Senior xda member s107ken
has enabled Miracast for the Nexus line.
He has a great write up in his github here
. He includes code for the WFD (wifi display) settings menu, modifications to framework (av and base) to modify the Nexus tablets. This might be helpful to enable Miracast for the Nook Color. As mentioned in my post above, the nook color doesn't have p2p configured in the wifi supplicant. It's one thing to be able to connect to a Miracast enabled receiver (TV, projector). It's another thing to be able to stream wireless content mirroring the nook color to the receiver. Most Miracast dongles connect to the HDMI port of the receiver. Don't know if there are USB3.0 versions. These dongles use H.264 video codec for 1080hd/5.1 Dolby Surround.
