===== [RPi] NetworkManager and m2siame AP ... =====
We'll now explain how to setup 'NetworkManager' on your Raspberry Pi ... to add a WiFi connexion to the SSID:m2siame

<file bash nm_setup.sh>
apt-get -y install network-manager
apt-get -y install network-manager-gnome
apt-get -y remove modemmanager

cat > /etc/network/interfaces << EOF
# NetworkManager: minimum interfaces
# François July,16
#
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

auto lo
iface lo inet loopback
EOF

systemctl stop dhcpcd
systemctl disable dhcpcd
systemctl disable wpa_supplicant
pkill -9 wpa_supplicant

sed -ie '/^managed=/s/=.*/=true/g' /etc/NetworkManager/NetworkManager.conf
sed -i '/^\[main\]/a monitor-connection-files=true' /etc/NetworkManager/NetworkManager.conf

systemctl enable NetworkManager
reboot
</file>
\\

In case you need CLI to NetworkManager to add a WiFi connexion:
<code>
nmcli con add con-name m2siame ifname "*" type wifi ssid m2siame
nmcli con modify m2siame wifi-sec.key-mgmt wpa-psk
nmcli con modify m2siame wifi-sec.psk <passphrase>

nmcli device wifi rescan
nmcli --wait 30 con up m2siame
</code>
\\
To gain access to our network, you first ask for:\\
  * <wrap hi>RPi's WiFi MAC addr registration</wrap> in the DHCP server,
  * WiFi [[protected:wifi|passphrase]] (teacher only).
