Hi, Liang
There is one issue in this part.
When you find one frequency level can't be support on the server
we used, you return directly. This will skip the set_policy step in the following.
If skip the set_policy step, the behavior will be the power lib always
execute the training steps, even we set the policy.state=MED_NORMAL in the sample.
This will confuse the user, they don’t know why they can't skip the training steps even
the sample is already configured to --empty-poll=0,xxxxx,xxxxxx
BRs
Lei
