This file contain simple example how to
use and tests remote clients.
1) .config file should include CTRL UDP configuration
eg. udp-remote
2) you should be able to login/execute command to
remote hosts using authorized-keys.
eg. ssh root@hostname id
In this example we simply setup AP (open) and next
connect to this ap, next connectivity (ping) is
validated.
eg. test for hwsim
modprobe mac80211_hwsim
./remote_test_example.py
