Test case for iperf example.
|
|
|
|
This test case might have problem running on windows:
|
|
|
|
1. direct use of `make`
|
|
2. 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"
