•
Remote FW ver. (Save also in Receiver)
•
BD_ADDR (Save also in Receiver)
• Pairing Information Transmission Sequence
•
When it is paired, the remote sends packets(pairing success, F/W version, BD_ADDR) to the receiver.
•
The receiver sends the pairing success packet to TV directly.
•
F/W version and BD_ADDR packets are just saved on the receiver.
•
The receiver sends F/W version or BD_ADDR packet to TV when it is required.

Period : 7.5msec
•
Motion Data : gyro, accelerometer
Voice Data Transmission
