4. Basic function
4.1 Pairing and unpairing
Press and hold the Menu and Home, and keep for 3 seconds to enter the pairing mode for 30s.
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.
