System, ™ Motion Data Transmission | LG Electronics 640T-ZA specification

1. System

	UART
RF	or USB

Remote	RF Receiver	TV

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)

•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.

Motion Data Transmission

•Period : 7.5msec

•Motion Data : gyro, accelerometer

Voice Data Transmission

•Period : 10msec

•Voice sampling : 16khz 16bit
