on the EVM and log on as "root".
Demo Menu[edit]
Step 1. Power on
Step 2. Demo scenarios
Step 3. Operate the WLAN Menu from CLI
Step 4. connect to non secured WiFi network
Step 5. connect to secured WiFi network - WPA
Step 6. connect to secured WiFi network - WPA2
Step 7. Getting IP address
Step 8. WLAN PING test
Step 9. WLAN Throughput test
Demo scenarios[edit]
Below are the Bluetooth and WLAN scenarios that are supported in this demo
| senario | description |
|---|---|
| Connect to non secured WiFi network | Non secured WiFi network |
| Connect to secured WiFi network | WPA WiFi network |
| Connect to secured WiFi network | WPA2 WiFi network |
Hardware Setup[edit]
To run this demo you need the following:
- another PC connected to your Access Point with an Ethernet cable
- Connect PC via serial port in order to run the CLI (Commands Line Interface) to run WLAN commands)
- the Flat cable in the Picture below is used for Bluetooth therefore not needed for OMAPL138
Power on[edit]
connect the EVM to terminal using the serial port, and then turn on the Power.

Getting IP from Access Point - DHCP[edit]
To get the IP from the DHCP Server follow the below given step
root@am180x-evm:/usr/share/wl1271-demos/wlan# udhcpc -i tiwlan0 udhcpc (v1.13.2) started Sending discover... Sending select for 192.168.13.146... Lease of 192.168.13.146 obtained, lease time 14400 adding dns 192.168.10.51 adding dns 192.168.10.54 root@am180x-evm:/usr/share/wl1271-demos/wlan#

root@am180x-evm:/usr/share/wl1271-demos/wlan# ifconfig tiwlan0 192.168.13.146
WLAN PING test[edit]
This section assumes that the EVM is already connected to the Access Point, otherwise return to < return to Menu> to start the WLAN driver and connect to a non-secured WLAN network.
Running the demo[edit]
Configure the EVM WLAN IP address, and make sure that the EVM Ethernet port and WLAN port will not share the same IP subnet address.
root@am180x-evm:/usr/share/wl1271-demos/wlan# ifconfig tiwlan0 192.168.13.11 netmask 255.255.255.0 up
verify that the WLAN port (tiwlan0) IP address is configured correctly

Configure the IP address of the Laptop that is connected to the Access Point via the Ethernet cable to be in the same subnet as the EVM WLAN port. In this example, we configure it to 192.168.13.68, and the gateway IP address is not important for this test
then use the Ping command to ping the PC that is connected to the Access Point
root@am180x-evm:/usr/share/wl1271-demos/wlan# ping 192.168.13.68 PING 192.168.13.68 (192.168.13.68): 56 data bytes 64 bytes from 192.168.13.68: seq=0 ttl=128 time=64.925 ms 64 bytes from 192.168.13.68: seq=1 ttl=128 time=2.698 ms 64 bytes from 192.168.13.68: seq=2 ttl=128 time=2.560 ms --- 192.168.13.68 ping statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max = 2.560/23.394/64.925 ms root@am180x-evm:/usr/share/wl1271-demos/wlan#
Similarly, we can ping to the EVM from the PC connected to the Access Point via Ethernet:
WLAN Throughput test[edit]
Hardware Setup[edit]
To run this demo you need another PC connected to the Access Point with an Ethernet cable, as shown below. To measure the throughput use the iPerf tool, and in this example we use only UDP downstream - i.e. UDP packets from the PC connected to the Access Point to the EVM.
This section assumes that the EVM connected to the Access Point, otherwise return to < return to Menu> to start the WLAN driver and connect to a non-secured WLAN network.
Iperf tool[edit]
In order to measure the throughout we are going to use the iPerf tool that is already installed on the EVM, and a graphical version of the iPerf tool called "IPerf" which runs on the PC side.
Running the demo[edit]
root@am180x-evm:/usr/share/wl1271-demos/wlan# ifconfig tiwlan0 192.168.13.11 netmask 255.255.255.0 up

Configure the IP address of the Laptop that is connected to the Access Point via the Ethernet cable to be in the same sub net as the EVM WLAN port. In this example, we configure it to 192.168.13.68, and the gateway IP address is not important for this test.
Then use the iperf command to run iperf server on the EVM. In this example, we expect to receive UDP packets at port 7000 and print the results on the screen every one second
root@am180x-evm:/usr/share/wl1271-demos/wlan# iperf -s -i1 -p7000 -u
As a response to the previous command, we will see that iperf has started and ready to receive UDP packets
------------------------------------------------------------ Server listening on UDP port 7000 Receiving 1470 byte datagrams UDP buffer size: 106 KByte (default) ------------------------------------------------------------
Now operate the iPerf client on the PC that will send Packets to EVM via the wireless medium. Configure iperf to:
- Client
- UDP
- port 7000 (same as server configuration on the EVM)
- send packets to server ip:192.168.13.11 which is the EVM IP address
- UDP Bandwidth 30 MBytes/sec
After starting the iPerf client in the PC side, you may see the Server on the EVM starts receiving frames. In this example the throughput is about 13.5Mbits/sec. Note that you would expect to have a higher throughput if you were working in a clean environment like an RF chamber.
