Test case for iperf example.
|
|
|
|
This test case might have problem running on windows:
|
|
|
|
- use `sudo killall iperf` to force kill iperf, didn't implement windows version
|
|
|
|
The test env Example_ShieldBox do need the following config::
|
|
|
|
Example_ShieldBox:
|
|
ap_list:
|
|
- ssid: "ssid"
|
|
password: "password"
|
|
outlet: 1
|
|
apc_ip: "192.168.1.88"

iperf: "/dev/ttyUSB1"
