# https://github.com/taoteh1221/Bluetooth_Internet_Radio
# Fully automated setup of bluetooth, internet radio player (PyRadio), local music files player (mplayer), on a headless RaspberryPi,
# connecting to a stereo system's bluetooth receiver (bash script, chmod +x it to run).
# To install automatically on Ubuntu / RaspberryPi OS / Armbian, copy => paste => run the command below in a
# terminal program (using the 'Terminal' app in the system menu, or over remote SSH), while logged in AS THE
# USER THAT WILL RUN THE APP (user must have sudo privileges):
# wget --no-cache -O bt-radio-setup.bash https://tinyurl.com/bt-radio-setup;chmod +x bt-radio-setup.bash;./bt-radio-setup.bash
# AFTER installation, ~/radio is installed as a shortcut command pointing to this script,
# and paired bluetooth reconnects (if disconnected) when you start a new terminal session.
# A command line parameter can be passed to auto-select menu choices. Multi sub-option selecting is available too,
# by seperating each sub-option with a space, AND ecapsulating everything in quotes like "option1 sub-option2 sub-sub-option3".
# Running normally (displays options to choose from):
# ~/radio
# Auto-selecting single / multi option examples (MULTI OPTIONS #MUST# BE IN QUOTES!):
# ~/radio "1 y"
# ~/radio "upgrade y"
# (checks for / confirms script upgrade)
# ~/radio "7 1 b3"
# ~/radio "internet 1 b3"
# (plays default INTERNET playlist in background, 3rd station)
# ~/radio "9 1 bs"
# ~/radio "local 1 bs"
# (plays default LOCAL music folder [RECURSIVELY] in background, shuffling)
# ~/radio 10
# ~/radio off
# (stops audio playback)
# ~/radio "12 XX:XX:XX:XX:XX:XX"
# ~/radio "connect XX:XX:XX:XX:XX:XX"
# (connect bluetooth device by mac address)
# ~/radio "13 XX:XX:XX:XX:XX:XX"
# ~/radio "remove XX:XX:XX:XX:XX:XX"
