Summary: - I noticed that lc823450-xgevk:rndis does not work with iperf - Finally, I found that it does not call pthread_join() - This commit fixes this issue Impact: - No impact Testing: - Tested with lc823450-xgevk:rndis - NOTE: need to add iperf in the defconfig Signed-off-by: Masayuki Ishikawa <Masayuki.Ishikawa@jp.sony.com> |

Configuring NuttX to use your Wireless Router (aka Access Point)
Since you are already in the root of NuttX/ repository, execute
make menuconfig to define your Wireless Router and your password:
$ make menuconfig
Browser the menus this way:
Application Configuration --->
Network Utilities --->
Networking Configuration --->
WAPI Configuration --->
(myApSSID) SSID
(mySSIDpassphrase) Passprhase
Replace the SSID from myApSSID with your wireless router name and
the Passprhase with your WiFi password.
Exit and save your configuration.
iperf Test Example
To set up, do make menuconfig and select the Apps > netutils > iperf example. By default, NuttX will the be the client
which sends data; and the host computer (Linux, macOS, or Windows) will be the server.
Set up networking so the NuttX computer can ping the host, and the host can ping NuttX. Now you are ready to run the test.
If you are using a wireless network card, you must first connect to the router:
On host:
$ iperf -s -p 5471 -i 1 -w 416K
------------------------------------------------------------
Server listening on TCP port 5471
TCP window size: 416 KByte
------------------------------------------------------------
On NuttX:
nsh> iperf -c 192.168.1.181 -p 5471 -i 1 -t 10
mode=tcp-client sip=192.168.1.198:5001, dip=192.168.1.181:5471, interval=1, time=10
Interval Bandwidth
0- 1 sec, 0.39 Mbits/sec
1- 2 sec, 0.26 Mbits/sec
2- 3 sec, 0.39 Mbits/sec
3- 4 sec, 0.26 Mbits/sec
4- 5 sec, 0.26 Mbits/sec
5- 6 sec, 0.26 Mbits/sec
6- 7 sec, 0.26 Mbits/sec
7- 8 sec, 0.26 Mbits/sec
8- 9 sec, 0.26 Mbits/sec
9- 10 sec, 0.26 Mbits/sec
0- 10 sec, 0.28 Mbits/sec
Now on the host you should see something like:
$ iperf -s -p 5471 -i 1 -w 416K
------------------------------------------------------------
Server listening on TCP port 5471
TCP window size: 416 KByte
------------------------------------------------------------
