SENT Decoder

SENT Decoder is a professional configuration and monitoring tool for the

SAE J2716 SENT (Single Edge Nibble Transmission) automotive sensor protocol.

FEATURES

• Live monitor — real-time decoded values from 2 independent SENT bus inputs

• Oscilloscope view — waveform traces for both channels and all 4 analog outputs

• Full decode configuration — nibble counts (0–4 per channel), bit window, byte

order (MSB/LSB), tick period, CRC validation, pause pulse, serial message mode

• AO routing — route any decoded channel to any of the 4 analog outputs (DB15)

• Scaling — set min/max range per output with fail-safe value

• Sensor presets — built-in library for Bosch, Continental, Honeywell, Denso,

NXP and more. Save custom presets. Fetch community presets from cloud.

• BLE connection — connects to SENT Decoder hardware via Bluetooth 5.4

(Raytac MDBT50Q-P1MV2 / nRF52840)

• .sentcfg files — export and import complete configurations in JSON format,

compatible with the PC configuration tool
