4. Basic function

4.1 Pairing and unpairing

  • Press and hold the Left mouse button and somatosensory button for 3 seconds, the red LED will start to flash and enter the pairing mode for 60s.

  • The pairing is successful and the red light will be on for 1s.

4.2 Re-Connect

The remote control does not actively initiate disconnection and maintains a long connection. When there is pairing information and the Bluetooth connection is disconnected, press any key to send a re-connect broadcast.

4.3 Sleep and wake up

When there is no data interaction, the remote control remains connected and enters the dormant state, and the remote control does not actively enter the disconnected state. Press any key to wake up the remote control. If it is still connected, the Bluetooth code value of the corresponding button will be sent; if it has entered the Bluetooth connection disconnected state, it will enter the reconnect state.

5. Advanced function

5.1 Voice control

In the remote control, the main chip capture the voice data through a high-SNR microphone and noise reduction based on built in codec and then transmits it to the host via Bluetooth. The host decompresses the data and performs ASR (voice recognition).

 

Through this function, users can control TV/STB and other devices with sound.

Remark 1: The advantage of this product is high SNR MIC + internal Codec noise reduction to ensure the quality of voice data, and the correct rate of voice recognition reaches 98% (5 meters)


Remark 2: High-performance speech library SDK can be provided to facilitate some customized needs of customers.

5.2 Air mouse

Built-in high-precision 6-axis gyroscope, after the main chip collects raw sensor data, based on Invensense (TDK) robust Motion engine and firmware algorithms.

​

The air mouse function is turned on and off using humanized automatic judgment logic. When the remote control is detected to be shaken strongly, the air mouse function is automatically turned on, and the air mouse function is automatically turned off when the remote control is detected not to be shaken within 5 seconds.

Remark 1: 

The advantage of this product is 

1. Eliminate Hand shake

2. Directional compensation

3. Key effects are eliminated

6. Unique function

6.1 Touch pad

The product has a touch control function, users can swipe left or right to switch pages.

​

Remark 1: Capacitive touch chip with functional sensitivity supports operation with medical gloves
