BLE name: ZALO-Queen
Servive UUID: 0000fff0-0000-1000-8000-00805f9b34fb
Tx Char UUID: 0000fff1-0000-1000-8000-00805f9b34fb

Tx prorocol: 0xAA 0xBB 0xCC
AA is mode:

• 01 is manual control
  BB controls the oscillator at the tip (values 01-08, 01 is off)
  CC controls the vibrator (values 01-08, 01 is low, no off)
• 02 is off
  BB and CC should be 01, but doesn't seem to matter
• 03 is pattern:
  BB is the pattern (01-08)
  CC is the intensity (01-08)

I suspect that the same protocol applies for all Zalo devices, but I only have the Queen.

BLE name: ZALO-King
Servive UUID: 0000fff0-0000-1000-8000-00805f9b34fb
Tx Char UUID: 0000fff1-0000-1000-8000-00805f9b34fb

Tx prorocol: 0xAA 0xBB 0xCC
AA is mode:

• 01 is manual control
  BB controls the vibrator (values 01-04, no off)
  CC controls the oscillator at the tip (values 01-08, no off)
  (it is reversed wrt the Queen)
• 02 is stop
  BB controls the vibrator
  CC controls the oscillator
  if BB or CC are 01, the respective function will be turned off
• 03 is pattern:
  BB is the pattern (01-08)
  CC is the intensity (01-08)
• 04 is shutdown
  BB and CC don't matter and can even not be sent

You can turn on just the oscillator by e.g. first sending 0x01 0x01 0x01 and then 0x02 0x01 0x00. I don't know if there's any other option.

I'm also attaching a log of all the things I was able to query via D-Bus.

@TheHardew I picked up a King... because I have issues... (See blackspherefollower/IoSTIndex#716)

I did some testing, and found that the vibrator on the King has a district tone difference between 4 and 8 (although the vibe's relativity weak so might not be noticeable to a real user).

I think this probably makes the protocol easier to document, since the 1 vibe and multi-feature devices have consistent control commands.
