How to Modify the Configuration File

Modify the Configuration File After Burning

• Configuration items that only take effect on the first startup must be modified by opening the configuration file config.txt in the removable disk FlyOS-Conf using a professional text editor after burning.

Online Configuration Modification After System Startup

• For ordinary configuration items, they will take effect after modifying them on the system's web configuration page and restarting the system.

  • Open the device's IP address in a browser, for example: 192.168.1.2/
  • For fluidd, uncheck as shown on the left in the picture.
  • For mainsail, check as shown on the right in the picture to display hidden files.
  • At this point, you can see the .flyos-config folder. Enter this folder to find the sys-config.conf file.
  • The sys-config.conf file is a soft link to the configuration file config.txt in the removable disk FlyOS-Conf.
  
  • Open the sys-config.conf file, modify the configuration items you need to change, then save -> close and restart.
  
  • Note: The format of configuration items in the sys-config.conf file is key=value, do not change it to key: value.
  • After modification and saving, restart the system to take effect.
