# simple script to get a vehicle fingerprint.
# Instructions:
# - connect to a Panda
# - run selfdrive/boardd/boardd
# - launching this script
# Note: it's very important that the car is in stock mode, in order to collect a complete fingerprint
# - since some messages are published at low frequency, keep this script running for at least 30s,
# until all messages are received at least once
