Sorry but i'm noob in diy hardware. The Bluetooth module has four pins 1 is TXD 2 is Gnd 3 is VCC 4 is KEY and then there are 2 missing pin one is RXD and one is STATE. I know that pin4 of vga connector goes to rx pin 7 to ground and pin 11 to tx but i'm little confused the key and the state pin are for what?In which pin i've to connect the power? Another question can i use a pc USB port instead of the USB tv port for provide the necessary 5v?The wiki explain only the wired solution but nothing much about wireless one. Thanks.

All what you need on this bt module: rx, tx, gnd - connect to VGA corresponding pins (rx-tx, tx-rx, gnd-gnd). You can use 5v from TV`s USB port VCC +5 - GND. I wouldnt recommend you to use your pc`s usb port for this goal.
