# setconn

# Sets up connman on the BeagleBone Blue via SSH over USB.
# Assumes one of the standard Debian images.

# You need only specify your WiFi SSID and password (NOT that pesky hashed ID).
# Afterwards, SSH over WiFi to the BeagleBone (via your router) will be ready to go.
# (You can discover the BBone's local IP address using your router or nmap, etc.)

# Name this script 'setconn', and make it executable with 'chmod 0744 setconn'.
# NOTE: When you are prompted with '[sudo] password for debian:', don't type anything;
# just wait a couple of seconds, and the script will continue fine by itself.

# Now, before running it, edit the following lines as appropriate:

remote_uses_SSID="BTHub4-HDOV"  # Change to your WiFi SSID.
remote_uses_pwd="abcdefghijkl"  # Change to your WiFi password.
remote_default_user="debian"  # This is the default. Probably leave it alone.
remote_default_user_pwd="temppwd"  # This is the default. Probably leave it alone.
remote_ip="192.168.7.2"  # This is the default. Probably leave it alone.
