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
|
|||
|
|
|
|||
|
|

|

|
|||
|
|
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
|
|||
|
|
