This project is using version 1.8.1.

You will need to a hrefhttps://www.patreon.com/KM6LYW/posts>give Craiger a dollar/a> to get access to the image. Burn it to an SD Card and boot the Pi. Use your browser to connect and configure DigiPi. This is all documented on the DigiPi page./p>p>The DigiPi will boot into Access Point mode. Connect to this network and browse to 10.0.0.5. You should start with “initialize” to add your Call Sign, Latatude, Longatude and Grid Square. You can then choise “Shell” menu option or SSH to login-in. The USER is pi and the PASSWORD is raspberry. Next run strong>sudo remount/strong> and/or you may need to run strong>sudo systemctl daemon-reload/strong>./p>p>Use the menu option Wifi to configure Wifi and other Raspberry Pi settings./p>p>Edit strong>/etc/systemd/system/digipi-boot.service/strong> to change the default mode to DigiPeater.
