CK6855M1 Bluetooth Offline Voice Recognition Light Control Module User Manual

——————————————-——————————————-——————————————-——-

1. Function Description

CK6855M1 module is an offline Bluetooth voice recognition module designed specifically for lighting products. The module supports infrared remote control reception, RGB+W+Y light control, stepless dimming, AD button light control, and audio playback control, supporting Bluetooth 5.1 music playback. Users only need to follow the wiring diagram to successfully implement the product’s functions and achieve production goals.

2. Why Design CK6855M1

1. 1. This is a brand new solution aimed at solving the problem that traditional lighting products require a remote control or buttons to control different lighting modes, whileCK6855M1 liberates hands to achieve voice control.
2. 2. Traditional lighting can only serve as a lighting product, whileCK6855M1 module not only has5 channels of PWM for lighting control but also features Bluetooth 5.0 audio playback, bringing an innovative chip product to the traditional lighting industry.
3. 3. Unlike networkWIFI AI voice recognition, AI recognition requires cooperation with an APP or obtaining copyrights from certain platforms, and products controlled by AI are limited byWIFI connectivity, which is significantly affected by the instability of theWIFI connection. If the network speed is unstable, it can directly lead to ineffective or failed voice control. However,CK6855M1 does not require aWIFI connection, eliminating control issues.
4. 4. CK6855M1 features all light control programs are pre-set and ready to use, with remote control reception already configured, including the mute function for amplifiers, which can basically meet the needs of all Bluetooth bulb/ceiling lights/table lamps on the market without excessive modifications for immediate use.
5. 5. CK6855M1 has a standby power consumption of 15mA, which is not suitable for battery-powered products. We will address this pain point in future versions, so stay tuned.

9. Frequently Asked Questions

Question	Can I connect Bluetooth and play music just by powering it on?
Answer	After powering on, the light circuit can connect to Bluetooth from the mobile phone and play music
Question	Why is the infrared remote control not working?
Answer	Check if the infrared receiver pin is connected correctly, then check if the infrared remote control’s code and values match
Question	Why is there no sound from the connected amplifier?
Answer	For amplifiers that turn off at high level, add a pull-up resistor to the MUTE pin; for amplifiers that turn off at low level, add a pull-down resistor to the MUTE pin
Question	Can it pass certification? Is there technical support for certification?
Answer	The chip has passed BQB, and all certifications can be supported with technical services provided
Question	How do I adjust the light mode?
Answer	You can adjust it using the remote control / AD port touch button / voice command
Question	Can I add my own commands? Can foreign language commands be added?
Answer	Yes, you can customize commands with the factory, specific business conditions can be consulted with the manufacturer
Question	Is there a power limit for the LED lights?
Answer	No. Just connect the corresponding color LED beads according to the module’s light control interface
