 CSR8645 software version introduction:
1. Keys: There are 6 function keys: POWER-EN, PLAY, VOL +, VOL-, PREV, NEXT.
    The key functions are described below:
     POWER-EN: When the switch control module is turned on and off, by turning the switch, when POWER-EN is connected to BAT, the module is turned on; when POWER-EN is disconnected from BAT, the module is turned off, usually when the battery is powered. When the module is powered on and powered on, simply connect the POWER-EN series 10K resistor to BAT to achieve power on and power on the module, which is usually used for external power supply.
    PLAY: play / pause (short press), answer / hang up (long press, slightly longer), re-pair (long press)
    VOL +: Volume up
     VOL-: volume reduction
     PREV: Previous song
     NEXT: next song
2. LED: pairing status, dual lights flash alternately, after pairing, single light flashes;
3. USB sound card function;
4. 3.2V low power alarm, 3.0V automatic shutdown, (AMS1117 power supply is realized);
5. The maximum charging current is set to 250MA. When the lamp is full, it will go out and turn on another lamp (personally recommend using a charging module, fast);
6. Always pairing when not connected;
7. Can connect 2 mobile phones at the same time;
8. MUTE: The EN control pin of the audio amplifier. When it is muted, it outputs a low level after a period of time; when it is playing, it outputs a high level (1.8V).
