Xibao

Introduction

Xibao vibrators are controlled over BLE using a 13-byte structured command packet with a simple additive checksum. The device must be placed in AI mode before BLE control commands are accepted.

BLE Profile

ble_names:
  - CCYB_1904
services:
  main:
    uuid: 0x0000fff0-0000-1000-8000-00805f9b34fb
    characteristics:
      tx: 0x0000fff2-0000-1000-8000-00805f9b34fb

Commands

Set Speed

13-byte write to Tx:

0x66 0x3a 0x00 0x06 0x00 0x06 0x01 0x02 0x00 0x02 0x04 XX YY

• XX — speed: 0x00 (off) to 0x63 (99, maximum)
• YY — checksum: (0xB5 + XX) & 0xFF

Checksum Calculation

YY = (0xB5 + XX) % 256

Notes

The device must be in AI mode (selected via the physical button) to accept BLE speed commands. Battery level, heater, and temperature control have not been documented.
