3.1 Pairing

3.1.1 Pairing Condition

1. RCU can perform pairing with 1 Sound Bar.

3.1.2 Pairing (Re-pairing) Scenario

Press and hold the BT button on the Sound Bar
Sound Bar LED will indicate RCU pairing mode, like flashing blue.
Press the RCU [Enter OSD Menu] or [Exit OSD Menu] Button for about 3 seconds to start pairing.
i. If the previous pairing information remains.
1. Send un-pairing command to the Sound Bar.
2. Delete the pairing information and start pairing.
ii. After pairing starts, advertise until Advertising Time Out.
1. Advertising Time Out is about 30 seconds.
2. Advertising Interval is about 30 ~ 35ms.
When the Sound Bar find the new RCU, deleting the previous pairing information and pairing with the new RCU.
When pairing is complete, all buttons of the RCU output RF code.

3.1.3 Reconnection (Disconnected State)

After pairing, when the power of the RCU is re-applied or the BLE connection between the Sound Bar and the RCU is disconnected, it advertises every 5 seconds.
When the BLE connection is disconnected, Press any RCU button to start direct advertising for 5 seconds to reconnect.
When reconnection is completed, all buttons of RCU output RF Code.

3.1.4 Factory Reset

Press about 5 seconds [Power] + [] Button, try the Factory Reset.
In case of Factory Reset, the BLE connection between the Sound Bar and RCU is disconnected. And the pairing information of the RCU is also deleted.
The RCU sends an un-pairing command to the Sound Bar before deleting the pairing information.
Sound Bar receives the Un-Pairing Command Code, it deletes the pairing information.

# Scheduled to be updated upon correction after H/W measurement.

3.7.2 Operating Voltage

RF Button Code output is possible up to 2.50V.

3.7.3 Cut-Off Scenario

Cut-off stops the use of the remote control to prevent damage to the circuit due to low voltage.
When the battery level is measured below 2.50V, the RCU operation stops.
When a voltage of 2.65V or higher is applied in the cut-off state, the RCU operates

3.8 BLE Protocol

3.8.1 Pairing Scenario

3.8.2 Key Packet Structure

4. CS-800 BLE Protocol consists of a total of 2 bytes..
5. Button Data is composed of 1 byte and means RCU Button Code.
6. Button State is composed of 1 byte and means the pressed state of the RCU Button.

1. The state when the button is first pressed is Press State (0x01).
2. The state of pressing the button is Repeat State (0x02).

A. If the button is kept pressed, the button state repeats every 100ms and the packet is repeatedly output.

3. When the button is released, the state is Release State (0x03).
