# If "normal", bluetooth is always on.
# If "off", bluetooth is always off
# (Default: button)

# ----- INTERNET CONFIGURATIONS: -----

# Options for connectiontype:
#   "ethernet" connects to ethernet only
#   "wifi" connects to an existing router
#   "apinternet" turns the raspberry pi into a hotspot with internet connection
#   "aplocal" turns the raspberry pi into a hotspot without internet connection
#   "bridge" connects to an existing router, creates a raspberry pi hotspot and bridges these two connections.

# Change this value to true if you are using a hidden network
# (default: false)

# wifipassword: Insert the password of your wifi router. Leave field empty for open networks
# (Edit if "connectiontype" is "wifi" or "bridge")

# for Enterprise only, please leave it blank if you are not using WPA2-Enterprise

# hotspotname: Change to the name you want your hotspot to have, raspberry pi will be a hotspot with this name as SSID
# hotspotpassword:
#   Insert the password you want your Raspberry Pi hotspot to have. Can be blank for no password (open network)
#   Passwords must be 8 characters or more. If your password has less, it will be configured as open network
# (Edit if "connectiontype" is "apinternet", "aplocal" or "bridge")
