If you are re-imaging an existing PiAware site and want to keep your site statistics you will need to move the current site feeder-id to the new SD card image. You can find the current site feeder-id using one of the following methods:

• Go to the site's My ADS-B Stats page and find the "Unique Identifier"


• Or enter the following command on the command line on the current Pi:
  cat /var/cache/piaware/feeder_id
  


• Or connect a monitor to the Pi system

Follow the instructions found in Step 2 of the PiAware build page to download the latest PiAware image and write it to the SD card.

Follow the instructions found in Step 3 of the PiAware build page to edit the /boot/piaware-config.txt file on SD card.

Add the feeder-id recorded in Step 1 to the end of the config file with a new line that looks like:

Remember to replace the bold value shown above with the feeder-id saved in Step 1.

If you are using Wi-Fi, you can also edit the wireless-ssid and wireless-password values at this time.

After making the changes, save the file and safely eject the SD card.

Insert the SD card in the Raspberry Pi and power it on.

After a few minutes, go to the My ADS-B Stats page and verify that the site has green status indicators

• Check your power and cabling
  • Check the power cable and verify there is LED activity on the Raspberry Pi. The power LED should be a steady red and randomly flashing green.
  • Verify that you are using a 5.1V 2.4A power supply.
  • If you are using an Ethernet connection, verify that the cable is plugged into the Raspberry Pi and the ethernet LEDs are lit.
  • If your Pi has power but you are not seeing aircraft, verify that the cable connections to the antenna are secure and tight.


• Or connect a monitor to the Pi system
  
  • Verify that at least one of the network interfaces has an IP address and the feeder-id matches the original value from Step 1.
  • If neither of the network interfaces are working or the feeder-id is wrong, connect a keyboard, press Alt+F2, and log into the console using username pi and password flightaware
  
  Once you are logged in, enter the command piaware-config to display the current settings.
  
  Use piaware-config to update any incorrect values. For example:
  • piaware-config wireless-network yes
  
  
  
  
• If you cannot connect a monitor to the Raspberry Pi, power off the Raspberry Pi, move the microSD card to a different computer, and verify the contents of /boot/piaware-config.txt
  Verify the following settings are correct:
  • wireless-network
  • wireless-ssid
  • wireless-password
  • feeder-id

  After making any corrections, safely eject the microSD card, insert it in the Raspberry Pi and power up the Raspberry Pi.

• Try accessing PiAware locally
  • If your PiAware site has a local IP address, try accessing SkyAware with a browser.
  • Try the Site Local IP listed on My ADS-B Stats page
  • If that IP address does not work, follow the steps in the PiAware FAQ to determine the local IP address.
  • If you can view SkyAware but PiAware cannot access FlightAware.com:
  • Verify that your internet connection is working.
  • Check for a firewall on your network and open ports, if required. See the PiAware FAQ
