Here is my second attempt to miracast the nook color.
I started this time with CM-11-Snapshot-M6. My previous attempt was made on an unofficial compiled ROM with modifications made to init.encore.rc, but there was a conflict with wifi and p2p due to the single-role firmware loaded (wl127x-fw-4-sr.bin ver. 220.127.116.11.139). Removing the single-role firmware does not work. There is an error message in dmesg stating wl12xx cannot find wl127x-fw-4-sr.bin. To get the multi-role firmware wl127x-fw-4-mr.bin ver 18.104.22.168.47 to load, I stashed the single-role firmware, copied and renamed wl127x-fw-4-mr.bin to wl127x-fw-4-sr.bin and pasted to /etc/firmware/ti-connectivity/ (see dmesg pic). Rebooted. Wifi is working at this point. I'm connected to Netgear86. My sister's Sony Bravia tv is direct wifi capable (see wifi settings pic). Without making modifications to init.encore.rc, I used terminal in root mode to find the MAC address of the Sony Bravia tv.. The wpa_cli p2p commands were able to find the MAC address (see terminal pic). Wifi is still working at this point. One step closer to miracast for nook color.
