LiBo Vibration Protocol

Introduction​

Most LiBo (and Sistalk-branded) devices use a shared BLE service for vibration control. Speed and pattern are sent as a single byte. Some devices have a secondary characteristic for suction. The ELLE/Whale and Shark devices use different command structures; see their respective protocol pages.

Covered devices: Lottie, LuLu, LaLa, Carlos, Lina, Adel, Lily, Lucy, Karen, Sistalk MonsterPub.

Commands​

Vibration / Pattern (0x6001)​

Send a single byte:

  • 0x00–0x64 = speed (continuous vibration)
  • 0x65–0x6c = pattern index

Suction / Secondary Channel (0x6002)​

For LaLa and Carlos suction control:

  • 0x00–0x03 = suction intensity patterns

Some devices (notably Sistalk MonsterPub) do not stop completely on 0x00 to 0x6001 alone — also send 0x00 to 0x6002 to fully stop.

Pressure / Battery (0x6051)​

Read or subscribe. Returns 1 byte: 0x64 = 100%.

Karen exception: Uses 0x6050/0x6051 for pressure (4 bytes, meaning unknown) and 0x6070/0x6071 for battery.

Notes​

  • Karen (SuoYinQiu) has no vibration motor; only pressure sensing.
  • MonsterPub Gen 2 devices require an authentication handshake before accepting commands. See docs.buttplug.io#19 for the auth protocol details.
  • The MonsterPub Gen 2 auth involves reading from characteristic 0x8001, selecting a 4-byte key based on the first byte, XOR-ing the challenge bytes against the key, and sending a 15-byte response.
