A professional trailer diagnostic tool that connects via Bluetooth Low Energy to monitor PWM signals, IO status, and voltage data in real time.
Comprehensive diagnostics for trailer testing
Automatically scan and connect to BLE devices starting with TTester. One-tap pairing with low-power real-time communication.
Live display of PWM frequency, duty cycle, and Aux voltage values. Data parsed in little-endian format for precision and reliability.
Intuitive status lights for test mode, left/right test signals, and reverse status. Automatic audio alerts on state changes.
Set PWM frequency parameters remotely via BLE write characteristics with millisecond-level precision.
Easily manage connected devices, switch between devices, and view connection history.
All data is transmitted locally between your device and the BLE peripheral. No personal data is collected.
