4. Basic function

4.1 Pairing and unpairing

  • Press the OK button, and keep for 3 seconds, the white backlight 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 Universal IR

By cooperating with the far unit device, the infrared device (TV, set-top box, fan, etc.) that needs to be controlled on the far unit device page, after selecting the device brand, the far unit will transmit its corresponding code value to the remote control via Bluetooth ,After the remote control receives the code value, it sends out an IR control signal through its own IR hardware circuit to achieve the function of controlling the infrared device.


If there is an IR database for various devices in the cloud, then various devices can be controlled through the remote control.

Remark 1: The advantage of this product is that the response time is within 1s.

6. Unique function

6.1 Find Me

This product has the Find me function. The user can select the Find me option through the page on the TV, and the remote control will beep to remind the user of its location, so that it is easy to find the missing remote control.

Remark: This function is only available when the remote control and the far unit have established a Bluetooth connection.

6.2 Pickup wakeup

The product has a pickup wakeup function. The product has a built-in high-sensitivity gyroscope that can detect that the remote control is being picked up, and then wakes up the remote control to quickly establish a Bluetooth connection, confirming that the next key operation can be quickly responded, and the remote control will also At the same time, the backlight lights up, so that users can better see each button in dark conditions.
