Byte	Description	Range
0x55 0xAA	Header	Fixed
0xF0	Command type	Fixed
0x01	Unknown	Fixed
YY	Incremental counter	0x01+ (not required to change)
0x0B 0x65 0xF7 0x01 0x01	Unknown fixed bytes	Fixed

Notes

• The counter byte (YY) is described in the issue as an incremental counter starting at 0x01, but the Buttplug implementation always sends 0x01 — changing the counter is not required.
• Speed range is 0-100 decimal (0x00-0x64).
