Features

Connection Management

WebSocket Server: Built-in WebSocket server (default port 12346) for T-Code input
Protocol Detection: Auto-detects T-Code vs Buttplug protocol
Real-time Status: Live connection status and error reporting

Bluetooth Integration

Device Discovery: Scan for DG-LAB Coyote devices (identifier: "47L121000")
Adapter Selection: Support for multiple Bluetooth adapters
Battery Monitoring: Real-time battery level display
Automatic Reconnection: Robust connection handling with auto-connect option

Dual Channel Control

Independent Channels: Separate control for channels A and B
Frequency Control: 1-200 Hz with precision period calculation
Frequency Balance: 0-255 range for waveform feel adjustment
Intensity Balance: 0-255 range for pulse width control
Real-time Updates: Live parameter synchronization with device

Parameter Linking (T-Code to Channel Mapping)

Any channel parameter can be dynamically linked to any T-Code axis:

6 T-Code Axes: L0-L2 (Stroke, Twist, Roll) and R0-R2 (independent axes)
4 Parameters per Channel: Frequency, Frequency Balance, Intensity Balance, Intensity
Curve Transformations: Linear, Exponential, Logarithmic, S-Curve, Inverse
Range Mapping: Configure min/max output values for each axis
Midpoint Mode: Use distance from center position instead of absolute value
Curve Strength: Adjustable 0.1-3.0 strength for exp/log curves

Presets System

Save/Load Presets: Store complete channel configurations
Ecosystem-Scoped: Separate presets for T-Code and Buttplug input modes
Dirty Tracking: Visual indicator when preset has unsaved changes
Quick Selection: Inline preset selector in header

Buttplug Integration (Work in Progress)

Experimental support for Buttplug.io protocol:

Feature Types: Position, Vibrate, Rotate, Oscillate, Constrict
Feature Pipeline: Position → Motion → Vibrate → Constrict
Configurable Counts: Set number of each feature type

Advanced Features

Processing Engines: Multiple algorithms (v1, v2-Smooth, v2-Balanced, v2-Detailed, v3-predictive)
Keyboard Shortcuts: Fully configurable hotkeys
Output Pause: Spacebar to pause all stimulation

Modern UI

Dark Theme
Responsive Design: Adaptive layout for different screen sizes
Real-time Feedback: Live parameter display, waveform visualization
Range Sliders with Indicators: Visual feedback showing linked parameter values

Installation

Download the latest release from the GitHub Releases page.

Usage

Initial Setup

Open WebSocket Server
- The WebSocket server starts automatically (configurable)
- Default port: 12346
- Connect your T-Code source (e.g., Funscript player, custom scripts)
Scan for Bluetooth Devices
- Click "Scan for Devices" to discover DG-LAB Coyote devices
- Select your device from the dropdown
- Click "Connect Coyote" to establish Bluetooth connection

Channel Configuration

Parameter Linking

Each parameter (Frequency, Frequency Balance, Intensity Balance, Intensity) can be:

Static: Manual slider control
Linked: Dynamically controlled by a T-Code axis with curve transformation

Example: Link Channel A Intensity to L0 (stroke axis), and Channel B Intensity to L0 with Inverse alignment

Range Limits

Percentage Range: Adjustable min/max intensity scaling
Visual Feedback: Real-time percentage display with input position indicator
Independent Channels: Separate limits for each channel

Presets

Configure channels as desired
Click the + button to save as new preset
Select presets from the dropdown to load
Click the save icon to update an existing preset

T-Code Protocol

Supported axes: L0, L1, L2, R0, R1, R2

L0<position> - Set axis position (0-9999)
L0<position>I<interval> - Ramped movement over time (ms)

Examples

L0500      # Set L0 (stroke) to 50%
R2750I1000 # Ramp R2 to 75% over 1 second
L09999     # Set L0 to maximum
L00        # Set L0 to minimum
DSTOP      # Emergency stop all channels
