Specifications

1. PAIRING
1.1. Pairing Trial
- Press and hold [Voice] key and [OK] key together for 3 seconds while the remote control unit is unpaired
- Pairing trial is started by transmission of IR Trigger code
- Top LED blinks every 330ms for Un-Direct Advertising for up to 30 seconds.
1.2. Pairing Success
- If RCU and STB succeed in pairing, RCU blinks Top LED 3 times and the pairing process completes.
- Pairing success is determined after all Client Characteristic Configuration is received.
1.3. Pairing Failure
- If the pairing fails, RCU stops the LED Blinking and returns to the previous state.
2. UNPAIRING
- Press and hold [OK] key and [BACK] key together for 3 seconds for unpairing
- RCU deletes the pairing information and blinks Top LED 3 times at intervals of about 250ms and terminates unpairing
- When unpairing is performed, unpairing code is transmitted to synchronize with STB
- RCU can be unpaired at any time regardless of the connection status with the STB
3. Key Operational Specifications
3.1. Basic Keys operational specs
- When key is pressed, RCU operates as IR or BT according to the connection status and LED turns on
There is no LED action for key input during pairing attemption
- When two keys or more keys are pressed at the same time, IR transmission is stopped.
- Release code is transmitted when 2 keys or more keys are pressed at the same time in case of RF mode
- If one key is released while 2 keys are pressed, the data of the remaining key pressed is transmitted
3.2. Keys operational specs in BT mode
- When connected, all keys except TV key operate with RF
- In the Disconnected state, Direct Advertising is performed for 10 seconds to re-connect when any key is pressed.
- IR should work in any case that BLE doesn't work.
4. Voice Search Operation Specifications
- When [Goole Assistant] button is pressed, RCU transmits the code for activating the voice search function to STB
- When RCU receives the Mic Open Command from STB, the Top LED turns on and starts voice packet transmission
- User performs a voice search when the Top LED on RCU is turned on
- When RCU receives a Mic. Close Command from STB, the voice packet transmission ends and LED turns off
- Even if STB doesn't send a Mic. Close Command, RCU automatically ends the voice packet transmission after 20 sec. timeout
5. Battery Level Information
- STB can read battery voltage levels from RCU when battery information is needed
- Battery voltage level information : Battery level(2.0V~3.0V)의 Percentage[%] (0x00~0x64)
ex) Voltage level display example
V %
3.10 100%
3.00 100%
2.85 85%
2.64 64%
