# A proof of concept to watch for
# and respond to Meshtastic
# messages over serial (USBserial).
#
# More here than the first paste.
#
# Can be thought of as a bash-based
# BBS or Meshtastic Bot.
#
# Requires: bash, stty, meshtastic (cli),
# sed, tr, grep...
#
# Make sure "Debug log enabled"
# is checked to on in the
# Radio Configuration->Device menu
# of Meshtastic
