Tracing into the problem with the DMP, it looks like the library never gets past Chromecast->launch(). The LAUNCH message is sent but the response does not include a transportId. This causes the function to wait for another message which never arrives.
Also, the mDNS library does not find any devices (including any Chromecasts on the same subnet).
