Disable Pi Serial Console
Simple script to easily enable & disable the Raspberry Pi's serial console. Disabling the serial console is required if you want to use the Raspberry Pi's serial port (UART) to talk to other devices e.g. ATmega328 microcontroller on emonPi (see <http://elinux.org/RPi_Serial_Connection> for more information).
https://github.com/lurch/rpi-serial-console
$sudo wget https://raw.github.com/lurch/rpi-serial-console/master/rpi-serial-console -O /usr/bin/rpi-serial-console && sudo chmod +x /usr/bin/rpi-serial-console
$ sudo rpi-serial-console disable
$ sudo reboot
$ rpi-serial-console status
You should see the message Serial console on /dev/ttyAMA0 is disabled, the serial port is now free for communication with the ATMega328 on the emonPi
Setting Up Wifi
Using Edimax EW-7811
We need to edit the file /etc/network/interfaces on the root file system partition of the Pi's SD card.
Either connect Pi via Ethernet and access via SSH or connect a keyboard mouse and screen to the Pi or edit the file on your computer. Assuming your connect to the Pi via SSH:
$ sudo nano /etc/network/interfaces
Change interfaces file to the following entering your SSID and password.
auto lo
iface lo inet loopback
iface eth0 inet dhcp
auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-ssid "YOUR_SSID"
wpa-psk "WIFI_PASSWORD"
[CTRL] + [X] to save and exit nano
either reboot the Pi or just reboot the adapter
$ sudo ifdown wlan0; sudo ifup wlan0
Script to check for working wifi connection and restart wifi if needed https://github.com/dweeber/WiFi_Check
