Pairing Information Transmission (Send to TV after Paired)
• Static Calibration Data (Bypass only)
• Remote FW ver. (Save also in Receiver)
• BD_ADDR (Save also in Receiver)
• 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.
• 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.
