SENT (Single Edge Nibble Transmission)

The SENT (Single Edge Nibble Transmission) protocol is used in automotive electronics for data transmission between sensors and ECUs (for example wheel-speed or position sensors). It supports efficient, high-precision transfer within limited bandwidth.

Incorrect Clock Tick, Tolerance, # of Nibbles, SENT Version, or Message format relative to the device causes decode failures. For channel-prefix differences, see Settings.
