Full details on the command sequence?

[offbeatmammal]

so, I've been playing around with a Blynklight and NodeJS and, by treating it as a HID, I can send colors to it and control flashing:
    
commandBuffer[0] = 0x00;
commandBuffer[1] = red;
commandBuffer[2] = blue;
commandBuffer[3] = green;
commandBuffer[4] = blink ? 100:0; // 0 is stable, 70 is fast blink, 100 is medium blink
commandBuffer[5] = 0x00;
commandBuffer[6] = 0x40;
commandBuffer[7] = 0x02;
commandBuffer[8] = 0xFF; // End of control sequence: controlCode & 0xFF

but... I can't work out how to control either the brightness or play the ringtones (and control volume)

Does anyone have a more detailed breakdown of the control sequence?

Hi,

I know how to do this.

commandBuffer[0] = 0x00;
commandBuffer[1] = red;
commandBuffer[2] = blue;
commandBuffer[3] = green;
commandBuffer[4] = lightControl
commandBuffer[5] = musicControl1
commandBuffer[6] = musicControl2
commandBuffer[7] = 0xFF;
commandBuffer[8] = 0xFF;

ligthtControl byte => Bit7-Bit0

Bit0: 0 - Light On, 1 - Light Off

Bit1: 0 - No Dim (Full Brightness), 1 - Dim by 50%

Bit2: 0 - No Flash, 1- Start Flash (Blink)

Bit5-Bit3 - Flash speed - 001 - slow, 010 - medium, 100- fast


musicControl1 byte => Bit7-Bit0

Bit3-Bit0: Choose music, corresponding from the music 1 to music 10 respectively,total 10 music

Bit4: 0 - Stop Playing Music, 1 - Start Music Play

Bit5: 0 - Stop Music Repeat, 1 - Start Music Repeat

Bit6-Bit7: 00


musicControl2 byte => Bit7-Bit0

Bit3-Bit0: 1-10 corresponding from 10% volume to 100% volume respectively, total 10 level volumes

Bit6-Bit4: 000

Bit7: 0 - Clear Mute, 1 - Mute Volume

Hope its clear now.
