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
( not supported )
•
Period : 10msec
•
Voice sampling : 16khz 16bit

* RF Pairing / Un-pairing Method
Method
Description
RF Pairing
Method1
–
If unpaired, just press "OK" button.
–
If paired, press "OK" button after
unpairing.
Method 2 (Repairing)
– Press “BACK" button for 5 sec.
•
When do pairing, the remote should make pairing
request IR signal(0x29) to TV.
•
When TV receive the IR signal, it should send "pairing
request packet" to the RF receiver.
•
After pairing success, the remote should blink LED for
some time and TV send "pairing success packet" back
to TV.
•
When remote try to unpairing, it doesn’t care about
state of receiver(stand alone).
RF Unpairing
Press “HOME" button and “BACK" button
at the same time for 5 sec.
•
When remote try to unpairing, it doesn’t care about
state of receiver(stand alone).
•
After unpairing, all pairing information should be erased.
•
After unpairing, LED should be blinked for 3sec.
•
The remote just becomes to IR mode.
