M5StickC Plus: What is the range of the volume

[Dario]

In UIFlow there is Speaker.volume block for the M5StickC Plus. What is the range of the volume?
I guess that 0 is the minimun (no sound). But what is the value for the maximum volume?

[Dario]

I'm refering to this block:

What is the volume range?
0 to 100?
Something else?

In UIFlow there is no documentation at all about this block and in M5StackDocs there is no range.
@Zontex Can you please get this information?

Hi Dario, sorry missed your post.
Yes, the range is 0 to 100 and we will add the documentation on the block into the UIFlow, thank you for noting that!

It seems the value is PWM duty cycle. So the volume increases in the 0-50% and then decreases in the 50-100%.
