openpilot: OG Eon tri-state switch mod + auto-enable WiFi hotspot

continue.sh

#!/usr/bin/bash

# Adapted from Erich's tri-state switch mod which allows choosing from three installed openpilot locations on boot
# I've only really added some error-checking and fallback options
# Boot locations:
#  /data/openpilot.1
#  /data/openpilot.2
#  /data/openpilot.3
#
# Moves existing real /data/openpilot dir (I.E not a symlink) to /data/openpilot.backup
# Tries to boot the remaining locations if the first choice doesn't exist
# Preserves LiveParameters and kegman.json for each boot location

# Turn on WiFi hotspot on boot
# Want to add (probably need to make separate script, actually):
#  -Wait 60 sec on boot and cancel if WiFi is already connected to something
#  -Turn off hotspot if not 'driving' for 5 minutes (maybe watch if controlsd is running)
#
# service call wifi 37 i32 0 i32 [X]  # X: 1=on, 2=off
service call wifi 37 i32 0 i32 1
