Protocol
The control protocol for the Vibratissimo allows the user to:
- Read the battery level
- Read device infos (product id, expected UI for app)
- Control motor(s)
- Control electro shock
Info Characteristic Format
To trigger a notification or select the value to read, it is necessary to write VOLT (0x564F4C54) or WNDS (0x574E4453) to the characteristic first.
The format for read values is
0xAA 0xBB 0xCC 0xDD
If BB and CC are zero, then AA is the battery level as a percentage (0-100).
If CC is 0x40, then AABB is the product value and DD is the UI value.
| Product | product value | UI value |
|---|---|---|
| Jefferson | 0000 | 0B |
