Use Cases
From workshop WiFi diagnostics to mobile app integrations — the Telematics ECU handles the wireless layer so your team can focus on the application.
Push firmware updates over WiFi to any CAN-connected ECU in the vehicle. No physical programming access needed — ideal for fleet deployments.
Run UDS diagnostics over WiFi from a laptop or tablet on the workshop floor. Replaces wired CAN dongles for routine service checks.
Pair with Android or iOS apps via BLE — expose vehicle data, control outputs, or unlock features from a smartphone without any additional hardware.
Capture CAN traffic and stream it over WiFi to a local server or cloud endpoint. Useful for vehicle testing, calibration, and data analytics.
Trigger CAN messages and DO outputs from a WiFi/BLE command — remote lock/unlock, accessory control, or feature flag switching.
Use as a wireless stimulus generator on the test bench — inject CAN messages or read sensor states without running cables across the test rig.
