# Decoder for Continental / Nissan S180144020 key remote
|
|
# FCC ID: KR5S180144014
|
|
#
|
|
# Tested with 2x US 2013 Nissan Altima key fobs
|
|
#
|
|
# Operates on 433.92MHz with FSK at +/-32kHz. With the default low-pass
|
|
# filter of 10% of the sample rate, this means that a sample rate strictly
|
|
# greater than 320ksps must be used. For a RTL-SDR, that means passing
|
|
# "-s 1.024e6".
|
|
#
|
|
# The protocol was reverse engineered, so it may not be 100% complete. There
|
|
# are 3 possible packet types:
|
|
# - sync: 128 bits of all 0
|
|
# - code: contains the rolling code, always sent twice for redundancy
|
|
# - time: contains the amount of time that the button was held
|
|
#
|
|
# Every button press generates a sequence of sync, code, sync, code, time...
|
|
# packets. There is always a 100ms gap between packets. Time packets will
|
|
# be transmitted every 100ms until the button is released.
|
|
#
|
|
# More than one button can be held as well, which will set more than one bit
|
|
# in the 'button' field.
