EventHub: How to set up HTTP or AMQP protocol?

I'm trying the BasicEventHubSample sample project to start with EventHub.

I was able to create EventHub programmatically but the "send message" part does not work. The error text gives me nothing. I'm working through VPN.

Maybe it is something with protocol? Maybe the managing commands are transferred by HTTP and the events - by AMQP? So maybe if I switch to the HTTP protocol, it would fix the problem?

So now I'm trying to switch from AMQP (which is the default protocol for sending/receiving events, isn't it?) to HTTP. How to do this?
